Atrial rhythm resembles sinusrhythm, but origins from a different atrial focus. It can be recognised by the abnormal configuration of the p-wave. Often the p-wave is negative in AVF, as is seen in the example.

This is part of: Supraventricular Rhythms
Atrial Rhythm
{{{locatieafbeelding}}}
Atrial rate 50-100 bpm
Ventricular rate 1:1
Regularity regular
Origin atrial
P-wave present, but different from sinus rhythm
Effect of adenosine slows down
Example ECG: Atrial rhythm. In this example the sinus node stopped pacing due to ischemia during an atrial infarction. The p-wave is positive in I, negative in III and AVF. The atrial pacemaker is thus situated at the bottom of the right atrium, close to the AV node.

Atrial rhythm resembles sinusrhythm, but origins from a different atrial focus. It can be recognised by the abnormal configuration of the p-wave. Often the p-wave is negative in AVF, as is seen in the example.

Conversion of sinus bradycardia to atrial rhythm is sometimes seen in young patients with sinus bradycardia, as in this example.
