Waht is the maximum and minimum values of heart rate?what is the danger level?


Question:
human beings heart rate 0 is possible for alive ? wat is the possible rate for alive.

Answers:
Maximum and minimum heart rates depends on many factors. General health, age, wieght, body conditioning, etc. Generally the heart rate for an adult is between 75-80 average. People in good health and shape can lower their rate and sustain it for long periods of time. When the heart beats it transports oxygen and other nutrients to tissue through the blood. If cramping occurs in muscles this is an indication that toxins are not being removed through the same process. Maximum rate is aruond 200, again depending on these factors listed. It cannot maintain this rate for a long time because the heart will become fatigued and quit. This is why when training you should monitor your rate. Increasing the rate from resting is good for a cardiovascular workout but dont over do it. The question about a 0 heart rate and being alive, the answer is yes. In heart attack victims their heart stops but tissues and cells still remain alive for a short period of time. However if they dont resume blood circulation they will die due to oxygen not reaching cells and tissues, and toxins not being removed. (signs of rigimortis). So good to be trained in CPR cuz it can happen to anyone at anytime for any reason.
Less than 60 min.
120 max without exercises.
That depends on many factors. A normal resting heartbeat should be about 60 - 70 beats per second. Runners and other athletes have been known to go down into the 50s. People who excersize mind control meditations have been purported to stop the heart rate for up to an hour, but I can not prove that it has been done under modern scientific testing. The maximum is somewhere around 180 - 200 after which the heart just quites from the stress. The heart is capable of sustaining 200 for short periods of time, such as extreme excersize, but it can not maintain it for too long. Pushing the blood that fast also raises the chance of a blow out in an artery, which would be a type of stroke.
