Embodiment Construction

[0038] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0039] refer to figure 1 As shown, for the single-arm measurement process of single-lead ECG acquisition, large interference is introduced, which seriously affects the accurate calculation of heart rate and the accurate analysis of heart rhythm. Embodiments of the present invention provide an ECG signal processing method, The method includes:

[0040] Step 100: The measuring device collects ECG signals.

[0041] The measurement device referred to in the embodiment of the present invention is a single-lead ECG collection device. For example, wearable devices etc.

[0042] The measurement equipment collects ECG signals. For example, the user wears a single-lead ECG acquisition equipment, turns on the switch, and the equipment enters the self-inspection stage. If the equipment self-inspection passes, it indicates that the user is wearing it correctly and the equip...

Abstract

An ECG signal processing method and device (700), used to solve the problem that large interference is introduced in the single-arm measurement process of single-lead ECG acquisition, which seriously affects the accurate calculation of heart rate and the accurate analysis of heart rhythm. The method includes: measuring equipment collects ECG signals (100); extracts the kth effective QRS complex of the ECG signal (110), calculates the kth time difference and the (k+1)th time difference (120), and judges the kth Whether the time difference and the (k+1)th time difference is the target time difference (130a, 130b). Therefore, the accuracy of ECG feature extraction is improved, the interference introduced in the single-arm measurement process is greatly eliminated, and the accuracy of heart rate calculation and heart rhythm analysis can be effectively guaranteed.

Description

[0001] This application claims the priority of the CN patent application with the application number 201610974448.2 and the title of the invention "a single-arm ECG measurement method and terminal" submitted to the China Patent Office on November 3, 2016, the entire contents of which are incorporated by reference In this application. technical field [0002] The present invention relates to the field of terminals, in particular to an ECG signal processing method and device. Background technique [0003] Traditional electrocardiograph (ECG) measurement requires cross-cardiac measurement, which limits application scenarios and results in poor user experience. [0004] In the prior art, various portable single-lead ECG acquisition and measurement schemes are proposed. Specifically, single-lead ECG acquisition equipment mostly adopts the measurement method of simulating limb I lead (hands), or simulating chest lead (chest area, across the heart), and these measurement methods a...
