摘要：
An apparatus for non-invasion heart monitoring includes electrocardiogram measuring means (1) for measuring electrocardiograms, pulse wave measuring means (2) for measuring pulse waves, and a CPU (30) for processing electrocardiogram signals derived from the electrocardiogram measuring means (1) and pulse wave signals derived from the pulse-wave measuring means (2). The CPU (30) detects the amplitudes of the pulse waves corresponding to the R waves of the cardiogram and the pulse wave propagation times, and computes a ratio (Nr/N) of the heart rate N and the heart rate Nr exclusive of the heart beats of wave deficits.
