Implantable demand pacemaker.
Adams-Stokes seizures can occur in patients with intermittent complete A-V block. The history of a single Adams-Stokes syncopal attack is an indication for intracardiac pacing. Fixed rate pacemakers employed in the presence of intermittent varying degrees of A-V block and sinus rhythm result in recurrent co-acting rhythms of artificial and natural beats (Linenthal and Zoll, 1962). This arrhythm...
متن کاملDesign Overview Of Processor Based Implantable Pacemaker
Implantable pacemaker is a battery operated real time embedded system, which includes software/hardware codesign strategy. As it is placed within the heart by surgery, battery life is an important constraint to extend device lifetime. In this paper, pacemaker’s functionalities like basic pacing, pulse width, refractory period in VOO mode has been realized using ultralow power processor MSP 430F...
متن کاملInterpretation of complex demand pacemaker arrhythmias.
Accurate knowledge ofpacemaker specifications provides the key to the understanding of complex demand pacemaker arrhythmias. This communication describes two examples of complex pacemaker arrhythmias related to the sensing mechanism of normally functioning Medtronic demand pulse generators. Oversensing of atrial voltage generated by an atrial parasystolic focus produced the first arrhythmia. Th...
متن کاملA report on an implantable electronic cardiac pacemaker.
The cardiac pacemaker, although comparatively new, is no longer in an experimental stage. It is now in the armamentarium of medical men and surgeons concerned with treating complete heart-block with Stokes-Adams seizures. Four or five years ago, when the need for such a device became obvious, several centers started working on different types of pacemakers that were reported almost simultaneous...
متن کاملMeasurement and analysis EMC parameters of implantable pacemaker
This paper deals with problematic of Electromagnetic Compatibility of Implantable Pacemaker. The ambient electromagnetic field can negatively influence the pacemaker functionality and also the wireless communication between its programmer and device. Electromagnetic compatibility parameters are tested by direct induction of interference signal to the inputs of cardiac pacemaker according to tec...
