also known as third-degree heart block or complete heart block, occurs when no action potentials conduct through the AV node. This results in the P waves (atrial depolarizations) being completely ...

The deployment of AI for direct-to-physician ECG reporting has far-reaching implications for healthcare systems worldwide.

In fact, up to 60% of athletes demonstrate ECG changes (in isolation or in combination) such as sinus bradycardia, sinus arrhythmia, first-degree atrioventricular (AV) block, early repolarisation, ...

A first-degree, or 1 st degree, AV block is indicated on the ECG by a prolonged PR interval, as seen below. Recall that the P wave indicates atrial depolarization, initiated by firing of the SA node.
