A study by an Indian-American researcher in New York City shows a new wireless pacemaker which is safer, smaller and can be inserted without a surgery.
The new device is faster, smaller than a triple-A battery and easier to implant compared to the traditional pacemakers.
Traditional pacemakers have some complications attached with them, said Vivek Y Reddy, MD, lead author of the study and director of Cardiac Arrhythmia Service at Mount Sinai Hospital in New York City.
The traditional ones contain leads which can break or lead to vein blockage. The pulse generator implanted under the skin of the chest can cause infections. Wires to the heart can also pose problems at times. Leads can break, dislodge or contribute to a vein blockage.
But the new device does not contain leads and the pulse generator is fixed within the unit in the heart. One does not even need a surgery to place the device. It is placed with the help of a catheter.
But the new pacemaker can be used only for those patients who need single-chamber pacing, which amounts to around 20 per cent to 30 per cent of US and European patients who need pacemakers. Patients who require dual-chamber pacing cannot opt for the new device and they will still have to use the traditional pacemakers, said Reddy.
Researchers also said that the new device is free of any complications arising from wire malfunctions.
