WebA typical pacemaker has 2 electrodes – one in the right atrium and one in the right ventricle. If the myocardium produces its own electrical discharge (intrinsic beat), the pacer will turn itself off and not produce a pacer spike; this is called sensing.. If a pacer possesses a sensor, this is called a demand pacemaker, i.e. it will only discharge if a long pause occurs. WebAV sequential pacing AV sequential pacing will present with a regular rhythm.
