A pacemaker is a small electrically charged device, which is used to treat ARRHYTHMIAS [ah-RITH-me-ahs].
This device senses hearts irregular, slow or fast beating. It sends a signal to the heart, which makes the heart to beat at the correct pace. The doctor places the pacemaker in the chest or abdomen to control this abnormal heart rhythm.
Pacemakers are used to treat the patients with the problem of the heart called Arrhythmias.
Arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow or with an irregular rhythm.
Pacemaker treats two types of Arrhythmias -:
- Tachycardia -: [TAK-ih-KAR-de-ah] in this problem of heart, the heart beats too fast.
- Bradycardia -: [bray-de-KAR-de-ah] in this the heart that beats too slow.
There is one more type of pacemaker- Biventricular. This is a special type of pacemaker or bivent. A bivent helps in the problem known as Cardiac resynchronization therapy (CRT). Bivent makes the two sides of the heartbeat in sync.
