Multifunctional Pacemaker Lead for Cardiac Energy Harvesting and Pressure Sensing
Advanced Healthcare Materials, 2020Biomedical self‐sustainable energy generation represents a new frontier of power solution for implantable biomedical devices (IMDs), such as cardiac pacemakers. However, almost all reported cardiac energy harvesting designs have not yet reached the stage

Classification of cardiac pacemakers
The Journal of Cardiovascular Nursing, 1991Pacemaker codes were developed to describe cardiac pacemaker function. Familiarity with these codes is essential for nurses caring for the patient with a permanent pacemaker. The article addresses the classification code of the North American Society of Pacing and Electrophysiology and the British Pacing and Electrophysiology Group and its relationship

A transtelephonic system for evaluation of implanted cardiac pacemakers has been developed. Over a 12-month period, 134 units were tested. Of the 28 pacemaker replacements, 26 were due to battery failure and were predicted. All 26 patients were electively admitted for pacemaker replacement.

, 2013 Building high quality and zero defects medical software-based devices is a critical task, and formal modelling techniques can effectively help to achieve this target at the certain level. Formal modelling of a high-confidence medical device, such as that is too much error prone in operating, is an international Grand Challenge in the area of Verified ...

A cardiac pacemaker model is described based on a close approximation of the properties of cardiac pacemaker cells. It is a minimum-parameter model which has a simple relaxation oscillator circuit as its main element. The pacemaker model is analyzed in detail in order to show that its behaviour is similar to that of cardiac pacemaker cells.

To the Editor:— The report by Mullen et al of two cases of cardiac tamponade from ventricular perforation by a transvenous pacemaker ( 203 :142, 1968) brought to mind a bizarre complication from this procedure which occurred last year at the Meadowbrook Hospital, East Meadow, NY. The patient was a 75-year-old man with chronic congestive heart failure

To the Editor.— I would question the medical wisdom of having patients use a magnet at home to change their demand pacemaker to the fixed rate (222:1379, 1972). The first time a physician encounters a ventricular fibrillation in a patient and the patient dies, he is going to be liable not only for wrongful death, but for punitive damages, because of ...
