Programmable multi-site cardiac stimulator

摘要

Stimulation units (30,32) connected to ventricular (22,24) and auricular (26,28) heart locations may be controlled for ventricular unit (30) by selector circuits (34,36), and output signals (VD,VG) activate corresponding transistors (40,46) and charge capacitors (44,48) to produce signals at either or both ventricular sites (23,24) as required. Same technique is applied to auricular stimulator.
