Why would I need another surgery regarding my pacemaker? 

I had a pacemaker implanted on October 28, 2011. An ECG noted that the threshold was 6.5 volts at 0.4 milliseconds which was significant from before. I was told that I need a new lead. One would be taken out and not put back and another one replaced. (now is 5.50 V 1.10 ms, initial 7.50 0.4.) I do not understand why only after 5 months I need a surgery.

Either the lead has dislodged or fibrosis and scar have formed at the tip of the lead. At the current setting, the longevity of the device will be drastically shorter than expected.
