What is the segment of the cardiac cycle from mitral valve closure to aortic valve closure
Return of the heart muscle cells to their resting state
What is repolarization
The thebesian valve is located?
What is the entrance of the coronary sinus in the RA
Delivers oxygenated blood from the left ventricle to the body
What is the Aorta
The electrical definition of systole
What is the segment of the EKG from onset of QRS to end of T wave
Repolarization occurs from ______ to the _______ (layers of the heart)
What is epicardium to the endocardium
The Right atrium receives deoxygenated blood from... name all 3
What is SVC, IVC and coronary sinus
Receives systemic venous return from the SVC (upper extremities, head, neck) and IVC (lower extremities, abdomen, portal system) and receives most of the coronary venous return from the coronary sinus.
What is ascending aorta, aortic arch, descending aorta, abdominal aorta
During early systole this causes the mitral valve to close
What is when the left ventricular pressure exceeds left atrial pressure
Normal sinus rhythm
What is 60-100 bpm
