A Simple Laboratory Demonstrate Pacemaker
Abstract
A simple pacemaker circuit has been designed, fabricated and tested. The circuit consists of Signal Generator, Amplifier, Filters and Noise reduction circuits. The pulse signals generated from an operational amplifier circuit and fed to monostable 555 timer circuit. The pulses are acquired with Digital Storage Oscilloscope (DSO). The performance of the developed system is evaluated by recording the pulses of people having different heart beats, wave forms recorded are compared with standard pulse wave forms e.g. frequency, amplitude, pulse duration, shape etc. The accuracy of the diagnosis presently depends on the expertise of the physician.
