WebThe record of the electrical signal is called an electrocardiogram (ECG). You can infer the heartís mechanical activity from the ECG. The electrical events of the heart are usually recorded on the ECG as a pattern of a baseline broken by a P wave, a QRS complex, and a T wave. The baseline (isoelectric line) is a straight line on the ECG.

WebThe QRS complex may be R alone, QS (no R), QR (no S), RS (no Q), or RSR ′, depending on the ECG lead, vector, and presence of heart disorders. Normally, the QRS interval is 0.07 to 0.10 second. An interval of 0.10 to 0.11 second is considered incomplete bundle branch block or a nonspecific intraventricular conduction delay, depending on QRS ... WebJan 24, 2024 · An electrocardiogram, abbreviated as ECG or EKG, is a measurement of the electrical activity of the heart during the cardiac cycle and can be used to identify if there are any issues with the normal functioning of the heart.
