what do you understand by pacemaker of heart
Answers
Explanation:
A pacemaker is a small but very sophisticated electronic device that is implanted under the skin to help regulate the heartbeat. Specifically, pacemakers are most commonly used to treat several cardiac arrhythmias that produce bradycardia—a heartbeat that is too slow. The heart rhythms that cause bradycardia are sick sinus syndrome and heart block. Pacemakers usually eliminate the symptoms caused by bradycardia including weakness, fatigue, lightheadedness, dizziness, or syncope (loss of consciousness).
In some people who have heart failure, a specialized type of pacemaker can help coordinate the beating of the cardiac chambers—the atria and ventricles. These specialized pacemakers—which are called cardiac resynchronization therapy (CRT) devices—can significantly improve cardiac function and symptoms in many people with heart failure.
