What we do...


A pacemaker is a small, battery-operated device that senses when your heart is beating too slowly. It then sends a signal to your heart t0 make it beat at the right pace.


If there is an infection in an implanted device or if the leads are malfunctioning, the device and the leads need to be removed. This is called Lead extraction and Device explantation.


An implantable cardioverter-defibrillator (ICD) is a device that detects  and terminates any life-threatening, rapid heartbeat. 


An Electrophysiologic study is done to understand the current circuits in the heart. Abnormal circuits may cause symptoms like sudden palpitations, fainting, giddiness, or tiredness.


A CRTP is a device that helps improve the pumping of the heart  by making all parts of the heart contract simultaneously. A CRTD is a device that has both the functions of a CRTP, and an ICD put together.


RFA stands for Radio Frequency Ablation. It uses radiofrequency energy to get rid of abnormal electric circuits in the heart. Once it is done, you will not experience sudden palpitations and fainting.

Please share your experience with us. We value your feedback as an opportunity to make improvements and take corrective actions where needed. If you are unhappy about any aspect of your care or treatment, please talk to your doctor as he may be able to solve the problem immediately.


Birendra Kumar Sahu

I, Birendra Kumar Sahu from Jamshedpur had a very satisfied experience during my medical treatment at CMC. I visited CMC, during christmas time Dec 22. I had a history of VT and then i thought to get it checked at CMC after I consulted the doctor here at my place. On 20th Dec, I met with Dr. John Roshan Jacob and he advised me to go with ICD implantation. At first i was bit nervous but thanks to Doctor & nursing staff who made me comfortable and explained things repeatedly in detail until i convinced. I was quite happy to discuss the pro & cons of ICD with doctor and supporting nurses. Hats off to them to listen patiently and resolve all queries despite their busy schedule. I think this is the one of USP of CMC. All that talks boosted me & gave me little courage to go for procedure. Now, I am doing well by grace of god and hoping to resume my routine work soon. God bless every one and keep doing good work!!


Rajib Roy Chowdhury

I, Rajib Roy Chowdhury from Bangladesh; had my chance to visit CMC on 12th January 2022. I am an ICD implanted patient. I was sick for a long time from recurrent VT. I received several cardioversion shocks from my device. From August 2021 to December 20211 I suffered more that 30 VTs. Though all of them were terminated by ATP. On 14th Jan. 2022 I met with Dr. John Roshan Jacob. He made a plan to put an end to my sufferings. At first they did CAG then PTCA with two stent, ICD PG change and finally VT ablation. I was so happy for the treatment that I received. I became a die-hard fan of Dr. John and Dr. Sirish. I was amazed to see the patience of Dr. David Chase. I would also like to thank Dr. Anand who implemented the idea of melodious musical fountain in EP cath lab which really boosted my courage during the procedure. Now I am doing well by the grace of Almighty.
CMC is truly a right place for world class cardiovascular treatment with affordable cost by outstanding, accomplished doctors. I am grateful to the entire team.
God bless.
