My heart rate was about 300 this morning at the gym 4 the 1st time, why is that?

I%26#039;m not sick or anything , and i didn%26#039;t feel any weird it all. I was in a cardio machine. Is that bad, i hope it%26#039;s not.

300??????

Seriously doubtful. That is extreme tachycardia.

Yes that is bad, lol.

300 is enough for your heart to blow up. i believe the machine may have been wrong.

220 minus your age is considered a safe working heart rate.

300? unless the morgue has wifi, something is wrong in your calculations

Did the machine tell you it was 300 or did you count it? If it was that high you would feel palpitations and not feel normal. And to those who said 300 would make your heart explode or whatever, I have to disagree. I have supraventricular tachycardia and it%26#039;s been recorded on an EKG at jumping from 80 to over 250 in a matter of seconds.

the machine was broken. if you feel fine, there%26#039;s no way your heart rate was 300.

I suffered from attacks of SupraVentricular Tachycardia. My %26quot;resting%26quot; heartrate would go from 70 up to 240 beats per minute from one beat to the next. Paramedics worked on me a few times and I had quite a few trips to the ER. I never came close to 300 though. If it rose gradually during exercise, and slowed gradually, it%26#039;s not the kind of electrical problem I have, but you are probably pushing it past a safe limit.

This is a question for a doctor. You should contact one as soon as possible.

That is deadly. Maybe the machine is off. Did you check your heart rate yourself? If this number is true you should get a checkup with your doc. You may have hyperactive thyroid or a heart condition. Make sure you are not taking anything that could have caused this like diet pills or heavy duty energy drinks.
