Electrocardiogram interpretation and clinical applications
Currently there are different types of tests to study the behavior of the heart and monitor it. These tests are extremely important, because let us know in time if the heart is failing or has a problem. And because of that, today we submit to treatment or surgery to correct them when they are still small and manageable, before our life is at risk. The electrocardiogram, ECG or EKG, is one of those tests.
Electrocardiogram
The electrocardiogram (ECG / EKG) is the graph obtained with the electrocardiograph to measure the heart's electrical activity as a continuous graphic tape. It also helps to know the duration of the cardiac cycle. It is the main instrument for cardiac electrophysiology and has a significant role in screening and diagnosis of cardiovascular diseases, metabolic disorders and predisposition to sudden cardiac death (Daja, Reljin, Reljin, 2001). The ECG has the advantage of being a medical procedure with results available immediately, which is noninvasive and is inexpensive.
