In 2018, in 1 month, the 'Chinese cardiovascular disease report 2017' issued by the national cardiovascular center shows that the death rate of cardiovascular diseases in China accounts for more than 40% of the death rate of resident diseases, is higher than that of tumors and other diseases, and is the leading cause of death of urban and rural residents. And the cardiovascular diseases show obvious sex difference, the cardiovascular diseases have more serious harm to women, and the death rate of the cardiovascular diseases exceeds 245/10 ten thousand. Within 1 year after a heart attack, 42% of female patients will be lost, more than doubling the mortality rate (20%) of male patients, and therefore greater attention should be paid to cardiovascular disease prevention in women.

For patients with cardiovascular disease or potential patients, prevention, diagnosis and detection of disease is generally performed by Electrocardiogram (EDG). The long-term effective electrocardio monitoring can play a great role in preventing and early diagnosing cardiovascular diseases. The electrocardio-electrode is an important component of the electrocardio-acquisition equipment. And can be divided into wet electrodes, fabric electrodes and capacitive coupling electrodes by principle. The wet electrode needs to be coated with conductive adhesive on the skin to reduce contact resistance, has the characteristics of complex preparation, skin irritation and the like, and is commonly used in the field of professional medical treatment. The fabric electrode is contacted with the skin to transmit electrocardiosignals, conductive adhesive is not needed, and the electrocardiosignals are subjected to error caused by body movement. The capacitive coupling electrode does not need to be in contact with the skin, but extracts the electrocardiosignals through the coupling capacitance formed between the capacitive coupling electrode and the skin, but the signal quality is relatively poor. The capacitive coupling electrode is similar to the fabric electrode in use convenience, and is superior to the wet electrode. In terms of quality of electrocardiosignals, the wet electrode is superior to a fabric electrode, and the fabric electrode is superior to a capacitive coupling electrode.

According to the number of the electrocardio channels monitored by the electrocardio monitoring equipment, the electrocardio channels can be divided into single-lead equipment and multi-lead equipment. Generally, the more the number of channels of the electrocardio monitoring is, the better the electrocardio monitoring quality is.

At present, no electrocardiogram monitoring equipment which is more suitable for women is designed due to higher risk of cardiovascular diseases of women in the research and development of the electrocardiogram monitoring equipment at home and abroad. Nor does it achieve a good combination of ease of use and signal quality in terms of use. Therefore, a multi-lead electrocardiographic monitoring device which meets the requirements of female characteristics in terms of convenience in use and signal quality is urgently needed.
