Pacemaker for stimulating a heart has a stimulation unit emitting electric impulses to stimulate bodily tissue and an evaluatory unit to record electric signals with these impulses and assess success levels of stimulation.

摘要

A pacemaker (10) has a bipolar electrode wire (12) connected to it and designed to be inserted into a human heart ventricle. The electrode wire has annular (14) and point (16) electrodes connected by two electric wires (18,20) to the pacemaker, to a stimulation device (22) and a detection unit (24) connected to the annular and point electrodes in order to record electric signals for the heart.
