yes, because heart is one of the main function of our body if our heart is not automatically function we can automatically died.
pacemaker controlls the heart beat and etc
medulla oblongata
When a heart is said to be in fibrillation it means that it has lost its rhythm and is basically quivering. Automatic external defibrillators (AED) provide an electric shock to the heart which has been known to get it back to its usual rhythm.
The automatic nerve response is from the system which controls the involuntary autonomous functions of the body. Breathing and heart beats are examples of these.
I believe it is the ventricles. It collects and expels blood. It is like an automatic door that closes and shuts itself.
medulla
The heart runs on an automatic system just as breathing does. The heart's built-in electrical system controls the speed of its pumping. The electrical impulse originates in the sinus node which functions as the heart's natural pacemaker.
There is no such tissue, the heart can beat automatically, without an external stimulus, it has several groups of automatic cells that discharge electricity currents that make the muscle cells in the heart beat sinchronically. Also, this automatic beat can be slowed down or can be made quicker by influences of autonomous nervous system, but remember, it can work by itself. It is called an involuntary muscle.
No, they are two seperate awards with different award criteria.
Nervous system, with the help of endocrine.
No--however they are affected by magnets and Xrays.
No, manual measurements of heart rates done by professionals are better in detecting irregularities. An Electrocardiogram (ECG) machine can get accurate readings as well.
