Cardiac function measurement and evaluation device based on thorax impedance

摘要

Provided is a cardiac function measuring and evaluating apparatus for measuring and evaluating cardiac functions of patients with atrial fibrillation and sinus arrhythmia from thorax impedance data and electrocardiogram data. By creating a two-dimensional scatter diagram plotting (dZ / dt) min value and the corresponding preceding RR interval (RR1), etc., obtained by thoracic impedance measurement, the cardiac function status of patients with atrial fibrillation and sinus arrhythmia However, it can be evaluated visually and easily. The measurement and evaluation apparatus of the present invention can provide very useful information for objectively judging diagnosis of heart disease, selection of therapeutic agents, etc., because the patient can be easily and repeatedly examined with less physical burden. .
