heart and great vessels - INCOMPLETE Flashcards
coronary arteries: describe the origin, course and main branches of the left and right coronary arteries and discuss the functional consequences of their obstruction in conditions such as ischaemic heart disease
what is the more common variation in coronary arteries
right dominant coronary artery; posterior interventricular branch arises from right coronary artery; marginal; circumflex
what is the less common variation in coronary arteries
left dominant coronary artery; posterior interventricular branch arises from left coronary artery
what is a myocardial infarction
blood issue causing ischaemia
what is a cardiac arrest
not due to ischaemic - electrical
coronary veins
follow arteries, drain into coronary sinus (IVC of heart - bringing back deoxygenated blood from heart)
when are coronary arteries perfused with blood
systole - valves shut so blood forced into coronary arteries also
when is blood pushed around coronary arteries
diastole - valves open and force blood through arteries
