K+ ions rush out of the cell‚ and the net result is rapid repolarization that restores the resting potential. ATRIAL DIASTOLE/ VENTRICULAR SYSTOLE. During atrial repolarization‚ the ventricles are depolarizing (seen as the QRS on the EKG) because the impulse has passed the AV node‚ travelled along the septum within the bundle of His‚ down the bundle branches and Purkinje fibers.

STROKE A stroke—also called a cerebrovascular accident (CVA) or a brain attack—is an injury to the blood vessels of the brain that causes neurological malfunctioning. In the United States‚ as many as 87% of all strokes are caused by the sudden blockage of a cerebral artery. The resulting decrease in blood flow leads to ischemic damage in the region of the brain that is fed by the artery. These CVAs are called ischemic strokes. Most ischemic strokes are due to blood clots. The remaining 13%

Systemic Arterial Blood Pressure is the force of blood pressure on the arterial walls just after ventricular contraction. Cardiac output is the volume of blood ejected from the left or right ventricle into the aorta or pulmonary trunk per mind. Cardiac output equals stroke volume times the heart rate; therefore‚ if the anything that decreases cardiac output

the closing of the Atrioventricular valve caused by ventricular contraction. The R wave occurs during the depolarization of the ventricles. Hence the lub sound occurs because of both the depolarization and consequently the closing of the AV valves which prevent blood flow back into the atria.
