The heart is a pump made of muscle tissue. Its pumping action is regulated by electrical impulses.
The American Heart Association explains that arrhythmia refers to any change from the normal sequence of electrical impulses, such as atrial ...
The third order of electrical influence of the heart is derived from the vagus nerve as the other peripheral organs form. Function[edit]. Action potential generation[ ...
Thus, the electrical signals cause the mechanical pumping action of the heart.
Even though cardiac muscle has autorhythmicity, heart rate is modulated by the ... the action potential (the electrical impulse) that travels throughout the heart and ... In order to speed up the heart rate and restore full sinus rhythm, a cardiologist ...
Sequence of Cardiac Electrical Activation. conduction velocities in the heart. The action potentials generated by the SA node spread throughout the atria ...
Second, by measuring the amount of electrical activity passing through your heart muscle, a cardiologist may be able to find out if parts of the ...
