Embodiment Construction

[0028] figure 1 A flow chart of an ECG signal detection method is shown, and the specific process is as follows:

[0029] Step S100 , extracting the signal, and extracting the ECG signal and the sound signal of the subject at the same time. The sound signal is collected while the ECG signal is extracted, the sound signal is continuously collected for 24 hours, the sound signal at each moment is recorded, and the realization is achieved by judging the environmental energy threshold, which usually adopts an adaptive threshold.

[0030] Step S200, ECG signal detection, processing the ECG signal to obtain ECG signal characteristic parameters, and according to the standard limit value, judging whether the ECG signal characteristic parameter in the ECG signal database is within the standard limit value range . If the ECG signal is within the standard limit range, end the ECG signal detection; if the ECG signal is not within the standard limit range, determine whether the sound sig...

Abstract

An electrocardiograph signal detection method comprises the following steps: simultaneously extracting the electrocardiograph signal and the voice signal of the testee; processing the electrocardiograph signal to obtain the characteristic parameter of the electrocardiograph signal and judging whether the characteristic parameter of the electrocardiograph signal is in the range of the standard limit value according to the standard limit value, if so, completing electrocardiograph signal detection, if not, entering into the step of voice signal detection; and processing the voice signal and judging whether the voice signal is abnormal, if not, determining that the characteristic parameter of the electrocardiograph signal is in the range of the standard limit value, if so, ensuring the result that the characteristic parameter of the electrocardiograph signal is not in the range of the standard limit value to be undetermined. During electrocardiograph signal detection, the emotional state of the testee is checked by extracting and recognizing the voice signal, thereby determining the detection result, getting rid of the interference of emotional instability of the testee with the electrocardiograph signal and providing the medium data used for reference in clinical diagnosis.

Description

【Technical field】 [0001] The present invention relates to a medical detection method and device, in particular to an electrocardiographic signal detection method and device. 【Background technique】 [0002] As an important means of monitoring heart disease, ECG signal detection provides a reliable basis for monitoring heart disease. However, when doing ECG signal detection, the subject's ECG signal is easily affected by their emotions and states. Emotions and states such as anger, crying, laughing, wheezing and coughing are all affected. The result of ECG signal detection will lead to the inaccuracy of ECG signal detection result. [0003] Therefore, it is necessary to improve the existing ECG signal detection method, so as to eliminate the disturbance to the ECG signal when the subject is emotionally unstable, and to realize the accurate monitoring of the ECG signal. [Content of the invention] [0004] Based on this, it is necessary to provide an ECG signal detection met...
