Heart Rate after exercise

Hi, I am a healthy 36 year old female who exercises 3-4 times a week (weight training and cardio)  I had an EP study and AVNRT ablation 2 1/2 years ago, during this I also went into Atrial flutter and atrial fibrillation in which I was cardioverter 3 times, but not ablated for AF & AFL (apparently I was to tricky?) .I have not been into AF & AFL after this time but have had experienced and been diagnosed with inappropriate sinus tachycardia on several occasions up to 170 bpm. (all in sinus rhythm)
I am now experiencing after exercise my heart rate will drop  from 180 bpm to 135 bpm in the normal manner, then about 5 minutes later it start jumping around rapidly from 135 to 86 to 125 back to 95 - 125 - 100 - 135 it will continue this for approximately 1 hour. If I lay down it settles slightly. Do you think this is just part of my inappropriate sinus tachycardia? I have had a stress test in which came back normal as they didn't monitor my heart rate after exercise as much as I begged.  
I have given my heart rate monitor to someone else to use, to make sure it wasn't a glitch, this did not happen to them. This is not a problem in my heart rate monitor.
Your advice on this matter would be greatly appreciated.

Hi. I guess I have never heard of anyone using a heart rate monitor. Most people here are accustomed to using an event recorder or halter. These devices measure voltage fluctuations at various points on the surface of you body, and from these measurements doctors determine in what order the different parts of your heart contract, as well as the paths of "enervation". They can also tell your heart rate, but this is just a side effect.

In inappropriate sinus rhythm, your  heart beats normally, so an event monitor essentially doesn't provide much. Yes, they can see a fast heart rate, but you already told them that, and as I said the main purpose of an event monitor is to understand the origin and paths of conduction. If you have inappropriate sinus tachycardia, you origin and paths of conduction are normal.

System issues can affect heart rate.  For example, emotions, hormones, blood sugar, dehydration, and exercise and overall conditioning can all affect heart rate.  So, one has to differentiate between a system issue and a cardiac issue. True, you could have something wrong with your natural pacemaker, but they have a long way to go before they get to that point.

I sometimes have this sort of trouble myself. When my heart beats fast and in sinus rhythm, I have a hard time sorting out whether I am being emotional or having some other problem, but in my case it is usually explained by: lack of sleep, too much caffeine, low blood sugar, or excessive worry. I cope by taking care of these things first. Usually, my problem diminishes after I do that. You can always see your internist for some ideas too.

All good :) Thanks for your advise. Yes I should push a little harder. I don't want to have a stroke if I was going into AF all the time. Thanks again :)

I should probably add something here at the risk of being too wordy (sorry).

An event monitor would be useful for your cool downs, just to verify that you are in sinus rhythm.  You said you were in sinus, but I dont see how you can say that without a trace, especially if you have atrial flutter or atrial fibrillation, and are experiencing high heart rates. If it were me, I would spend less time begging, and just go get that event monitor again. (be persistent and remember that the squeeky wheel gets the grease; dont worry they'll fork it over)

Thanks for your reply. Yes I have used halter monitors in the past, very often. this is where my electrophysiologist diagnosed me with my initial SVT and then later inappropriate sinus tachycardia (tachycardia, in sinus rhythm)  he then suggested I use a heart rate monitor during exercise, this is just a basic 2 lead device that captures heart rate.
Hormones, bloods etc have all been checked, Sleep is great, 1 cup of coffee a day & I have been exercising for the last 10 years, so in good shape, and eat a great diet.
I really haven't found anything on the internet with the same symptoms. Was hoping someone might have had the same issue and might be able to help.
