   Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation ... several muscles, the heart and the respiratory system are all engaged at ...

3. Cardiac conduction system - Wikipedia

   en.wikipedia.org/wiki/Cardiac_conduction_system

   Cardiac muscle has some similarities to neurons and skeletal muscle, as well as important unique properties. Like a neuron, a given myocardial cell has a negative membrane potential when at rest. Stimulation above a threshold value induces the opening of voltage-gated ion channels and a flood of cations into the cell.

4. Bundle of His - Wikipedia

   en.wikipedia.org/wiki/Bundle_of_His

   The bundle of His (BH) [1]: 58 or His bundle (HB) [1]: 232 (/ h ɪ s / "hiss" [2]) is a collection of heart muscle cells specialized for electrical conduction.As part of the electrical conduction system of the heart, it transmits the electrical impulses from the atrioventricular node (located between the atria and the ventricles) to the point of the apex of the fascicular branches via the ...

5. Cardiac action potential - Wikipedia

   en.wikipedia.org/wiki/Cardiac_action_potential

   The action potential passes along the cell membrane causing the cell to contract, therefore the activity of the sinoatrial node results in a resting heart rate of roughly 60–100 beats per minute. All cardiac muscle cells are electrically linked to one another, by intercalated discs which allow the action potential to pass from one cell to the ...

6. Cardiac physiology - Wikipedia

   en.wikipedia.org/wiki/Cardiac_physiology

   Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.

   A lower resting heart rate or slower heartbeat will fill the ventricles/heart better and allow for more of a forceful contraction of blood out to the rest of the body, says Dr. Weinberg.
