Abstract

A pacing-pulse detecting circuit 3 detects pacing pulses from an electrocardiogram signal led from an electrocardiogram electrode 1. A mode-status judging means 21 judges a mode status, a pacing mode or a nonpacing mode, on the basis of the pacing pulse detected. The detect result is transmitted to a CPU 5. The CPU 5 causes a display device 10 to display the result. An operator sees the display and operates a key 22, and gives an instruction to start a blood pressure measurement to the CPU 5. The CPU 5 drives a pump 13 and an exhaust valve 14 to supply and discharge air to and from a cuff 11, and measures a blood pressure by use of pressure data led from a pressure sensor 15.

Claims

1. A patient monitoring apparatus for monitoring at least electrocardiograms led from an electrocardiogram electrode and blood pressure information output from a non-invasive blood-pressure measuring apparatus, apparatus comprising:

pacing imcompetence judging means for judging whether or not the pacing by a pacemaker is imcompetence, on the basis of said electrocardiogram; and

third blood-pressure initiate means for immediately initiating the non-invasive blood-pressure measuring apparatus when said pacing imcompetence judging means judges that the pacing is incompetence.
