What are the odds?

I had a halter monitor test done by my PCP and they said they recorded several pauses. One that was 9.5 seconds, one  6 seconds and two 3 seconds. I was referred to a cardiologist who recommended a pacemaker. What are the odds that in that 24 hour halter test there are 4 pauses but now my pacemaker has not recorded any in an 8 month period?

I also did not have tachycardia until after the pacemaker implantation. Can the pacemaker have triggered this since it is a "foreign" object in the heart?

I am just surprised a little by what's happen to you.  I am assuming that you are an otherwise healthy person and don't have any congenital heart problems or had any surgeries in the past.  It's very unusual for some of you age carry the diagnosis of SSS and to require a PPM.   I am wondering whether you had some profound vasovagal bradycardia instead.  Anyways.  There may not be any bradycardic episodes now because the pacer is pacing you out of them.  However, if there isn't any pacing going on at all then the diagnosis was probably incorrect and you probably didn't need the pacer.  Pacemakers can sometime cause rapid heart rates due to something referred to pacer mediated tachcyardia.  This is not a malfunction but a programming glitch which can be easily overcome.  Otherwise, if this is all your own sinus tachycardia then it's not pacer related.

It came as a surprise to me as well. Yes, I am a healthy active adult with no major health issues. My pacemaker does not pace, it triggers only if I go below 50 beats. Also, a few days after implantation I ended back in the hospital. he ventricular lead had unhooked and poked the membrane wall. They had to do a pericardial window to remove fluid from my heart. I am all healed from all of that but again have the tachycardia. My 1st cardiologist said I would just have to stay on beta blockers from now on. I figured there had to be a better way...I can't work out as much. I have to recover for a day or so after workouts but have gained 15 lbs since Dec.(original surgery). I saw a 2nd opinion and they now recommend a ablation procedure. I have read some on this procedure but am still not sure that it is the solution to all of this.
