Device Management for Rhythm Disorders
Pacemaker, ICD, and CRT implantation and follow-up.
Beyond pacemakers, some rhythm disorders need more advanced devices: an ICD (implantable cardioverter-defibrillator) that can detect and correct a dangerously fast rhythm automatically, or CRT (cardiac resynchronization therapy) for hearts where the two lower chambers beat out of sync. We manage the full lifecycle of these devices — implantation, programming, and regular follow-up checks to confirm the device is working exactly as it should.
Types of Device Management for Rhythm Disorders
ICD (Implantable Cardioverter-Defibrillator)
Continuously monitors heart rhythm and delivers a corrective shock automatically if it detects a life-threatening fast rhythm — for patients at risk of sudden cardiac arrest.
CRT-P
A resynchronization device (pacing only, no defibrillator) for heart failure patients whose chambers beat out of sync.
CRT-D
Combines resynchronization pacing with defibrillator protection — for heart failure patients who are also at risk of dangerous fast rhythms.
Frequently asked questions
What's the difference between an ICD and a pacemaker?+
A pacemaker corrects a heart rate that's too slow. An ICD monitors for dangerously fast, life-threatening rhythms and delivers a corrective shock automatically when needed.
How often do I need follow-up checks after getting an ICD or CRT?+
Typically every 3-6 months, or as advised by your cardiologist, to confirm the device is functioning correctly and check battery status.
Will an ICD shock be painful if it activates?+
A defibrillation shock can be felt strongly but happens only in a genuine life-threatening rhythm emergency, and it's designed to correct that rhythm immediately.
