1.   Can the right music lower your blood pressure, modify the immune system, lower body temperature and slow heartbeat?

2.   Eventually, the heartbeat and breathing may stop, but even a very slow heartbeat and rate of respiration may maintain vital body functions.

3.   Pacemakers, surgically implanted in the heart, use electricity to correct a slow heartbeat and keep the heart beating at a steady rate.

4.   The doctors have programmed the pacemaker component to speed up an abnormally slow heartbeat if Cheney develops one.

5.   The pacemaker can speed up a slow heartbeat and can deliver an electrical shock to interrupt two kinds of dangerously fast heart rhythm, ventricular tachycardia and ventricular fibrillation.

6.   Pacemakers help patients with slow heartbeats -- a condition known as bradycardia.

7.   A few had an unusually slow heartbeat.
