Any Runners or Cyclists Out There Who've had an ICD Implanted for V-Tach?
I'm a brand new member of the Pacemaker Club. I'm a 60 yo male, a lifetime runner and cyclist, and had my first pacemaker implanted, a Medtronic Cobalt XT DR MRI Surescan with dual leads, this June. My basic heart history is that a few years ago it was discovered that I have scar tissue from myocarditis of the LV. Soon after that I developed afib which progressively got worse and I had to have an abation to stop it. The ablation succeeded. After implanting the ICD, my EP told me that the scar tissue from the myocarditis and ablation caused the V-Tach (though I think there's more to it than that). I'm on Eliquis, Plavix, Lisinopril, and Metroprolol. My pacing modes are AAIR and DDDR. Rate response is switched on. Upper tracking rate is 140 and lower is 50. I'm paced in the RV less than 0.1% and in the RA 56%. Monitoring over the past few weeks has not revealed any arrhythmias.
The trouble is, I'm having a hard time finding out much information about my future as an endurance athlete who has had V-Tach and now has an ICD.
Before the V-Tach incident which led to the pacemaker implant, I went running and was a mile into my warmup when I felt faint and had to stop for a few minutes. I'd never had that happen in all my years of running. After a few minutes of rest, I was then able to carry on with the rest of the three-mile run without incident. Then a couple weeks later, I did a hard interval workout on my bike: 10 X 400 meters with about 100 meters of rest between. Felt fine during the workout. But during my cool down ride home, I felt faint. So I got off my bike, sat down, and took my pulse. No pulse. I considered calling for help, but figured that this was similar to what I'd gone through two weeks earlier. Sure enough, the sensation of fainting went away (I didn't pass out) so I rode (easily) the rest of the way home. At home, though, I was breathing hard, like I was still in a workout. Using a handheld cardiac monitor, which displays EKG, hr, and provides a diagnosis, I discovered that I was in V-Tach. My hr was 235; I waited a bit, took another reading and it didn't change, so I called the paramedics.
The paramedics and ER staff failed to slow my heart rate down using Adenosine and Amoidarone, but finally succeeded using Procainamide.
I was transferred to an ICU; met with EP the next day who said he would give me an ICD implant.
