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 ...
The PR interval is the time from the beginning of the P wave (atrial depolarization) to the beginning of the QRS complex (ventricular depolarization). The normal PR interval measures 0.12-0.20 seconds ...
June 23, 2009 (Boston, Massachusetts) — Prolongation of the PR interval in the ambulatory setting is associated with increased risks of atrial fibrillation, pacemaker implantation, and all-cause ...
Fabry's disease is a rare, X-linked disorder characterized by subnormal or absent activity of the lysosomal hydrolase α-galactosidase A. A deficiency of α-galactosidase A leads to progressive ...
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 ...
