Simple wireless electrocardiogram detecting apparatus

The utility model relates to a simple wireless electrocardiogram detecting apparatus. After an electrocardiogram signal is collected by an electrocardiogram sensing module, the electrocardiogram signal is transmitted through a preamplifier module, a main amplifying module and a filter module in turn, sent to a singlechip to be subjected to A/D(Analog to Digital)conversion and data processing and sent to a miniature wireless serial interface module to be emitted, after the data are received by a wireless data receiving module, the data are sent to a PC host to be processed and displayed, a press key signal is input to the singlechip by a press key module, and a battery module is used for charging each working module. Whole networking is unnecessary to be realized, and the PC host can monitor electrocardiogram signal states of a patient in real time when the patient wears the device and remains in a working state. According to the simple wireless electrocardiogram detecting apparatus, instant use after startup of the apparatus is realized, troubles of network building and the like are eliminated, and the electrocardiogram detection is strong in anti-jamming capability, good in stability, low in cost and convenient in use.
