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 ...

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 ...

The U.S. Federal Aviation Administration (FAA) broadened a standard for normal heart function in pilots because medical evidence showed no symptoms or additional health risk up to the raised threshold ...

A 68-year-old male with morbid obesity and no past medical history comes to the office complaining of fatigue and shortness of breath. He does not feel dizzy and has never passed out. He takes no ...

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 ...

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 ...

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 ...

An electrocardiogram, commonly called an ECG, is one of the most widely used tools for checking heart health. It records the electrical signals that control your heartbeat and can reveal problems such ...
