A pacemaker may be needed to relieve symptoms when no reversible cause — i.e. AV blocking medications or electrolyte disturbances — is found. The strip below shows a junctional rhythm with ...

Resetting of a cardiac rhythm can be easily understood if one compares what is seen in the electrocardiogram (ECG) of a patient with a ventricular pacemaker after a ventricular premature ...

A junctional rhythm occurs when the sinoatrial node (SA node) is not able to generate an action potential and the atrioventricular node (AV node) acts as the main pacemaker of the heart.

Prospective studies of symptom-rhythm correlation in bradyarrhythmic disorders are difficult. This is the first series (albeit retrospective) that demonstrates an association between falls and AVB ...
