Fast Heart Rate and a Heart murmur?

I went to the doctor finally. I've been living with this my entire life but I've had enough. I'm 18 now. Everytime I work out... exert pretty much ANY energy my heart rate beings to soar. To a point its uncomfortable. For example at the gym It'll go as high as almost 200 if i'm really working hard... a lighter workout it will be about a 190 its terrible. I'm in diving, and thats not strenuous at all... yet my heart races during that. My resting heart rate is normal however.

I was diagnosed previously with a heart murmur, but recently my doctor said it was very loud. Which could be dangerous I suppose.

My doctor said it could be that iwas born with a faulty valve or not enough chambers or something?

I also have a history of bad heart valves in my family.

I have a stress echo test on monday and I was jus wondering if anyone has gone through this

or had similar symptoms and could tell me what happend to you. or whoevery ou know with it.

Angie is mostly right but she misinterpreted the question.

A stress test and an echo are different things

A stress test is on a treadmill and they try to get you up to you max heart rate to see what an electrocariogram looks like under strees as opposed to at rest...this is mostly sdone to examine for a different heart problem like hardening of the arteries where blood flow to the heart may be compromised by blockages. you may get this for investigation, but the echo is what is important to you.

Echo is short for Echo-cardiogram, it is an ultrasound procedure, You will lie on a bed, you will have someone smear a jelly on your chest and move what looks like a microphone through the goo.
On a monitor it will show the heart beating, the blood moving in the heart , the valves opening and closing. They will measure size of heart, thickness of heart, EJECTION FACTOR, and look at valve motion.

Ejection factor is ....You have a chamber that takes in blood and during the next beat , it expels some of this blood. It can't expel all and 55% or more is normal, 50% or less is not good.
The reason not all blood is expelled in a good heart is there will always be some blood left in because the heart wasn't built to send it all out.

But the valves , if they don't close properly, allow blood to backwash. so the heart can't get the normal amount out.
Blood enters a chamber through a valve, which is like a triangular flap, flap should close and next heartbeat contracts the chamber and sends it out through next valve.
If first valve doesn't seal, it lets blood go backward.

When you excercise, you don't get efficient bloodflow so your heart speeds up to get oxygen to your body when pumping is inefficient. you can over tax your heart and get into fibrillation....YOU DON"T WANT THAT.

So take the tests, and if necessary have and bad valve replaced...the tests are not hard but don't fool with your heart.

Good luck

A stress test, they hook you up to electrodes (patches on your chest that have wires running to a monitor) and start you out at a very slow walking pace on a treadmill. Then they start moving the pace up till your heart rate gets to a certain point. Then, if nothing happens, after a time, they'll bring you back down.
If you fail the stress test....they'll probably do what's called a heart cath. They put a small tube in the femoral artery of one of your legs (in the crease between the torso and leg) and thread it up to the heart. They then send a dye through the tube while x-raying to get a better picture of the heart and how it's working. Depending on how that looks they may try to fix something then, or they may have to do open heart surgery to fix your problem.

hi there... its nothing to worry.. i was recently diagnosed with a hole-in-the heart.. they frightened me saying that i shouldnt do strenueus exercises and all... but i ran my cross country, joined and played hockey, have been running for some time, and am still alive! but that does not mean that u dont take care of yr heart... the moment u feel umcomfortable, either stop wad u are doing or reduce the strain that u are putting on yrself for tt moment.. take a deep breath.. continue ONLY if the uncomfortable feeling has gone... if there's anything else, feel free to ask me! Take care! =)
