Abstract
The invention discloses a miocardial infarction monitor which consists of a sensing amplifying shaping circuit, a frequency/voltage conversion circuit and an audio oscillation alarming circuit. The sensing amplifying shaping circuit comprises a piezoceramics, two inverters, two resistances and an LED; the frequency/voltage conversion circuit comprises a 555 time base integrated circuit which forms a monostabillity delay circuit together with a resistance, a capacitance and a trigger dynatron. The audio oscillation alarming circuit and an oscillation clearance are controlled by the PWL or the pulse of the output end of the 555 time base integrated circuit. When a cardiac rate is faster than 48, the miocardial infarction monitor does not alarm, but the LED and the cardiac rate twinkle and display synchronously; when the cardiac rate is slower than 48, the miocardial infarction monitor controls the clearance for alarming; the clearance rate and the cardiac rate are synchronous; when the cardiac rate suddenly stops, the miocardial infarction monitor ceaselessly and continuously alarms.
