You shouldn't be asking that here ! If it's your child - you should be seeking professional medical help - not relying on unqualified answers on a website !
It depends on your age, as it depicts how fast your heart can beat at it's maximum. This number is usually around 180+, depending on how old you are. if your heart is beating over that, then you are putting a major strain on your heart.
If your heart is beating 120 times a minute when you're at rest, I suggest you see a Doctor. That said, at that rate your heart will beat over 63 million times in a year.
only one heart is ever in a baby, beating or not beating.. Oh wait did you mean how many beats per minute does a baby's heart beat? if that's the question the answer is SEARCH BEFORE YOU ASK
Shrews live a short, but busy, life, the heart rate can be 1000 beats/minute. Few live longer than 1.5 year.
If you wake up suddenly, or from nightmares, it is quite normal to have a fast heart rate. If it isn't these, then, yes, you might be right to worry. A doctor should be able to help you determine exactly what is causing the increased heart rate. ____________________________________________________________________ You could be having heart palpitations. Palpitations are usally of no importance unless symptoms occur For more information follow my link::: http://wiki.answers.com/Q/How_heart_works&alreadyAsked=1
Yes. Go.
Hey there. I'm a fourth year medical student and probably not fully qualified to answer this question, but I'll do my best. First off, following a heart attack, usually the heart continues to beat, although it may beat less effectively, or develop an arythmia. If the heart actually stops beating, this is called asystole. Asystole is rare, and once a person has entered asystole, it is very hard to restart their heart. It is generally a confirmation of death, rather than a condition that is considered treatable. Defibrillating an asystolic heart is unlikely to be helpful. So to answer your question, no, if a heart has stopped beating for thirty minutes, it usually cannot be restarted. In fact, the timeframe for restarting a heart that has stopped beating is only around 90 seconds to 5 minutes, and even within this time, restarting an asystolic heart is rarely successful. The exception to this is if the person whose heart has stopped is given really good CPR from the moment that their heart stops beating, in order to maintain blood supply to the heart. This can extend the timeframe in which an unbeating heart is restarted. In addition, if the unbeating heart is chilled to a near freezing temperatures (ie, removed from the chest), this can slow down the death of cardiac tissue and again prolong the survival of cardiac tissue so that it can still be restarted after 30 minutes.
No, puppies are very friendly and learn fast. If your puppy is mean then there has to be a reason

Have the boy checked for White Parkinsons Wolf Syndrome. That is when you have two triggers that make your heart beat instead of one.
