sinus tachycardia with short PR interval

I had an EKG done at work. I actually work on a cardiac stepdown floor at a hospital. I have noticed that for the last few months my HR stays between 115-140. Thats resting. I do not drink caffiene. And no, I dont take diet pills or any kind of stimulant. I am only 22 years old. Anyway, since my rate has been so high i did an EKG during my downtime today. I know you really need to see it to know anything, but this is what it said. HR-116(down from the norm) borderline EKG, sinus tachy and short PR interval. the interval is 104ms. I believe they consider anything below 120ms short. I dont understand why my rate would stay up like that. Im sure it has something to do with stress, but I have no more than I ever have. Heart problems runs in my mother started taking cardiac meds in her early 20s..beta blockers i am guessing. It just worries me because I have such a history or heart disease in my family. Yes, I know I need to go see an MD, but at the moment I am so low on funds, and my new insurance doesnt really pay anything, I have to put off going to a dr for now. I know really i need to have labs drawn and some other tests to diagnose the problems, but i just wanted to hear some opinions until i can go. I need to exercise, i used to but i havent in a year or two. im not overweight..around 143..actually about 15 pounds heavier than i was prior to nursing school. go figure. i have been having sereve insomnia the last few months as well. could my heart rate have anything to do with that? besides stress, i just dont see why my rate would stay so high at my age. any ideas?

Re: sinus tachycardia with short PR interval


This is going to be a frustratingly uninspiring response, I think. I've been dealing with sinus tach for about three years now and have tried a couple of different beta blockers with mixed success.

I have been to three different specialists, and they pretty much all agree on one thing: sometimes these things just happen, and no one knows why. My current doctor told me that sinus tach usually spontaneously onsets for women in their 20s-30s, so you're perfectly in the target demographic. I gleaned that about 50% of cases also spontaneously resolve on a time scale of 5-10 years, but the doc was hesitant to cite that as a definite statistic.

Usually mine is just exercise-induced, but over the past two months it has become pretty constant. I know you already know that you should get all the tests done just in case, to make sure it's not something more serious, but there's a chance that this might just have to be one of those things you learn to live with. Sorry.
