Abstract

The invention discloses a multi-conducting-channel synchronous electrocardio signal processing method and an apparatus. The method comprises the following steps: A1, collecting electrocardio signals of each conducting channel respectively and obtaining electrocardio signal data of each conducting channel; B1, calculating a quality judgment guideline of each conducting channel according to the electrocardio signal data; C1, performing optimized conducting channel selection according to the quality judgment guideline; D1, performing QRS wave identification and specification to each single conducting channel or at least to the optimized conducting channel according to the electrocardio signal data; E1, performing a combination judgment to the QRS wave identification and specification result of the optimized conducting channel to form a combination detection result. The invention realizes the tracing of dynamic variation of the quality of signals in a comparatively complicated clinical application environment and the effective extraction of electrocardio signals through dynamic switching of the optimized conducting channels, and finally a reliable analyzing information of the rhythm of heart of a patient can be obtained.

Description

【Technical field】 [0001] The invention relates to electrocardiographic monitoring equipment, in particular to a method and a device for processing multi-lead synchronous electrocardiographic signals in the multi-lead electrocardiographic monitoring equipment. 【Background technique】 [0002] ECG monitoring equipment is one of the most important and basic equipment in the intensive care unit (ICU). It processes the ECG activity from the patient's body, identifies the QRS wave, and performs HR according to the position and type of the QRS wave. Calculation of parameters such as (heart rate), ST (referring to the section between the J point and the starting point of the T wave in the ECG signal) offset and ARR (arrhythmia). [0003] In the past long-term ECG monitoring analysis, the single-lead analysis method is mostly used, and the user selects the required analysis lead, and there is also a method of fixing a specific lead (such as lead II) with a common waveform. In actual ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the analyzed lead is disturbed and the signal quality of other leads is better, the wrong analysis result will still be produced;

[0005] 2. For noise signals, the single-lead signal analysis mostly adopts the noise suppression method, and then performs forced analysis, and the noise suppression method is easy to transform some interference signals into pseudo QRS waves, resulting in subsequent analysis errors;

[0006] 3. When the signal quality of each channel changes dynamically, in order to obtain reliable analysis results, the user needs to switch the analysis leads frequently;

[0007] 4. For some special ECG waveforms, there may be a phenomenon of normalization of ventricular premature beats in some leads, which makes the single-lead analysis method unable to perform corresponding alarms
