Description

technical field [0001] The invention relates to the field of data transmission, in particular to an electrocardiographic signal acquisition device and electrocardiographic equipment. Background technique [0002] As people pay more and more attention to health, more and more portable ECG devices have entered the family. A portable ECG device is a device that facilitates the user to perform heart examinations at home. Usually, the electrocardiographic equipment uses electrocardiographic lead wires or metal electrodes to collect electrocardiographic signals, and transmits signals through bluetooth. [0003] Wherein, the ECG lead line is used to collect the ECG signal, and the ECG electrode sheet needs to be buckled with the ECG lead line.

AI Technical Summary

Problems solved by technology

[0003] Among them, the ECG lead line is used to collect ECG signals, and the ECG electrode sheet needs to be buckled with the ECG lead line. Since the ECG electrode sheet can only be used once, the implementation cost is high.

The method of collecting ECG signals with metal electrodes is convenient to collect the signal of lead I, but it is difficult to collect the signal of lead II or other leads. Especially, for thin users, because the signal of lead I is relatively weak, use The effect of the ECG signal collected by the metal electrode is poor, and the adaptability of the ECG signal acquisition is poor

Furthermore, due to the large amount of data of the ECG signal, Bluetooth is always in the data transmission state during the transmission process, and the power consumption is high; at the same time, the current Bluetooth technology pairing is cumbersome and easy to lose packets, and the efficiency of data transmission is low and the accuracy is poor.
