I am 34yr old F, 135lb multi sport athlete with near syncope episodes. 24 hr holter showed 3 single pvc's, 8 atrial couples, 12 single PAC's. longest rr interval was 1.4, and longest nn interval was 1.4 also. average hr was 70, with min at 47, and max at 122 (no exercise happened during holter). what are the norms for pvc's and pac's ?? is this normal?
