A simple method for producing a pacemaker with low cost that works in modes: VOO, AOO

This paper presents a method for designing and producing a temporary cardiac pacemaker device to cure cardiac arrhythmia. To produce this device Schmitt Trigger Circuit was used to control rate, Op-Amp comparator circuit to regulate pulse width, monostable to regulate pace refractory period and sense refractory period, and it is worthy to mention hat pacemaker works in VOO and AOO. Parameters of this device were measured by employing Sigmapace 1000.
