What Is Sick Sinus Syndrome?
5. Bradycardia-Tachycardia Syndrome
Another type of sick sinus syndrome is bradycardia-tachycardia syndrome. The rate at which our heart beats will change according to how much oxygen we need at the time. Despite this, the rate will stay at a fairly steady pace with no sudden changes, except for times when our oxygen demands increase rapidly or we become anxious or excited.
Bradycardia is a condition in which the heart beats too slowly, and tachycardia is a condition in which it beats too quickly. As the name suggests, bradycardia-tachycardia syndrome is both, and the heart will alternate between beating too quickly and too slowly.
