Diuretics is not the right answer. It is cardiotonic.
digitalis , digoxin
cardiac glycosides
Digitalis
fibrillation
the lungs and the legs contract the heart for regular pulse that murmurs
Arrhthmyia of the heart, problems with smooth and skeletal muscle contractions; hyperkalemia can even stop the heart muscle.
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
cardiotonics increase the strenght of the muscle contractions that pump blood from the heart.
the cardiac muscle is your heart. you tell me. ever heard of cardiac arrest? its also called a heart attack.
a small group of cardiac muscle cells that "set the pace" for the heart as a whole and they begin each contractions.
Yes. If strong enough, the electric current can cause intense muscle contractions. The muscle contractions can fatigue the muscle, depleting it of nutrients and electrolytes. When that happens, the muscle is incapable of functioning, and if the muscle happens to be your heart, you die. CPR can be helpful because it brings nutrients back to the heart muscle and provides sufficient blood flow to keep the individual alive until the heart can start again. In general, the effects of electric shock are immediate. If the voltage and current are high enough, an electric shock can burn tissue causing permanent damage.
Isovolumetric contraction and Isovolumetric Relaxation
The contractions start from a node in the myocardiumcalled the SA node (sino-atrial node), which produces the stimulatory signals in a rhythmic mode. As the stimulatory signals move throughout the myocardial muscle, it contracts.
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
The central nervous system supplies the body and muscle contraction. Striated muscle (skeletal muscle) contract voluntary with exception of the heart which is striated involuntary smooth muscle.
