- 1What are supplied by branches of the RCA?SA and AV nodes are supplied by branches of the RCA.
- 2SA and AV nodes are supplied by what?By branches of the RCA.
- 3Infarct may cause what?Infarct may cause nodal dysfunction
(bradycardia or heart block) - 4What supplies the right ventricle?Right (acute)
marginal artery
supplies right
ventricle - 5What supplies lateral and posterior walls of left ventricle, anterolateral papillary muscle?Left circumflex coronary
artery (LCX) - 6What does Left circumflex coronary artery (LCX) supply?Supplies lateral
and posterior walls of left
ventricle, anterolateral papillary
muscle - 7What does Right acute marginal artery supply?Supplies right
ventricle - 8What supplies supplies anterior 2/3 of interventricular septum, anterolateral papillary muscle, and anterior surface of left ventricle?Left anterior descending
artery (LAD) - 9What does Left anterior descending artery (LAD) supply?Anterior 2/3
of interventricular septum,
anterolateral papillary muscle,
and anterior surface of left ventricle - 10What supplies AV node, posterior 1/3 of interventricular septum, 2/3 posterior walls of ventricles, and posteromedial papillary muscle?Posterior descending/interventricular artery (PDA)?
- 11What does Posterior descending/interventricular artery (PDA) supply?supplies AV node, posterior 1/3 of interventricular septum, 2/3 posterior walls of ventricles, and posteromedial papillary muscle
- 12Which type of circulation? 85%Right-dominant
- 13Which type of circulation? 8%Left-dominant circulation
- 14Which type of circulation? 7%Codominant circulation
- 15Which type of circulation? PDA arises from RCA.Right-dominant circulation (85%)
- 16Which type of circulation? PDA arises from LCX.Left-dominant circulation (8%)
- 17Which type of circulation? PDA arises from both LCX and RCA.Codominant circulation (7%)
- 18In co-dominant circulation (7%), PDA arises from what?Codominant circulation (7%) = PDA arises
from both LCX and RCA. - 19In Left-dominant circulation (8%), PDA arises from what?Left-dominant circulation (8%) = PDA arises
from LCX. - 20In Right-dominant circulation (85%), PDA arises from what?Right-dominant circulation (85%) = PDA arises from RCA.
- 21Coronary artery occlusion most commonly occurs in what?Coronary artery occlusion most commonly
occurs in the LAD. - 22When does coronary blood flow peak?Coronary blood flow peaks in early diastole.
- 23What is the most posterior part of the heart?The most posterior part of the heart is the left atrium.
- 24Enlargement of the left atrium can cause what? Why?Enlargement can cause dysphagia (due to
compression of the esophagus) or hoarseness (due to compression of the left recurrent laryngeal nerve, a branch of the vagus). - 25What are the three layers of pericardium from outer to inner?Fibrous pericardium
Parietal layer of serous pericardium
Visceral layer of serous pericardium - 26How many layer of pericardium?T
- 27What is the outer most layer of Pericardium?Fibrous pericardium
- 28What is the inner most layer of Pericardium?Visceral layer of serous pericardium
- 29What is the middle later of Pericardium?Parietal layer of serous pericardium
- 30What lies between the parietal and visceral layers?Pericardial cavity lies between parietal and visceral layers.
- 31Where does the Pericardial cavity lie?Pericardial cavity lies between parietal and visceral layers.
- 32Pericardium is innervated by what?Pericardium innervated by phrenic nerve.
- 33Pericarditis can cause referred pain to what?Pericarditis can cause referred pain to the shoulder.
- 34What is the most posterior part of the heart?The most posterior part of the heart is the left atrium
