Method and apparatus for measuring information representative of the dysfunction and abnormal heart

摘要

An apparatus for measuring information indicative of cardiac dysfunction and abnormality includes a processing unit (402) configured to detect a change in amplitude from a signal representative of cardiovascular motion, wherein the processing unit is a cardiac activity. A first waveform that repeats the heart rate is extracted from a signal that represents an electromagnetic phenomenon related to, and a second waveform that repeats the heart rate is extracted from the second signal. The processing device creates timing data representing the time from the reference point of the first waveform belonging to one heartbeat period to the reference point of the second waveform belonging to the same heartbeat period. The processing device measures information representing cardiac dysfunction and abnormality based at least in part on the timing data. [Selection] Figure 4
