Ascending Aorta - ANSWER -begins from the aortic valve and extends from the left ventricle of the heart to the aortic arch.
-Supplies the Coronary Arteries
Aortic Arch - ANSWER Supplies the Brachiocephalic Artery,
Left Common Carotid Artery, and the Left Subclavian Artery
Descending Aorta - ANSWER major portion of the aorta that extends from the aortic arch to the trunk of the body. It forms the thoracic aorta and abdominal aorta.
Coronary Arteries and the myocardium are perfused during - ANSWER diastole
P- wave represents - ANSWER atrial depolarization
Q wave represents - ANSWER beginning of ventricular depolarization
Inferior chest leads - ANSWER II, III, aVF
RCA occlusion
Anterior chest leads - ANSWER V3, V4
LAD occlusion
Septal chest leads - ANSWER V1, V2
LAD occlusion
Lateral chest leads - ANSWER I, aVL, V5,V6
Circumflex occlusion
T wave represents - ANSWER ventricular repolarization
Sympathetic nervous system releases - ANSWER norepinephrine ( causes pupil dilation, increased sweating, increased heart rate, and increased blood pressure)
Parasympathetic nervous system releases - ANSWER acetylcholine (decreases heart rate, decreases blood pressure, pupils constrict, increases digestion and urinary output)
RCA supplies - ANSWER Right atrium, right ventricle, SA/AV nodes, posterior portion of right bundle branch
Occlusion causes AV blocks and bradycardias
Circumflex artery supplies - ANSWER side wall of the left ventricle and posterior portion of Left bundle branch
LAD supplies - ANSWER Anterior portion of heart, portion of the septum, left ventricle, left bundle branch
Occlusion causes BBB's, Vtach, Vfib
Peripheral vascular resistance - ANSWER a resistance to the flow of blood determined by the tone of the vascular musculature and the diameter of the blood vessels.
It is responsible for blood pressure when
