Atrial fibrillation occurs when action potentials fire very rapidly within the pulmonary veins or atrium in a chaotic manner. The result is a very fast atrial rate — about 400 to 600 beats per minute.

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 ...

Some doctors are testing a new device that could make life a bit easier for people with a common heart problem. This has the potential to help a lot of people. Testing is underway to see if a new ...

Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial rate in ...

An artificial intelligence (AI) model has been found to identify patients with intermittent atrial fibrillation even when performed during normal rhythm using a quick and non-invasive 10 second test, ...

Lead-I electrocardiogram (ECG) devices can be used in primary care to help detect atrial fibrillation in people presenting with signs or symptoms of the condition, who have an irregular pulse on ...

The lead-I electrocardiogram (ECG) devices were assessed when they were used in addition to 12‑lead ECGs. Clinical experts advised that a 12‑lead ECG would still be used after lead-I ECGs to identify ...
