Follow-up
All patients had minimum of one month follow up. The mean follow-up
duration was 4.7 ± 1.9 months (range 1-7 months). The pacing threshold
remained stable at 0.525 ± 0.07V at 0.5ms pulse width and sensed R wave
amplitude 15.6 ± 7.3mV during follow up (table 2). The unipolar pacing
impedance decreased to 663.1 ± 57.9ohms (p value 0.002).
Echocardiography showed significant improvement in LV ejection fraction
from 47.6 ± 11.2% to 55.9 ± 5.4% (p value 0.017). The length of
the lead inside the septum was 10.3 ± 0.82mm. There was no acute or late
lead dislodgement. There were no episodes of thrombo-embolism, pocket
infection or mortality.
