Continuous monitoring of pacemaker activity can provide valuable information to improve patients' follow-up. Concise information is stored in some types of pacemakers, whereas ECG can provide more detailed information, but requires electrodes and cannot be used for continuous monitoring.
for a contactless real-time continuous monitoring of pacemaker pulses and has several potential applications. For each correctly sensed pulse, its occurrence time (timestamp) can be stored in...
Scientists at Northwestern and George Washington universities in the US have developed a wireless, battery-free implantable pacemaker that uses NFC to harvest energy from an external antenna and dissolves after it is no longer needed to control a patient’s heartbeat.
In a previous paper , some of the authors presented an innovative device based on a new methodology to perform contactless, non-invasive monitoring of pacemaker activity. It was based on the detection of the variations of the magnetic induction field caused by the pacemaker current pulses.
Researchers Have Created a Dissolvable Pacemaker The wireless device is biodegradable and might be a safer alternative to temporary pacemakers.
Pacemakers help manage arrhythmias, such as bradycardia (low heart rate), and restore normal blood flow. A leadless pacemaker is a newer type of pacemaker suitable for people with a certain type of heart disease .
Lampert noted that there is already a wireless permanent pacemaker that doctors can implant via catheter — a thin tube that is threaded into a vein to reach the heart without open surgery.
It connects wirelessly to an external antenna, using the same technology that allow smartphones to make contactless payments, Rogers explained. At this point, the pacemaker has been tested in several animal models, as described in the report published June 28 in the journal Nature Biotechnology.
A contactless electric vehicle battery charger was used to validate the theory by comparing the measured and calculated operational frequency and power transfer. ... A pacemaker is described which ...
