Dual-chamber pacing versus single ventricular pacing has been shown to result in less atrial fibrillation, stroke, and congestive heart failure, but no difference in mortality. Causes of sinus node dysfunction The causes have been discussed in each respective article. Its role is to keep the heart beat steady and regular.

Bradyarrhythmias are well controlled with pacemakers, while tachyarrhythmias respond well to medical therapy. This stops fast heart rhythms from reaching the ventricles and causing problems.
