Atrial Bigeminy is a harmless, benign rhythm. It is frequently an incidental finding and is usually asymptomatic. No further cardiac investigations are indicated as most people with this rhythm do not have organic heart disease (although in those with heart disease, it seen).
Rule of bigeminy. When the atrial rhythm is irregular (as in atrial fibrillation or sinus arrythmia) the presence of bigeminy depends on the length of the P-P interval and happens more frequently with a longer interval. As with post PVC pauses, a longer P-P interval leads to a higher chance of re-entrant circuits and thus PVCs.
