The latest research shows that both HR and HRV will change under contextual and cued fear conditioning (contextual and cued fear conditioning), but when retrieving contextual and cued fear memories, compared with HR, the expression of HRV for memory and emotional responses are more sensitive and significant (Liu J, Wei W, Kuang H, Zhao F, Tsien JZ(2013) Chan

Example Embodiment

[0031] With reference to the following specific embodiments and drawings, the present invention will be further described in detail, and the protection content of the present invention is not limited to the following embodiments. Without departing from the spirit and scope of the inventive concept, changes and advantages that can be imagined by those skilled in the art are all included in the present invention, and the appended claims are the protection scope.

[0032] Such as figure 2 As shown, the polygraph device based on heart rate variability analysis of the present invention includes: a heartbeat collection device 1, an analysis device 2 and a display device 3.

[0033] The heartbeat acquisition device 1 is contacted or non-contacted with the subject during the test, and is used to collect the heartbeat signal of the subject in real time and transmit it to the analysis device 2. The heartbeat signal includes an electrocardiogram signal or a pulse signal.

[0034] The analysis...

Abstract

The invention discloses a heart rate variability analysis based lie detection method and lie detection device. The heart rate variability analysis based lie detection method comprises collecting heartbeat signals of a tester in real time during the integral testing process; obtaining a time series of heartbeat (RR) intervals according to the heartbeat signals; dividing the RR interval time series into a plurality of sub-series according to the time interval of a conversion before a test, the mentality purification and a formal test; comparing character information of the sub-series and judging whether the tester lies or not with time domains and frequency domain analysis for calculating the HRV (Heart Rate Variability) of the sub-series serving as the character information. The heart rate variability analysis based lie detection method is reliable, strong in practical operability and high in lie detection accuracy.

Description

technical field [0001] The invention relates to polygraph technology, in particular to a polygraph method and polygraph device based on heart rate variation analysis. Background technique [0002] At present, the most widely used and mature polygraph technology in the judicial field is the multi-channel psychological test technology. Physiological response map, and judge whether the subject is lying or not. In the long-term psychological test research and practical application, commonly used physiological indicators include skin electricity, respiration, heart rate (HR) and blood pressure. In the application of the (CQT) method, the peak height ratio is used as the main evaluation method for the post-test evaluation chart (skin electricity); in the application of the direct guideline method (MGQT), the evaluation is carried out by measuring the positive rate (PFC) of the skin electricity related problems . However, existing studies have shown that even under strict contro...
