Description

technical field [0001] The invention relates to a medical instrument, especially a portable diagnostic and therapeutic instrument capable of cardiac physiological pacing and cardiac program-controlled stimulation. Background technique [0002] At present, the cardiac stimulators used at home and abroad have relatively single functions, and are generally only used in electrophysiological therapy, and there are few changeable stimulation methods, and the price is relatively high. In addition, the volume is relatively large, so it is not convenient for doctors to carry it for outpatient visits. Contents of the invention [0003] The purpose of the present invention is to provide a portable cardiac pacing / program-controlled stimulator with multi-parameter menu selection, which has the characteristics of small size, low manufacturing cost and many practical functions. [0004] The present invention is achieved in the following way: a portable multi-parameter menu selection car...
