I, actually, think that is one of the sensations I felt with my holter on last week...they said NSR....what the????
I have psvt and had an ablation Feb 2014, all is well, but from time to time I do have pac and also feel the 2 or 3 sometimes 5 plus...then everything returns to normal but my mind... sometimes I think we over think....panic and that just starts the cycle all over again....
I get these too. Very Freaky. Sometimes up to 9 in a row before returning to normal. I think they are either runs, salvos or non-sustained ventricular tachycardia, but maybe someone else here can explain it better than I can.
Anyways, 7 years with them and i'm still here.
