    [pacing thresh holds]

    I got my ICD read today and i was just wondering, what is the purpose of the pacing thresh hold? I hate it!!! It makes me very dizzy and then im totally worn out for the day. Just looking for some insight to this.

    Dear Bryan,

    From Medtronic's web site:

    "The pacing threshold is the minimum amount of energy (or battery power) needed to make the heart beat consistently. Determining the pacing threshold is important to ensure consistent pacing and to maximize the pacemaker's battery life.

    Checking the sensing threshold ensures that the pacemaker can detect (see) the natural electrical activity of the heart. Determining the sensing threshold is important to make sure that the pacemaker only paces the heart when needed."

    Hope this helps,

    If your thresholds are not set well you may run through battery faster...however if you are not feeling well talk to the doc about resetting it ... ifyou need a battery sooner..so what as long as you feel better!

    I just had my ICD read on Friday. First time since implant in August. My heart rate normally runs about 55-65 bpm for me, so the surgeon set my pacing threshold to 40 bpm. So in the event that if/when it gets that low, it should attempt to pace my heart faster.

    Good news... no pacing events logged. Bad news... one V-Tach event logged, but it stopped just before I needed a jolt (good news).


    It sound like the info you stated is specifically for pacemakers which work 24/7. ICDs should only pace when the threshold is reached.
