Recently I had a check up (last was three years ago) of my heart as I am anxious, have panic attacks, and it is kinda helps me to relax to know that my heart is healthy. Echo came ok, stress test showed 1 couplet PAC during the recovery period, on the Holter they found 18 PACs and 3 pauses at 6AM when I was sleeping with the longest 2400ms. Of course I felt nothing, as I was sleeping. This is the first time I got it detected as I have done the checks once in a three year periods. Should I be worried? Are those pauses dangerous?
