Speeding then slowing heart beat?

the fluctuation with respirations is normal.  the rest of it i'm not sure about.  if you are unsatisfied with your doc, you might try to find one that will answer your questions better.

PLEASE DO NOT LISTEN TO VK!!! I Have tachycardia and have had to deal with it since 1997, at least that is when it was diagnosed,and it has to do with your sinus node , your hearts electrical system. It is usually treated with beta blockers that have to be taken daily to slow and strengthen the heart. If the problem continues, then there is a procedure called cardiac ablation that will "burn" all of your bad electrical path ways and usually your cured!!

Don't drink! 1st off\n\nYour heart isn't going to stop. you need to go to the doctor and have it checked out and then you will feel better. Are you taking your pulse yourself or have you been told by a doctor that you have a slow heart beat??\n\nWell my heart beats too fast and I get freaked out thinking I'm going to have a heart attack and after all these years I'm still here.\nSo unless you have been told by a doctor you have slow heart rate I wouldn't worry about it.\nJust chill and don't drink. Good lord you wouldn't be able to relax for feeling your heart...:)\nThat was suppose to be funnnny. \nReally I wouldn't drink!\n:)

Does your heart beat funny for a second or two?  If so, I get that.  It's related to anxiety and stress.  I also got it a lot when I smoked or drank caffeine.  Call your doc and make sure it's nothing serious though.

wow this is great..the goal for most people is 30 minutes of cardio activity everyday...so add a minute everyday for a week or so and you'll be there...heart rate shouldn't go much higher...don't know about road speed..use a stationary bike myself...but 13 mph seems as if it would be pretty darned good...good weight for your age...mix it up with other types of cardio so you don't burn out or get bored...

It is impossible to give safe advice based on such limited info. But any irregular heart beat that is "continuous" and makes you feel bad should be evaluated= go NOW

It may be a vagus nerve disorder rather than cardiac.  Go to the internet and read about vaso-vagal fainting to find further information.

To be honest the correct answer is yes and no. Let me explain. If you are taking to proper amount that is perscribed then a slower resting heart rate is a side effect. If you take too much, (I know this is going to sound strange) the effect is actually the opposite. It will speed up your heart rate. And this is very bad!!!!

I also have had them. I am also a medical student just finishing med school.  Those beats you felt are called "PVC's", which in english is a skipped heart beat. You feel it as a racing heart.  This can occur with any "stimulants" like caffine (coke, coffee, red bull), diet pills, decongestents (especially sudafed since it has pseudoephedrine (a stimulant).  \nHowever, you need to have your heart monitored by your own doctor. He will likely give you a "holter monitor" which records your heart over 24 hours.  You should also discuss with your doctor any abnormal or "sudden      s" in your family. \nHope I helped, take care

The lightheadedness and difficulty breating can be side effects of the racing heart. If ur not having panic attacks, u should go to ur dr and find out what is making ur heart race.

I have the feeling sometimes that my heart "skips" a beat.  It's like thump, thump, thump......thump.  I asked my doctor about it, he checked things out with an EKG, etc...and said that it is most likely just normal for me.  It can be brought on by periods of anxiety or stress...try decreasing caffeine.  BUT MOST IMPORTATNLY, IF YOU HAVEN'T CHECKED WITH A DOCTOR YET...DO SO, MAKE SURE ITS NORMAL FOR YOU.

You need to see a doctor, and they will probably either:\n1)Put a 24-hour heart monitor on you if it happens daily.\n2)Put an event recorder on you that you can keep for up to one month to capture the fast heartrate and see what it looks like.\n\nIf you do not have any symptoms such as shortness of breath, low blood pressure, or dizziness during it, that's good.  Still need to find out what it is.\n\nI would see a cardiologist or electrophysiologist, who specializes in abnormal heart rhythms.  They are experts in this stuff.

Yes and it was the scariest thing ever!  My heart started beating faster and faster and faster.  All color drained from my face.  I honestly thought I was going to die!  It stopped on its own but scared the heck out of everyone around me.  I went and had an EKG, everything was normal.
