Intense Heart Beat!

[niKk13]

Hey, I'm 15 years old (turning 16 in a couple of weeks). For about half a year now I've noticed that my heart beats very fast and more intense than I feel comfortable for it to be, and when I get up fast I get dizzy sometimes with blurred vision. About a year ago I was at the hospital for an Asthma attack. My stats seemed fine then (BP, BPM, ETC...). Sometimes, even after sitting down for an hours (in class) I can notice my heart beat beating very loud, and even sometimes see it make a little bump in my chest as it beats. Now I am very slender, but this seems very unusual. After intense activities, my heart beat becomes distracting and I can feel it in the back of my head. It's very scary at times. I have no other symptoms. Should i seek medical attention?

Hi
Welcome to the forum!
Yes, you must consult a doctor. What you have are palpitations where you become aware of your heart beating very fast. Palpitations may be normally felt if you are overexerted. If you have cough (ASTHMA) and are taking medicines that contain asthalin or terbutaline then the palpitations can be a side effect of the drugs. Chemicals like adrenaline, alcohol, caffeine, cocaine, amphetamines, and other drugs all cause palpitations. Disease (such as hyperthyroidism and pheochromocytoma) or mitral stenosis, panic disorder can be the cause. Palpitations may be associated with heart problems, anemias and low blood pressure.
In your case anemia and use of bronchodilators and puffs for asthma are the most likely cause. Since you are also lean, hyperactivity of thyroid should also be ruled out.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!

thanks for the info. Just so you know, I'm taking 'Singulair' (10mg of montelukast sodium daily) for allergies. For preventative purposes, my doctor prescribed me to take a puff of a 'Diskus' inhaler a day (50 mcg salmeterol, 250 mcg fluticasone). Also I take 500 mg Vitamin C supplements every morning. Those are the only meds I take routinely.

Also, sometimes I get hot flashes. Even outside in the cold. Although I'm pretty sure that I have a mild anemia, because my sister does too. She found after giving blood and then passed out from lack of oxygen. When I go to the doctor, do you know if there is a way to control my anemia, to the point where my palpitations will disappear for most of the time. It worries me that my heart is gonna way to stressed out from intense beating to the point that one day, I'll have a heart attack or something. Thanks again.
