New settings following exercise stress test
Well today I had my exercise stress test and download.
I was hoping my block was not present during exercise but unfortunately it was. The AAI-DDD mode was not really working and probably explained some of my symptoms. In fact even though AAI-DDD was suppose to minimise pacing (it actually only intervenes if 2 or more Ventricular beats are missed in 4 atrial beats) I was still at 80% pacing.
I must have been constantly switching between AAI and DDD. I suspect that was not ideal.
My upper track rate before the test was 150bpm, and I surpised to see that they could not get my heart rate to go above 150bpm due to the AAI mode and wenkebach rates. My upper track has now been moved to 180bpm. They said that was the maximum they could do.
They then did a lot of analysis and adjustments and right in front of my eyes my heart rate jumped to over 170bpm. It did feel easier at that stage. They had to jump a few steps on the Bruce Protocol to get my heart rate higher.
I am now in DDD mode with rate adaptive AV delay so I suspect I will now be paced 100% of the time. This aspect is disappointing but then they did try to minimise the pacing as best they could and it was clearly not working.
I have another month of personal testing to see if exercise and daily activities are better and they will look again.
All the best
