Read about the latest news on ECG / EKG Machines

Just when you thought there couldn’t be many more technological advances in medical equipment, Japan’s National Institute of Information and Communications Technology (NICT) has developed an electrocardiograph that displays measurable data on a mobile phone. That’s right, an EKG machine that can be worn like an accessory.

This electrocardiograph machine uses a wireless, short-distance communication system and can perform EKG machine testing around the clock while transmitting data wireless, but the best part is, it can be worn like a necklace. The NICT expects this new electrocardiograph to become a staple of personal health management as it will help patients monitor their heart rhythms during everyday life.

Not only can this new device perform an electrocardiogram, it can also measure temperature changes on the surface of the body and overall body posture. Lightweight and portable, it also requires no conductive gel, so it can be worn around the neck all day without making the patient feel uncomfortable. Additionally, this portable EKG machine has a low-power security function, which encrypts the data dynamically for each user and helps reduce power consumption by using only the amount of power needed to remain operable.

Researchers at NICT expect this new device to be sold to medical practitioners who work with chronically ill heart patients and people who require extensive testing to diagnose a heart abnormality. As the demand increases for this portable EKG monitor, global medical equipment manufacturers are expected to offer devices like this at more competitive prices. Look for more information to be released by NICT as the product completes its final round of clinical trials.

Did you know that more than 70 million adults in the US have high blood pressure? So prevalent is this health problem in the US that it has many doctors scrambling to find an effective solution.

Blood pressure is a measurement of the force with which blood is pushing its way through blood vessels and arteries. Any time that blood pressure is up; it means that the heart has to work much harder, which could lead to a number of serious illnesses, including heart attack, congestive heart failure, stroke or aneurysm.

Doctors will normally check blood pressure at a routine check-up and order an EKG machine test for older patients or those at high risk for hypertension. The reason why high blood pressure is so concerning is because it is usually an indicator of present or future heart disease, which is the number one killer in America. It can also cause cardiovascular damage and complicate other health problems.

According to most physicians the “normal” blood pressure level is 120/80 or lower. Even a measurement that is slightly higher than this can indicate a condition called pre-hypertension, but high blood pressure is usually diagnosed when blood pressure exceeds 140/90.

Some symptoms of hypertension include headaches, dizziness, fatigue, vision problems, chest pains, irregular heartbeat and nausea. While there are a number of highly effective prescription drugs on the market to help control high blood pressure, lifestyle changes are sometimes the best medicine.

So how is high blood pressure controlled? Proper exercise, a healthy diet, weight loss, and reduced salt and alcohol intake can help a lot, but it is also important to get regular screenings. Most doctors will recommend an electrocardiogram, using a 12-lead EKG machine, as well as a stress test and dietary changes. Controlling high blood pressure can be a quite challenge but “take heart”, it can be done!

EKG machines are used to measure the electrical signals of the heart, but these electrical measurements can often be misleading. This is especially true when EKG machines are used to diagnose left ventricular hypertrophy (LVH). In most cases, doctors need to order more tests before coming to a final diagnosis of this disorder.

According to a recent study by the Henry Ford Medical Center, up to 82 percent of patients who were screened with an EKG machine test received a false positive reading and about 7 percent were given a false negative result. This study was conducted with a control group of 500 patients.

When study researchers analyzed the EKG data against other test results, they found that CT scans were a better predictor of the disease. This is because a CT scan takes a series of images of the heart, while EKG /ECG machines only measure the electrical activity. Once a diagnosis of left ventricular hypertrophy (LVH) is evident, patients are usually given additional testing, such as an echo-cardiogram and an MRI scan.

LVH causes a thickening of the heart’s lower left chamber, and is usually caused by another medical condition, like hypertension, but unfortunately the disorder is often misdiagnosed or undetectable until it has significantly progressed.

Further research must be done to determine the best method of testing for LVH, because it can be serious. People with LVH are often more susceptible to other cardiovascular diseases, including heart failure, myocardial infractions, stroke and abnormal heart rhythms.

Have you ever wondered why a stroke can be a relatively minor event in some people, and a death sentence for others? A recent study shows by the University of Rochester School of Medicine shows that patients with abnormal electrical impulses in the heart are at a much more likely to die within 90 days when they suffer an ischemic stroke.

