42 yr old female - 4 kids - irregular heartbeat (PVS's diagnosed at age 17 - by several EKG's, echocardiogram and continual EKG monitoring while inpatient for 2 days) - have had 3 holters since 17 - each showing PVS's bigeminal fashion. Echo at that time was completely normal. Most recent 24 hour holter (6 weeks ago) shows: Ventricular Ectopy - 4 Total, Supraventricular Ectopy - 2,436 total, Sustained SVT greater than 150 - 2 total, Sudden increases - 44 total and sudden decreases - 14 total. Min Heart rate of 50, max of 164 with an average of 85. States: (1) Rhythm is Sinus with 1,206 pauses less than 2.5 seconds and sustained S. Tachycardia (Max HR 164 bpm -occured at 8:14 a.m.) (2) Rare VPB's were observed, (3) Frequent SVPB's were noted. My GP sent me to cardiologist - he didn't seem concerned....I go for a echocardiogram in 3 weeks. He is going to request the strips to review from the holter as he only has the report to review. He said my physical exam today (listened to my heart, my neck, etc and did short baseline EKG) was normal and if nothing "funky" shows on the strips or the echo that I am normal and fine. I'm concerned - aren't the Supraventricular Ectopy of 2,436 high? Aren't the pauses of 1,206 high?! I'm really freaking out about the pauses in particular. I don't experience any dizziness, shortness of breath or other symptoms that I am aware of when these occur. He didn't do a chest x-ray today bc I just found out I am pregnant and found out (unexpectedly) last week. I'm really worried - wondering if these are at all possibly normal? I do tend to be a little anxious from these skips and pauses. My BP is normal. My cholesterol is normal. My thyroid was within normal range. I guess I'm just plain scared! Thanks, in advance!
