WebAmerican Heart Association WebFeb 24, 2024 · High-grade AV block is a form of second-degree (incomplete) heart block that can commonly be confused with third-degree (complete) heart block. It occurs when there are two or more consecutively blocked P waves. This conduction disturbance can be particularly dangerous as it can progress to complete heart block.
WebCommon findings Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant.
