We have studied aremote monitoring system of artiticial heart-implanted patientusing a personal handy phone system (PHS). Information on motor rotational angle (data:7bits+flag:1bit) and motor current (data:7bits+flag:1bit) of an implantable motor-driven assist pump was fed into a mobile computer for the transmission control outside the body from an implantable controller(16 bit one-chip microcomputer) according to 32 bits command codes from a host computer in a hospital. Each of three pairs of motor current data and motorrotational angle data from inside body were framed to gether with a control code (frame number and parity), and sent through the PH S connected to the mobile computer. The transmitted signals could be fed into a host computer for patient monitoring via a modem in a poor electric wave environment. The host computer calculated pump stroke and pump outflow and motor current based on the information, and showed real time waveforms on a computer display. When the host computer found error frames, the host computer sent the mobile computer a resend message with the broken frame number. This communication protocol contributed to reduce error-data transmission through the PHS.The developed system is useful for monitoring artificial heart-implanted patients
