A 92-year-old man at Medanta Medicity Hospital implanted the world`s smallest pacemaker which is one of the first hospitals in the country to such a heart device said the doctors on Thursday.

This pacemaker is for the patients with bradycardia which is characterised by slow or irregular heart rhythm that is less than 60 beats per minute.

The US Food and Drug Administration recently approved the Micra Transcatheter Pacing System (TPS) which is a new type of heart device that provides most advanced pacing technology at one-tenth size of a traditional pacemaker.

Balbir Singh, Chairman of Cardiac Electrophysiology and Pacing Section also a senior Cardiologist in sector 38. The heart is unable to pump oxygen-rich blood that is enough to the body during exercise will cause dizziness, fatigue, shortness of breath or fainting spells in patients suffering from bradycardia.

This pacemaker is small enough to be delivered through a catheter and implanted into heart directly with small tines or prongs with a safe alternative to conventional pacemakers with no complications.

“Latest innovation in pacemaker technology coupled with minimally invasive procedure increases the benefit to the patient manifold. Not only is Micra TPS device MRI compatible, it also does not have wires like other traditional pacemakers which reduces the risks of infections caused due to wires,” Singh said.

He added: “It’s a keyhole procedure which makes it cosmetically viable and leaves no visible sign of a medical device under the skin.”
