Abstract
A heart stimulating device has the capability of detecting fusion and/or pseudofusion heartbeats by measuring electrical impedance encountered by a delivered stimulation pulse. The device has a pulse generator connected to a lead system for emitting and delivering stimulation pulses, and an impedance measuring arrangement for measuring the impedance. A logic circuit determines that a response by the cardiac tissue to a delivered stimulation pulse includes a fusion or pseudofusion heartbeat if the measured electrical impedance is within a predetermined impedance range, and determines that the response does not include a fusion and/or pseudofusion heartbeat if the measured electrical impedance is outside of the predetermined impedance range.
