Originate from the AV node. The AV node fires before the sinusnode. The ECG shows a QRS complex with a comparable morphology as during sinus rhythm as these extra beats are conducted further through the normal conduction system. When the extra follows very soon after the earlier one, [[aberrant conduction]] can occur. | Originate from the AV node. The AV node fires before the sinusnode.

The extra beat does not have a p-wave in front of it. Sometimes an inverted p-wave can be seen in or at the end of the QRS complex. | The extra beat does not have a p-wave in front of it. Sometimes an inverted p-wave can be seen in or at the end of the QRS complex. | ||
