Title:
HEARTBEAT DETECTION METHOD AND HEARTBEAT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/215191
Kind Code:
A1
Abstract:
This heartbeat detection device includes: an index value calculating unit (5) that calculates, for each sampling time, index values from a sampling data string of an ECG waveform of a living body; a threshold value determining unit (6) that compares a threshold value for heartbeat detection with the lower limit of the range being likely as a threshold value derived from the ECG waveform of the living body; a heartbeat time determining unit (7) that determines the sampling time of the peak as a heartbeat time when the threshold value determining unit (6) determines that the threshold value is not less than the lower limit, and detects an index value peak exceeding the threshold value; and a threshold value setting unit (8) that renews the threshold value on the basis of the index value peak exceeding the current threshold value.
