  • ICD settings

    Hi,

    When is your ICD set to deliver a shock?
    I just got mine in March and it is set at 240 BPM. I am 40 and asymptomatic.

    Just curious!

    Hi,

    My ICD was set to deliver a shock at 183bpm, but after I received two inappropriate shocks playing tennis, it was changed to 200. I'm 27 and pretty active and so far I haven't tolerated meds very well, so it's a struggle to keep my heartrate down.

      Jeez - Mine is set at 150. Never had a shock, though I've exceeded 160-170. I was told it can distinguish a normal fast heart beat and an inappropriate one racing. I just learned that kids are set faster than adults.

        Librarian Girl,

        What were the shocks like that you received while playing tennis? Were you incapacitated immediately, did you faint?
        I continue to bike since my implant but I am wondering if I am going to crash and burn if I get shocked while biking.

        Thanks

          Mine is set to shock at 220. I workout regularly and pretty much have no symptoms.

            Lumax,

            You know, actually receiving the shocks relieved a lot of my anxiety of having the ICD. It was far less painful than I thought it would be and I knew my ICD worked!

            I had been hitting the ball for about 5 minutes.... not running or doing anything really strenuous. I thought, hmm, my pulse feels pretty fast, better take a break. As I'm walking off the court I feel what I think is the man I am playing with hitting a tennis ball very hard at my chest. I thought he hadn't realized that I was done and had continued to hit the ball. Then I looked down and realized there was no ball. So, my ICD shock felt like a pretty good hit with a tennis ball to the chest.

            The worst part was realizing, oh shoot, I must have reached the bpm to trigger a shock, and if it keeps up for 10 more seconds it's going to happen again. Then of course, it happened again.

            I didn't fall down, but I think that may be because I had come up with an alternate explanation for what I felt. I did double over after the first shock and made it over to the fence for the second shock where I just kinda held on until I could make my way over to a bench. Never lost consciousness... which I think is pretty normal for an inappropriate shock.

              Re: ICD settings

              Marc... that is pretty low for the top setting. Are you sure that is for defib and not pacing? Usually the pacer will attempt to pace a fast heart rate down at a specified high setting like it will do for a specified low setting it will pace up. Then defibrillate at a higher setting, if the pacing down does not work... Just curious.

                I'll give the electrician a call - I remember a couple of different folks telling me that, but then again, I'm prone to "Emily Letilla" syndrome. . .

                  Marc,
                  When you speak with the electrician, you might be sure you get all of your settings. I have 3 settings on mine. My first setting is monitoring mode which is set at 150. You never got shocked at 160 because you weren't in V tach. You probably were not paced either because you didn't reach your antitachycardial pacing setting, which would be greater than 170. These gadgets can tell the difference from a ventricular tachycardia from an atrial tachycardia, therefore no shock necessary.

                    Hey Marc;

                    I've been given three numbers for the ICD: Pace at 40 on the low end. Pace at 185 on the high end. Shock at 219. I was also told that, in general, the device can detect the difference between an increase in heart rate because of activity and that there is a problem.

                      I really screwed it up!
                      Pacing: Atrial is @ 150, Ventrical is @ 185, and Shock is at 225
