A new study has linked prolonged P-wave duration to increased risk for sudden cardiac death (SCD), independent of cardiovascular risk factors and atrial fibrillation. 1 This suggests P-wave duration ...
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 ...
The diagnosis is normal sinus rhythm, atrial bigeminy, first-degree atrioventricular (AV) block (prolonged AV conduction), and right bundle branch block (RBBB). The rhythm is slightly irregular, with ...
A first-degree AV node block occurs when conduction through the AV node is slowed, thus delaying the time it takes for the action potential to travel from the SA node, through the AV node, and to the ...
The ECG findings of hyperkalemia change as the potassium level increases. From earliest to latest, the ECG findings include: Peaked T waves best seen in the precordial leads, shortened QT interval and ...
