The rhythm is either sinus rhythm or not sinus rhythm. Sinus rhythm refers to the origination of the electrical activity coming from the sinus node — also known as the sinoatrial node, or SA node.

Mayo Clinic researchers trained artificial intelligence to pick up subtle differences in electrocardiograph readings to diagnose atrial fibrillation with 90% accuracy. Artificial intelligence (AI) can ...

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 ...

When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

An artificial intelligence (AI) model may identify patients with intermittent atrial fibrillation (AF), even when performed during normal sinus rhythm, in a little as 10 seconds, a new study suggests.

Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...

Chargers head coach Jim Harbaugh shared some more information about the health issue that sent him to the locker room during the first half of Sunday’s win over the Broncos. Harbaugh told the CBS ...

Atrial flutter is a type of irregular heartbeat, or an arrhythmia. It causes your heart to beat too fast. Atrial flutter doesn't always have symptoms, but it can sometimes have serious consequences if ...
