Abstract
This paper gives the results of stimulation threshold and R-wave sensitivity messurements in 31 patients who received two time PM replacements during the period of October 1975 to August 1978 in our hospital.
The study was made on 31 patients to measured stimulation threshold (bipolar, unipolar), R-wave and impedance.
Usually we have used uJ stimulation threshold by Ohms low.
1.) The 30 patients of bipolar pacing, stimulation thresholds were stabilzed in 12 patients (40%), increased in 12 patients(40%) and decreased 6 patients (20%).
2.) The 16 patients of bipolar and unipolar pacing, R-wave sensitivity were stabilized in 10 patients (62%).
Though the most number of patients has no relation in stimulation threshold and impedance.
