Heart-synchronous blood circulation support system, control method, and heart-synchronous electrical stimulation device

摘要

The present invention relates to a blood circulation assist system that hardly causes complications and does not adversely affect a self-tuning cardiac contraction / dilation function, a control method thereof, and an electrical stimulation device. An electrical stimulation device (100) that outputs an electrical signal that is a pulse wave to at least the lower leg of the human body (P), and an electrocardiographic data acquisition device (200) that continuously acquires an electrocardiographic waveform from the human body (P). And an electrocardiogram data analysis device (300) for analyzing an electrocardiogram waveform acquired by the electrocardiogram data acquisition device (200) and determining an output timing of the electrical signal output from the electrical stimulation device (100). The electrocardiogram data analysis device (300) determines a timing delayed by a predetermined time from the R wave included in the electrocardiographic waveform as the output timing, and the predetermined time is a period of the R wave. This is a time obtained by multiplying the period T by 0.075 to 0.35.
