Why is it important the heart doesn't get tired?
The heart rests between each beat. As long as the myocardium (heart muscle) receives sufficient oxygenated blood and maintains a proper rhythm, it can (and must) perform this beat/rest cycle throughout and organism's entire life.
What do heart muscles do between each heart beat?
I think they rest but I'm not entirely sure.
Does a fast heart beat at rest mean it is healthy?
The heart might be but the body that it is in certainly isn't.
What is a mark for no sound to count as a beat?
even no sounds counts as a heart beat
Do athletes heart beats faster at rest?

How many times per minute does the human heart beat at rest?

A well-conditioned heart can actually beat as few as times a minute at rest?

What happens to the heart rate with vagal stimulation?
Your heart is able to independently contract without nerve stimulation. However, frequency of these contractions if the heart was not innervated at all would roughly be 100 beats per minute. A resting individual does not need his or her heart to beat that fast to adequately supply blood to the rest of the body. So when at rest the vagus nerve (the branch innervating the heart) kicks in and slows these contractions down so as not to waste energy.
How is heart beat regulated during exercise?
The rate of the heart beat is regulated by the SA node (SinoAtrial Node/aka the Pacemaker). It determines how fast the heart pumps by sending electrical signals faster or slower to the rest of the heart.
How much does your heat beat per minute during rest?
Depends on who you are, what your over all health is, and just what your body does. Mine beats at about 80-90 beats per minute during rest. The way to tell if you're healthy is to measure how long it takes your heart to get under 100 after you have exercised to the point where your heart beat is over 100. The faster the better.
How many times does your heart beat when you are an adult?
The normal heart rate for an adult at rest is between 60 to 100 beats a minute
