I was hooked up to the machine, for 20 minutes my heart rate was 95 to 112 range while i waited sitting down. The stress test started and i was quickly at 150, then 170 within 2 minutes i was in the 190 to 210 range, the technician told me to stop, after 5 minutes my heart rate was still at 160 to 140. 15 minutes later still at 120.. Eventually he said it's ok lets un hook you. My doctor looks at the results and said "everything looks fine".. I said what about the fact that i hit 209 with just a minute or 2 of brisk walking not even running?.. He said " your heart is supposed to go fast, don't worry " ... Should i be worrying? Or is he right?

hello and welcome,

i have never heard of such a 'flip' remark from a doctor. And I have had some doctors that were not so great with bedside manner. It could be that you were just having an anxiety issue or worry that ran your heart up when you were on the treadmill.
If I were you, And if you are worried or concerned about your heart, i would seek some second opinion, and have the doctor spend some time with you, going over the answers to your concerns.
Good Luck!!

Thank you,
yes from what I've heard from others this dr is pretty bad at his job, i had some other tests done which showed my heart is fine structurally except for the abnormal EKG ( according to him).. Ill seek a second opinion soon a 24 year old shouldn't be having a heart rate that high with just some walking

I'm curious why you had the stress test? I'm not a doctor, but I have read that the Maximum Heart Rate is generally considered to be 220-age.

/en.m.wikipedia.org/wiki/Heart_rate

The above Wiki page covers several formulas used for the Maximum Heart Rate. This is also, I believe, the maximum rate to be obtained during prudent stress testing and not necessarily the maximum the heart can achieve.

In any case, heart rate is also influenced by conditioning, medications, and a number of other factors, there are no absolutes. After 5 minutes to be at 210 briefly, depending on those other factors, does not sound unreasonable.

At 55, I had a stress test, reaching 75% of the expected rate. If they calculated it as 220-age, 165 would have been my target. 75% of that is 124. My most recent stress was done under my normal medication with a Beta Blocker, and after 5 minutes on the treadmill, my heart was only at 91. I stopped it at 5 minutes, my legs were giving out, and though I could have made another minute, didn't want to take the chance.

What is the nature of the abnormal EKG? Also, how long did you stay on the stress test? Are you male or female? Overweight by more than 20 pounds? Tall, short, average? Conditioned or sedentary? Smoke? Drug use, including prescription, supplements, caffeine? If you use illicit drugs, be sure to let your doctor know.

I'm 25 yrs old, 145 pounds, male, 5" 3. EKG says sinus tachycardia. My target was 175, i passed that in no time. The reason for the stress test was to see why i have the sinus tachychardia, now I'm being sent to an electrophysiologist. Because I'm in better shape than move of my friends, yet i can't walk for more than ten minutes without being out of breathe and my heart getting like it's going to burst, and they are fine like 10 minutes of waking is no big deal

when we go hiking i have to stop every half mile to catch my breathe, and relax, they make it all the way to the top of the trail and back and im still halfway with my heart bursting out my chest, going 150 - 170 bpm, and theirs is fine like they went for a brisk walk. But we're all the same age. And don't of these guys are fatter than i am. I don't smoke or drink, and have been like this since i was 20, before that i either didn't notice it, or didn't have any issues cuz i was very acting, went to the gym, played ball regularly . then this heart pounding, chest hurting shortness of breathe came along and put a stop to all that.

Has your doctor mentioned Inappropriate Sinus Tachycardia? Sinus Tachycardia means a normally structured heart rhythm 100 beats per minute or more. If someone exercises, their heart goes into Sinus Tachycardia during the exercise, appropriate Sinus Tachycardia if you will.

www.heartracing.com/physicians/inappropriate.sinus.tachycardia.asp

/en.m.wikipedia.org/wiki/Inappropriate_sinus_tachycardia

Inappropriate Sinus Tachycardia is a normally structured heart rhythm 100 beats per minute or more at times not associated in the average person with having a markedly increased rate.

The first link does a nice job discussing possible causes, treatment options, and prognosis (which is excellent as it does not shorten your life span).

Beta Blockers seem to be a starting point for medication, as well as Calcium Channel Blockers.

If you have specific questions, write them down as you think of them and take the notes with you to the office. If he/she suggests an ablation, consider getting a second opinion.

My heart rate is normally above 90. I wake up with a HR of 105 110, it's almost never below 90, my cardiologist said the stress test was fine, but he's covered with my EKG results, so I'm seeing an electrophysicist

You may have Inappropriate Sinus Tachycardia, the Electrophysiologist will be able to determine. On waking, believe it or not, the sympathetic nervous system starts speeding things up. Make sure to keep us updated.
