What is the contractive phase of the heart called?
Systole
Systole is the contraction phase of the cardiac cycle, and diastole is the relaxation phase.
What is the initiation of heartbeat?
The heart’s electrical system Your heartbeat is triggered by electrical impulses that travel down a special pathway through your heart: SA node (sinoatrial node) – known as the heart’s natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node.
What is the isovolumetric contraction phase?
In cardiac physiology, isometric contraction is an event occurring in early systole during which the ventricles contract with no corresponding volume change (isometrically). This short-lasting portion of the cardiac cycle takes place while all heart valves are closed.
What is the contraction phase of Oracle is called?
The phase of cardiac cycle in which the auricles contract is called Auricular Systole.
What does the SA node do?
An electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node). This is a small mass of specialized tissue located in the right upper chamber (atria) of the heart. The sinus node generates an electrical stimulus regularly, 60 to 100 times per minute under normal conditions.
What is the diastole phase?
diastole, in the cardiac cycle, period of relaxation of the heart muscle, accompanied by the filling of the chambers with blood. Diastole is followed in the cardiac cycle by a period of contraction, or systole (q.v.), of the heart muscle.
What is the contractive phase of the heart cycle?
Contractive phase of the heart cycle during which blood is forced into the systemic circulation via aorta and the pulmonary circulation via the pulmonary artery. Tachycardia Rapid heartbeat that is over 100 beats per minute

What does systole mean in the heart?
Systole Contractive phase of the heart cycle during which blood is forced into the systemic circulation via aorta and the pulmonary circulation via the pulmonary artery. Tachycardia Rapid heartbeat that is over 100 beats per minute
What is congestive heart failure?
Pathological condition in which the heart loses its ability to pump blood efficiently. Left-sided heart failure is commonly called congestive heart failure. Hemangioma Benign tumor of a blood vessel
