International ClassA61B 005/02Foreign Application Priority Data1985-09-23 DEAbstractA blood pressure measuring appliance having a pulse beat detector responding to arterial pulse beats, an ECG signal detector and a time measuring apparatus which ascertains the time intervals between peaks of a predetermined type of the ECG signal detected by the ECG signal detector, preferably its R-peaks, and pulse beats in each case following the R-peaks and detected by the pulse beat detector. A display apparatus displays a datum representing the duration of the ascertained time intervals as blood pressure information. The blood pressure measuring appliance must merely be calibrated initially, for example, with the aid of a sphygmomanometer, in blood pressure values. The inflatable bag can be eliminated for further blood pressure measurements. | |