According to recent research, when a patient’s QTc intervals are greater than 438 milliseconds (in men) and 440 milliseconds (in women) their prognosis after suffering a stroke is not good. QTc intervals are a measurement of the heart’s electrical activity, and are detected with EKG machines.

One important finding in this study was that Emergency Room staff members often forget to review a patient’s current prescription medications to determine they could play a role in lengthening their QTc intervals. When a QTc interval is too long, electrical signals take longer to pass through the heart’s ventricles. A simple EKG machine can diagnose this type of disorder in patients.

Not all electrical abnormalities of the heart are caused by prescription drugs, however. In many cases, it is caused by a genetic disorder or congenital heart disease. EKG machines, which measure the electrical waves in the heart, as well as other cardiology tests, are used to determine the cause of the disorder.

Further research must be done to measure the relationship between QTc intervals and high death rates from an acute ischemic stroke. A recent Mayo Clinic study revealed that only 70% of patients with longer QTc intervals survived for three months after an ischemic stroke, while 87 percent of those without the disorder survived. Also, among those with prolonged electrical intervals who did survive past 90 days, their functionality was poorer than those with normal heart activity.

Overall, doctors should pay close attention to the electrical activity of their patients’ hearts, especially in patients with chronic heart disease. This can be done through regular testing on an EKG machine.

EKG machines are still one of the most important diagnostic tools used in health care environments and doctors rely on them to save lives or diagnose the presence of heart disease. By detecting and recording the electrical impulses of the heart, an EKG machine informs physicians of cardiac abnormalities. ECG machine tests can also be used as part of an overall physical exam, particularly for older patients.

While most EKG machines are used when a patient is lying on an examination table, doctors often order stress tests to test the heart’s reaction to physical activity. Either way, a set of electrodes are attached to the patient’s arms, legs and chest. Each electrode, or lead, is connected to an EKG machine, which then measures the electrical activity of the heart from various angles.

Once a technician starts the machine, it starts to record electrical activity in the form of wave tracings. These measurements appear on the machine’s screen in real time, and are also printed out on paper for later analysis. If any immediate abnormalities are evident, they are marked up for future examination by a doctor.

The three waves used in accurate EKG machine readings are the P, QRS and T waves. P waves are low-amplitude waves that measure the impulses from the atria. QRS waves are high-amplitude and measure ventricular impulses, and T waves indicate renewal of the ventricle.

Even though electrodes are used to measure electrical activity in the heart, for patients an ECG machine test is painless. However, most doctors recommend that patients avoid drinking cold water right before the test, since it can cause changes in the heart’s T-wave.

In summary, an EKG machine is a helpful tool to help doctors assess their patients’ overall heart health and determine whether chest pains are caused by heart disease.

In order for the heart to effectively pump blood through our bodies, an electrical system of impulses must be working properly.

An EKG machine can measure the efficiency of the heart’s electrical impulses, but some wonder how the heart’s electrical conduction system works in the first place. Here is a brief overview:

Here is what is required for the heart to pump effectively:

* Substantial delay between atrial and ventricular activity: This “delay” between impulses allows the atria (or upper chambers) to completely empty their contents into the lower chambers, or ventricles. If the two chambers were to contract simultaneously, this would result in inefficient filling or back flow. In order to maintain this delay, the atria are electrically isolated from the ventricles.
* Coordinated ventricular cell contraction must be present. In order to maximize systolic pressure, forcing the blood through the body, all ventricular cells must work in concert. This contraction, or depolarization process, squeezes blood in one direction, toward the exit of the heart, because the ventricular cells contact simultaneously.
* After contracting, the heart muscle needs to relax in order to fill up again. Any sustained contraction of the heart muscle, without the necessary relaxation, would be fatal.

An EKG machine can be used to measure the effectiveness of the heart’s electrical system, and provide an early diagnosis of any problems.

Because the cardiac muscle has some unique properties from other muscles in the body, it is important to monitor the rhythms and impulses of the heart on a regular basis, particularly if the patient suffers from hypertension, high cholesterol, diabetes, habitual smoking, or has a family history of heart disease. Maintaining the health of the heart’s electrical rhythms through regular EKG machine testing can be the best preventive medicine for high risk or elderly patients.

Many physicians are too busy to spend a lot of time looking for the best buys on medical equipment for their offices. One key piece of equipment is an EKG machine. If your existing machine is on its last legs, you may be tempted to work with a local rep to replace it, but is that really the best deal you can get?

