Problems solved by technology

When performing this type of operation, stimulation equipment must be used to send stimulation pulses, and two instruments, the electrocardiograph and the stimulator, are used at the same time, which brings great inconvenience to the clinician.
Moreover, if the hospital wants to develop the esophageal cardiac modulation stimulation technology, it must purchase two kinds of equipment, the electrocardiogram machine and the stimulator, which also increases the equipment procurement cost of the hospital.

Abstract

A digital 12-channel electrocardiograph able to record standard 12 human electrocardiac signals in 12 channels, output the irritation signals for regulating esophageal pulse, and record esophageal electrocardiac signal for diagnosing cardiovascular diseases is composed of leads combinant circuit, cardioelectric amplifier, microprocessor, printer, display unit, sound-light alarm unit, keyboard, memory, communication interface LAN, real-time clock circuit, peripheral interfaces and power supply.

Description

【Technical field】 [0001] The invention belongs to the field of medical electronic instruments, and in particular relates to a cardiovascular disease diagnostic instrument capable of recording standard 12-lead human body surface electrocardiographic signals, outputting esophageal modulation stimulation pulses and recording esophageal electrocardiographic signals. 【Background technique】 [0002] Cardiovascular disease is one of the main diseases that threaten human health. The electrocardiograph is mainly used for the diagnosis of cardiovascular diseases such as arrhythmia and the research of the special conduction system of the heart. It is the most basic first-line diagnostic tool in medical and health institutions and is widely used in Various levels of medical hospitals, outpatient clinics, clinics and community medical and health institutions. [0003] Esophageal cardiac pacing stimulation is one of the indispensable and important means in the clinical diagnosis and resea...
