An electrocardiogram (ECG) is a test that measures the electrical activity of the heart. It is used to diagnose a variety of heart conditions, including arrhythmias, heart attacks, and cardiomyopathy. An ECG report is a printout of the ECG tracing, which shows the electrical activity of the heart over time.
ECG reports can be difficult to interpret, but there are a few key things to look for. First, identify the rhythm of the heart. The normal heart rhythm is called sinus rhythm, and it is characterized by a regular, repeating pattern of P waves, QRS complexes, and T waves. Any deviation from this pattern could indicate an arrhythmia.
