What is ECG?

ECG test is the most commonly performed heart. This is because the ECG is a useful tool to monitor various cardiac anomalies; ECG machines are available in most medical services, and the test is easy, safe and free.

How ECG?

You own panels and 10 electrodes (or connections) are attached to the arms, legs and chest.The electrodes detect electrical impulses generated by the heart, and put them in ECG car. The machine produces a calendar electrocardiogram (ECG detection) of cardiac electrical impulses.The potential of these electrodes. Test takes less than 5 minutes to run.

What information can be obtained from the ECG?

From the ECG tracing, the following information can be determined:the heart ratethe heart rhythmwhether there are “conduction abnormalities” (abnormalities i

n how the electrical impulse spreads across the heart)whether there has been a prior heart attackwhether there may be coronary artery diseasewhether the heart muscle has become abnormally thickenedAll the features that may be important. Tests if the ECG shows a heart attack or coronary heart disease is probably more common to determine the nature of the problem and decide on th

e ideal treatment. (Located on the tests often stress tests and / or cardiac catheterization.) If the heart muscle thickness, according to echocardiography is often explore the possibility of valve disease or other structural abnormalities. Possible changes in the electrical model of information EKG cause fainting (syncopee), or may indicate the disease.

What are the limits of ECG?

ECG shows the heart rate and rhythm, but during the time it took an electrocardiogram. If this heart rhythm disorder, is now intermittent, ECG, which may lose them. Ambulatory monitoring is necessary to record transient arrhythmias.
ECG can often be normal or nearly normal in patients with heart disease or other forms of coronary heart disease (a false negative.)
Many of the anomalies "that appear in the ECG showed no medical value after a thorough evaluation of (false positive).
