First-degree AV block: ECG quiz video

A 23-second clip of the Patient Simulator monitor. The rhythm name is never on the screen: the video asks the question, gives a hint, counts down five seconds and then gives the answer.

Hint

What rhythm is this? Measure from the start of the P wave to the QRS.

Answer

First-degree AV block. Every P wave gets through, just late. The PR interval is longer than 0.2 seconds.
