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.

Description

Technical field [0001] The invention relates to a myocardial infarction monitoring instrument, in particular to a monitoring device for monitoring heart disease patients and alarming due to bradycardia or sudden arrest caused by myocardial infarction. technical background [0002] For a long time, heart disease patients have not been monitored in time at home, especially at night when the heartbeat or sudden arrest caused by myocardial infarction cannot be noticed by family members in time, which may cause the death of the patient due to lack of rescue. Contents of the invention [0003] The purpose of the present invention is to provide a monitor for heart disease patients to alarm due to bradycardia or sudden arrest caused by myocardial infarction. [0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve the technical problem is: a myocardial infarction monitor is composed of a sensor amplification and sha...
