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 ...
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 R-R interval is the same as the P-P interval plus whatever change there is in the PR interval. In typical AV Wenckebach phenomenon, the PR intervals increase with decreasing increments and the R-R ...
June 24 -- TUESDAY, June 23 (HealthDay News) -- A slight abnormality in an electrocardiogram (EKG), until now thought to be insignificant, can be a warning sign of future cardiac problems and an ...
A common electrocardiogram finding that has largely been considered insignificant may actually signal an increased risk of atrial fibrillation, the future need for a permanent pacemaker and an ...