Most reps that specialize in basic medical supplies do not have enough expertise with high-tech equipment like EKG machines to help you make the smartest choice, nor do they have access to the best deals available. Most reps get incentives to promote certain machines, but the one they are pushing you to buy may not be the right one for your practice.

While your medical supplier may feel entitled to your business, when it’s time to purchase an EKG machine, it makes sense to explore other purchasing options.

Before deciding on a new EKG machine for your office, it pays to shop around. Take the time to shop the internet to find the best price, and you may be surprised at the level of service you will get online. Most EKG manufacturers offer authorized service representatives, and are likely to have one in your area. Some of these manufacturers and online stores will even offer to train your office staff on the new machine. In addition, the manufacturer usually handles all warranty and service issues anyway, so you can work directly with them on any repairs.

When choosing a new EKG machine, make sure you look for one that meets all your needs. It may make sense to consult with your nursing staff prior to choosing a machine since they will be more familiar with its operation and maintenance. They will also know which features to look for, such as paper size, keyboard functionality, screen size, and computer compatibility, and may even know which make and model would work best for your office.

Medical researchers estimate that up to 35 percent of all Americans suffer at least one episode of Syncope during their lifetime. What is Syncope, you may ask? It is a sudden loss of consciousness, which starts out as light-headedness, weakness and dizziness. While recovery is quick, the signs of onset are unpredictable, which can impair Syncope sufferer’s quality of life.

Since symptoms most often occur when a person’s blood pressure suddenly drops, it is believed that cardiac syncope is the result of a heart abnormality, such as arrhythmia, valve disease, or a blockage.

While Syncope can also be caused by intense anxiety, dehydration, hunger, alcohol and drug use, or other medical conditions, about 20 percent of all cases are heart related. When heart problems are suspected, patients undergo EKG and exercise stress tests and will often wear a 24-hour monitor to record heart rhythms over longer periods of time.

Earlier this year, the FDA approved a tool, known as the Sleuth AT Cardiac Monitoring System, which can help physicians diagnose Syncope. The Sleuth is actually a small EKG recorder, which is smaller than a half-dollar. It is implanted beneath the skin in the upper left chest, and measures the electrical activity of the heart. The recorded information is then stored and retrieved on a Personal Diagnostic Manager, which is a small recorder that can be carried in a handbag or pocket.

Traditional implantable EKG recording devices store information for later retrieval at the doctor’s office, or require manual downloading on a home computer. But the Sleuth makes use of Bluetooth technology to transmit data to a patient’s home base station. From there, the information is transmitted to a monitoring center which is staffed by cardiac technicians, where doctors can access it through a secure web site. Using the Sleuth EKG monitor can assure a patient that their doctor will be alerted immediately of any serious problems.

EKG Machines are a very important piece of technology, and should be found in any good physician’s office or hospital. Also known as the electrocardiogram machine, EKG machines offer a non-invasive way to diagnose a wide array of heart conditions. EKG Machines can even point out a heart attack when it is happening.

However, while a patient is on his or her way to the hospital in an ambulance, an “ambulance monitor” will go a long way towards saving the lives of heart attack victims. Thanks to the ambulance monitor being installed in most EMT units, patients headed to the hospital will get faster treatment for heart attacks until they arrive at the hospital.

According to the Courier-Journal in Louisville, KY, several paramedics from the Clark County and New Albany EMS departments were trained to operate this device, which can send real-time EKG data to the hospital while the patient it still in the ambulance.

The point of these mobile EKG devices is to save the heart muscle. The more time that can be shaved off of the time it takes for the patient to arrive in the catheterization lab, the more the heart muscle can be spared from damage.

The new equipment is the Lifepak 12 defibrillator/monitor, which has 12 leads that send signals about a patient’s heart condition directly from the ambulance to the hospital. While the ambulance is still in transit, information received by the hospital ER staff can allow them to prepare appropriately to care for the patient as soon as they arrive. It also eliminates the need for doctors to perform an EKG test once the patient arrives.

As a result of new ambulance monitors, ER doctors hope to shave the amount of lifesaving time from the typical 90 minute “door to balloon” standard down to 60 minutes. When treatment time is shortened, the expectation for surviving a heart trauma goes up significantly, and damage is markedly decreased.
