Old Pacemaker at the End of Life

question 48

Short Answer

Old pacemaker at the end of life. Replacement of pulse generator.
After local anesthetic had been infiltrated, an incision was made over the right upper chest where the pacemaker had been implanted. The old pulse generator was removed. The new pulse generator, a Guidant Discovery DR model #1275, serial #abcdefg was implanted.
The atrium sensing was 2 mV, threshold 1.4 V, impedance 500 MHz. In the ventricle our sensing was 7 mV, threshold 1.4 V, and impedance 5600 MHz. There was no VA conduction.
The new pulse generator was attached to the old leads. Left and DDD are lower rate 75, upper rate 120 beats per minute. "AV delay" 150 ms and mode switching is on. The wound was closed in layers.
