ULTRASONIC DIAGNOSTIC EQUIPMENT AND HEART RATE SYNCHRONIZING SIGNAL GENERATOR

摘要

PROBLEM TO BE SOLVED: To accurately generate a heart rate synchronizing signal and a warning signal based on the electrocardiographic waveform on which a pacemaker waveform is superposed.

SOLUTION: A waveform detecting part 61 of a heart rate synchronizing signal generating part 6 provided in an ultrasonic diagnostic equipment detects QRS wave and a pacemaker waveform separately from the electrocardiographic waveform of a subject on which the pacemaker waveform is superposed. A synchronizing signal generating part 62 generates a heart rate synchronizing signal for determining the time phase of heart rate synchronizing image data based on the detected QRS wave. On the other hand, a warning signal generating part 63 generates a warning signal for stopping the operation of a medical device having the possibility of giving interference noise to the heart pacemaker based on the pacemaker waveform detected by the waveform detecting part 61.
