PURPOSE: To continuously monitor ECG data and selectively record them by sampling ECG signal waveform by use of a pair of skin electrodes, monitoring the voltage during it, and detecting the pulse on the basis of an ICDM (cardioveter/fibrillation removing monitor) having characteristic amplitude and width. CONSTITUTION: An ADC 22 (sampling means) and a RAM 16 (recording means) generate an ECG data record over one continuously elapsed scheduled time width by the control of a scroll memory buffer having a finite depth within the RAM 16 for recording ECG data. An ICDM pulse detector 20b connected to electrodes 18a, 18b detects the ICDM pulse generated by a buried ICDM and generates a TRIGGERF-signal by generating a pulse satisfying standards of scheduled amplitude and frequency. According to it, a microcontroller 12 interrupts the recording of ECG data to a buffer by the recording means 16 by the end of an elapsed time. |
