Prolonged periods of lack of sinus node activity and often lack of atrioventricular node activity as well, leading to slow heart rate (bradycardia) may alternate with sudden onset of very fast heart rate originating in the ventricles, causing the heart to beat ineffectively (known as “paroxysmal ventricular tachycardia”), producing ...

The usual indications for a pacemaker are symptomatic heart block (whether congenital or acquired) and arrhythmias such as sick sinus syndrome (bradycardia – tachycardia syndrome). The prognosis in conditions treated with a pacemaker is related to the nature of any underlying heart disease.
Sick sinus syndrome: MedlinePlus Medical Encyclopedia
Sick Sinus Syndrome (SSS), Bradycardia-Tachycardia Syndrome . SSS includes several disorders with accompanying rhythm and pulse disturbances. An alternating pattern of slow and rapid heart rate is common. This disorder can cause dizziness, syncope and life-threatening arrhythmias. Treatment includes medications and pacemakers.

Patients whose SND manifests as sinus bradycardia have a better prognosis than those with tachycardia-bradycardia syndromes. Thromboembolic complications are a significant cause of morbidity and mortality. Tachycardia-bradycardia syndromes are the variants with the most significant stroke risk.
