Cardiac muscle never rests.
If it ever did rest for one beat, its resetting its pulse. but if it happens too frequently, then there's a problem. if a heart did rest completely, you die. (in other words, you get a heart arrest.)

Function of the cardiac muscle?
Cardiac muscle tissue is the tissue that makes up the bulk of your heart and when it contracts it will squeeze blood to your lungs through the pulmonary circuit, and to the rest your body through the systemic circuit.
Is a heart a cardiac muscle?
Unlike other types of muscle, cardiac muscle never gets tired. It works automatically and constantly without ever pausing to rest. Cardiac muscle contracts to squeeze blood out of your heart, and relaxes to fill your heart with blood. Unlike skeletal muscle tissue, its contraction is usually not under conscious control
Are cardiac muscles prokaryotes?
No, cardiac muscle is eukaryotic just like the rest of the cells in an animal.
If cardiac muscle never tires if you eat it do your other muscles absorb it and never tire aswell?
in the cardiac cicle, the cardiac muscle work the same time as it rest. is not true that never tires. and if you eat meat, at the end only give to the bodye aminoacids, the cardiac tissue need glucose and oxigen EVERY time it works! otherwise harth attack is available.
What tissue is most metabolically active at rest?
Muscle
What Special tissue in right atrium that regulates heartbeat?
Sino-atrial node(SA node), it's also called natural Pacemaker.
What is cardiac rest?
its not cardiac rest, its cardiac ARREST. which is a heart attack.
Which ventricle has more cardiac muscle?
The left ventricle has more muscle because it pumps blood to the rest of the body, the right ventricle only pumps blood to the lungs which is a lot closer.
Does the cardiac muscle contract rythmically yes or no?
In a healthy heart at rest , yes . The pulse should be steady with equal spacing between the heartbeats.
What is resting cardiac output?
its not cardiac rest, its cardiac ARREST. which is a heart attack.
Why cardiac cells do not divide?
Cardiac tissue is a very special type of muscle tissue in that it acts like muscle AND like nerve, in order to allow for the wave of contraction to spread from one part of the heart to the other after the SA node (pacemaker) signal is received, allowing for the proper pumping action throughout the heart chambers. If cardiac muscle were allowed to divide, then branched structures of cardiac muscle could form, which could interfere with this carefully regulated contraction wave, and it could result in fibrillations. This very situation happens quite often after a myocardial infarction (blockage to the coronary arteries leading to heart attack) results in some damage to cardiac muscle, and then medical intervention allows for the person to be resuscitated. While the some of the cardiac muscle dies due to lack of oxygen supply to the cells, when oxygenated blood supply is returned, and pulse is restored, some of the cells that were inactive for a while can begin beating out of rhythm with the rest of the heart, resulting in a contraction wave that works against the overall contraction wave of the heart, leading to fibrillations (irregular contraction waves moving across the heart, not in sync with one another)...which results in no proper flow of blood into and out of the heart...requiring defibrillation to stop all cardiac contraction, allowing the brain to restart the heart and restore proper cardiac rhythm.
Why does cardiac muscle never become tired?
blc cardiac muscles ve long refractory factor
