I'd like to consult the group wisdom on what I assume are missed beats. The symptoms happen at night. I feel ‘beat, beat, pause, beat, beat, pause’ and this can go on a bit. I sometimes feel underlying atrial arrhythmia. Both are intermittent and don't happen every night. I wake up feeling groggy and a bit nauseous when they happen. Can anyone shed any light on these ‘missed heart beats’ and whether they could be settings related or progression of what has been described as first degree AVB or something else?
Settings wise, I have an AVD of 200 ms programmed and a further programmed AVD extension of 150 ms. The extended AVD is applied when my PR interval exceeds 200 ms and can repeat up to x 3. This AVD extension must be used a great deal as my PR interval is longer than 200 ms.
Note: I have questioned these AVDs several times now, and have encountered very frustrating, unexplained reluctance to change them.
My a.sensing level was also raised (not my choice) some months ago. This has helped with symptoms caused by over sensing which plagued me for months. However, it has seemingly removed ECG evidence for AT and first degree block. It seems too high.
I became aware of the pauses after the sensing level was raised a few months ago.
*Edited for sense.
