Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to specific embodiments of the present utility model and corresponding drawings. In the description of the present utility model, it should be noted that the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In the prior art, many smart watches are provided with electrocardiographic monitoring elements, but because the smart watches adopt a scheme of monitoring electrocardiography by a single lead, for example, the electrocardiograph with the single lead only uses one electrode to record electrocardiographic signals, and compared with the electrocardiograph with multiple leads, the electrocardiograph with the single lead provides less information, therefore, the electrocardiograph with the single lead may not provide enough details to evaluate complex heart problems or can not capture specific electrocardiographic abnormalities, such as acute myocardial infarction; furthermore, single-lead electrocardiograms are difficult to provide for a panoramic view of the entire heart, and thus diagnostic accuracy may be limited in certain disease or abnormal situations.
If the real-time electrocardiogram of the heart with multiple angles is accurately monitored, a scheme of multiple leads is needed, but the current equipment for monitoring the real-time electrocardiogram by multiple leads has larger volume and more electrodes, so that the operation difficulty and the using time cost are increased, the carrying is inconvenient, and the application range of the equipment in clinic and daily monitoring is limited; further, the data volume of multi-lead electrocardiographic recordings is typically large, containing more signals and waveforms, requiring a physician to have more expertise and technical skills for interpretation and analysis, and limiting its independent use in certain everyday scenarios.
