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 ...

This rhythm strip shows 1:1 conduction of sinus P waves with a normal PR interval at a rate of about 82 beats per minute (RR = 0.72 sec). After the fourth beat there is an isoelectric baseline with no ...

The correct diagnosis is sinus rhythm, second-degree AV block with 2:1 conduction, Mobitz type II (Figure 2). There is a regular rhythm at a rate of 42 beats/min, although the last QRS complex is ...

Artificial intelligence (AI) can detect signs of existing or emerging A-fib in ECGs that exhibit normal sinus rhythm, Mayo Clinic researchers have found. Their retrospective analysis, published online ...

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 ...
