My P.R interval is around 202-205 I need to get it under 200 by next week when I go screen for a study in Tennessee,I really don't know if this study require it to be under 210 or 200 I just want to be under 200,any feedback?

I have that issue, too. What works for me is accelerating my heart rate, which seems to be inversely proportional to PR interval.
Two possibilities: (1) hold your breath during the EKG, if possible starting from when they're attaching the electrodes, but making sure to keep your chest moving so they think you're breathing normally; (2) overload on CNS stimulants, even if it's just a few caffeine pills. The issue with (2) is that it can sometimes also mess up with other EKG measurements.

I know that when i stopped using caffeine my ekg got a lot less jerky; fewer pvc's. this used to keep me out of doing studies at parexel, so i had stopped screening there years ago, but i happened to be in baltimore recently and decided to screen at parexel and got in, i'm headed home right now from part one. review later. i dont know anything about p. r. intervals. is there an ekg's for dummies or soing like that? i now know little more than when i started doing studies n years ago.

Try to hold your breath for as long as you can before they run the EKG. Where I usually do screenings, they hook up the leads then wander off for five minutes before running the machine, but in other places they go straight from hooking up the leads to generating a reading. Aim for at least 30 seconds of breath-holding before the machine starts to do the reading, longer if possible. You MAY notice a difference. When I do this, my PR interval shortens by around 10%, which almost always gets me over the line.
Don't bother with those cheap mail- EKG machines you see advertised on Amazon for a hundred bucks. They're nowhere near sensitive enough for this sort of thing. If you want to measure your PR interval at home, you'll need a big, expensive multi-lead machine -- and if you can afford that, you probably don't need to do studies.

Vark, one's PR interval is largely a matter of chance: most healthy people have a PR interval under 200 milliseconds, while other healthy people (like me) go up to around 215 milliseconds. The standard clinical limit is 220 milliseconds, but for certain studies, particularly those involving cardiac drugs, the stricter 200-millisecond limit is applied. A mildly lengthened PR interval such as mine is known as a 'first-degree heart block', a terribly scary name for soing entirely benign. (The more accurate term is 'first-degree atroventricular block'.) Beyond 220, however, and mortality rates start to creep up. A third-degree heart block might involve having a pacemaker fitted.

I suspect a Medical Examiner is reading this post and getting an orgasm simultaneously! If thats not enough their is some inexperience Resident at Harbor Hospital waiting to take her 1st go at cracking a chest .
Next is going to be a conversation about manipulating EEG brain waves to get a retard into a study. From the sounds of it they already quite a few enlisted. If your azs can engage in conversations like this contrary to EEG readings suggesting your computer is malfunctioning the other half of your brain is still working. Just may be you can go back to school, Get a job and see if you can trick the boss into giving some overtime. Then you might be able to catch the guy on the block sneaking into your apartment because he didn't know you were coming home from work early. And stop telling people that your kid doesn't look like you because you were taking an investigational medication when he was conceived. He doesnt look like you because it wasnt your catether that was in use when the magic moment happened.

Just out of interest, what sorts of meds have you been messing with in your recent clinical studies? Any noticeable long-term effects?
