Pacemakers are typically used for slow arrhythmias such as sinus bradycardia, sick sinus syndrome, or heart block. An ICD senses the rate of the heartbeat. When the heart rate exceeds a rate programmed into the device, it delivers a small electrical shock to the heart to slow the heart rate. Many newer ICD's can also function as a pacemaker by delivering an electrical signal to regulate a heart rate that is too slow. ICD's are typically used for fast arrhythmias such as ventricular tachycardia.
Surgical ablation is a major surgical procedure requiring general anesthesia.
The chest is opened, exposing the heart. The site of the arrhythmia is located, then destroyed or removed in order to eliminate the arrhythmia. Click here to view the Online Resources page of this Web. Contact Information Copyright 2001 Methodist Health Care System, Houston, Tx. All Rights Reserved.
