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 ...
In myocardial excitation, the delay between the excitation of the atria and ventricles is determined by the sum of atrial and atrioventricular nodal conduction. This delay, measured in milliseconds, ...
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 ...
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 ...
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 ...
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 ...
