PURPOSE: To screen a patient by obtaining a reference wave form from an electrocardiograph obtained by connecting a pacing lead with detecting and pacing electrodes in a pace maker embedded into a body, storing the reference wave form in an external programmer to compare new one with the reference wave form. CONSTITUTION: A lead 14 a pacing electrode 16 and a detecting electrode 18 at the tip end is inserted from the large vein 20 to the right ventricle 24 via the right atrium 22 of a heart, and a pace maker 12 embedded in a body is connected to the other end of the lead 14. After the pacing electrode 16 and the lead 16 come into a stable condition, data interpreting a cardiograph is detected and stored in the pace maker 12 as the reference value and also transmitted to and stored in a programmer unit 10 as the reference value. Every time a new cardiograph is obtained, whether myocardial ischemia exists or not and the transition are judged noticing on changes of the cardiograph, especially on changes of the ST part. Thereby screening suitable for a patient is carried out. |
