As a medical professional with expertise in cardiology, I can explain what ECG test results represent. An electrocardiogram (EKG) is a crucial diagnostic tool that records the electrical activity of the heart. The test is noninvasive and provides valuable information about the heart's function, including the rate of heartbeats, the rhythm, and the way electrical impulses are conducted through the heart chambers. ECG test results are interpreted by healthcare professionals to identify any abnormalities that may indicate a variety of cardiac conditions. These can range from arrhythmias, such as atrial fibrillation or ventricular tachycardia, to signs of heart damage due to a previous heart attack, or the presence of heart disease. However, it's important to note that an EKG abnormality is not always a cause for concern. Sometimes, what appears to be an abnormality can be a normal variation in an individual's heart rhythm that does not affect their health. In summary, ECG test results are a detailed report of the heart's electrical activity, which can help in diagnosing and managing heart-related conditions. However, the interpretation of these results requires medical expertise to determine whether any observed abnormalities are clinically significant. read more >>

An electrocardiogram (EKG) measures your heart's electrical activity. This noninvasive test can measure many aspects, from how fast the heart beats to how well its chambers conduct electrical energy. ...
