The time from the beginning of the P wave, indicating atrial depolarization, to the beginning of the QRS complex, representing ventricular depolarization, is the PR interval. This represents the time ...
An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes. There are ...
The electrocardiogram (ECG) is a valuable tool for assessing the cardiac conduction system. The measurements routinely obtained with ECG include heart rate, PR interval, QRS duration and the QT ...
