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 ...

The correct diagnosis is sinus rhythm, LVH, and normal T waves (Figure 2). The ECG shows a normal P wave (+) before each QRS complex with a stable and normal PR interval and a stable PP interval 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 ...

An electrocardiogram, or ECG, is a standard test that records your heart’s electrical activity – offering a quick and painless way to identify irregular heart rhythms and other potential issues. But ...

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 ...
