Abstract

A simple and low cost ECG simulator is described. The output waveform is a narrow pulse followed by a T-wave which extends to about one-half of the period. This waveform is acceptable by the medical staff and provides to the BMET a simple, calibrated waveform. Four switches control the simulator; (1) power on or off; (2) fixed rates of 60 or 120 BPM; (3) filtered or normal; (4) square wave or pulse. The amplitude is calibrated to 1 mv for a three-lead cable and 0.5 mv steps for use with a five-lead cable. An output of 1.8 volts is available for driving auxiliary equipment. An external light-emitting diode provides visual indication in all modes. A push button switch provides manual testing of respiration modules.
