If you are young, like a teenager or young adult, your heart can handle beating that fast for a short period of time, like during exercise and shortly. In a young person your heart rate should come down back to normal within a minute or two after you stop exercising. If your heart rate goes up to 200 without provocation (aka, you weren't exercising, or otherwise exerting yourself to the point that it would need to beat that fast to compensate for your increased activity for a period of time), like while you are watching TV or something, that IS a sign that something is wrong. This can occur from a birth defect, be chemical induced (if you drank/took too much caffeine or some illegal drugs, for instance), or be idiopathic (no known cause). Either way, it needs to be treated. Your heart cannot sustain that rate for long periods of time. Eventually it will go into failure and be unable to support your body. You won't blow a valve or anything, but what happens is this: In between beats (contractions) the ventricles fill with blood. So when your heart beats that fast your ventricles do not have time to re-fill, and therefore push out less blood with each contraction. Eventually, if the rate stays that high, the heart won't be able to pump out enough blood to circulate and perfuse your system. You will be come confused, tired, cold/pale (possibly blue in your extremities), and eventually pass out. Your heart will eventually be unable to keep up it's pace and will stop, either in V-Fib (ventricles are basically quivering like jello - you can shock this rhythm with a defibrillator) or Asystole, otherwise known as Flatline (not shockable). The key is for a health care professional to fix the fast rhythm with drugs or energy (you can shock a fast heart rate like that to try and convert it to a sustainable rhythm. Don't try that at home!! Medics and doctors ONLY!! lol) But, that's basically what will happen. There are lots of other variable symptoms that come with it too, but nothing will "go out," so to speak. And if it's your heart that's beating that fast - go get it checked dude!!!

is it ok for my heart rate to jump around or over 30bpm briefly after standing up. after a few seconds it goes back down. for example i can be walking around doing stuff and have a heart rate of 90 when my resting is usally 70-80 while awake. it is my understanding that your heart rate needs to STAY over 120, or more than 30 over your resting heart rate while standing to be a problem. also while sleeping my heart rate goes down to 45-60 bpm and when i wake up even shifting around briefly brings my heart rate up allot. could i be hypersensitive to adrenaline or something? This whole thing is causing allot of anxiety and sleepless nights. please let me know if there is anything to worry about. ime 27 male about 6 200lb in ok shape sleeping pills and alcohol elevate my heart rate i some times get wierd beats that my doctor said are ok.

For the past 4 nights i woke up around the same time with a rapid heart beat. I ve been to the cardiologist about this. My EKG and Echo were normal. I also wore a holter but it didn t happen that night but it did show my heart beat per minute as high as 120. The doctor says there is nothing wrong and my heart is healthy but to follow up in a month if it doesn t go away. What do you think is wrong. I am 24 yrs old, 5ft 11 in and weigh 212 lbs.

For the past 4 days, my blood pressure has been running anywhere from 130/95 to 120/102. My blood pressure is usually normal (typically 120/78 or so). I have high cholesterol and a family history of heart disease & am 51. What I don t understand is the numbers being close together. My last reading was 119/102.

I am a 44 year old male with a family history of hyperlipidemia and heart disease. My father had a AMI at age 50 and expired. His father expired at age 51 with an AMi. Both were sudden death. I had a Cardiac CTA yesterday which revealed a calcium score of 252. The report revealed a 70-80% blockage to the middle of the LAD with about 50% occlusion on both of the ends. Seeing a cardiologist tomorrow. What do you think the treatment will be for this?

I recently had an ECG after an abnormal EKG. The ECG showed vent. rate 108bpm Sinus tachycardia, PR interval 158 ms, possible left atrial enlargement, QRS duration 88 ms , nonspecific ST abnormality, QT/QTc 368/493 ms, abnormal ECG, P-R-T axes 70 48 58 and prolonged QT. The cardiologist didn t seem very concerned and felt the abnormality was because of the medication I was taking - remeron for sleeping; I suffer from chronic insomnia. I have been on this medication for over two years and have never had any side effects or problems with it. In the past three-four months, however, I have been experiencing chest pains, some severe which is why I went to my physician to get the first EKG which showed a fast heart beat and was referred to the cardiologist for an ECG, EKG and a stress test. I was only on the treadmill for maybe 4 1/3 minutes before I experienced SOB and chest pains. They repeated the ECG and I was told it was abnormal and to discuss my medications with my psychiatrist and that I had nothing to worry about. When I see abnormal ECG, EKG and am taking nitro tablets with a family history of heart disease (father COPD, CHF and angioplasty; grandfather died of a heart attack), I have a tendency not to believe the doctor. I have not even been contacted by my physician for a follow-up visit. Should I be concerned. Cancer also runs in my family; my father died of colon, liver CA and I am breast cancer survivor. I d appreciate your comments. Should I seek another opinion? Thanks, Mary Kopco YYYY@YYYY I am a 61 y.o. white female, 137 lbs w/ hx of cancer (bilateral mastectomy and hysterectomy for CA of uterus), osteoporosis and osteoarthritis, high cholesterol (328), allergic to any statin drugs, being treated with Zetia 10 mg 1 x/day. Presently taking nitro tabs for chest pain, oxybutityn for overactive bladder, clonazepam 1mg 3x/day for anxiety and depression. I look forward to your response. Thank you.
