Chamber that pumps oxygenated blood into the systemic circulation.
The myocardium is the thickest in this chamber.
Hardest working chamber.
Collection of fluid or blood in this space causes an external compression of the heart called (cardiac tamponade)
Semilunar valve through which blood leaves the right ventricle.
Valve that prevents the backflow of blood from the pulmonary artery.
Exit valve that sees only unoxygenated blood.
Atrioventricular valve on the right side of the heart.
Entrance valve that sees only unoxygenated blood.
Called the Mitral valve.
Entrance valve that sees only oxygenated blood.
Valve that prevents the backflow of blood from the left ventricle.
Atrioventricular valve between the left atrium and the left ventricle.
The first heart sound (lubb)
Heart sound created by the closure of the AV valves to the ventricular walls.
Heart sound created by the closure of the semilunar valves at the beginning of ventricular relaxation.
Exit valve that only sees oxygenated blood.
Valve that prevents the backflow of blood into the left ventricle.
Semilunar valve through which blood leaves the left ventricle.
Life-threatening dysrhythmia that causes the ventricular myocardium to quiver in an uncoordinated and ineffective way.
Bundle of HIS
Specialized conduction tissue in the interventricular septum.
Divided into the right and left branches.
These fast-conducting fibers spread the electrical signal throughout the ventricular wall.
ECG deflection that indicates atrial depolarization.
Electrical event that stimulates atrial contraction
ECG deflection that indicates ventricular depolarization.
Electrical event that stimulates ventricular myocardial contraction.
