Question Title: atrial vs ventricular pacing II

Thanks so much for your earlier replies regarding the above mentioned subject.

However: I have one more question about the issue atrial vs ventricular pacing and PMT interventions.

As I mentioned in my previous e-mails the check up report showed several PMT intervals. The suggestion was to pace atrial only, which did not seem very appropriate since I also take lanoxin as well as sotalol and was paced 65% ventricular. They agreed with your opinion here as well.

Now the question remains: since the AV-interval is set at 230ms with rate adaptive AV interval feature switched on if it would be wise to decrease the AV interval just like you said. I also looked into the AV conduction histogram report (only 4 days reported) and the data are as follows:

* AS-VS 0,2%
AS-VP 37.9%
* AP-VS 10.7%
AP-VP 51.1%

The question is:

1.
what is the meaning fo these data?

2.
would these data suggest that an decrease in AV-interval would be OK?

3.
could the PMT interventions be caused by the long AV interval? Someone also suggested an atrial arrythmia as cause for the PMT

Thanks so much for your reply!
