Heart

QuestionAnswer
transverse pericardial sinus allows access to pass ligatures around aorta & pulmonary trunk
Pericarditis inflammation of pericardium
Pericarditis pain located at top of shoulder b/c sensory innervation of pericardium from phrenic n. (friction heard w/stethoscope)
Cardiac tamponade accumulation of fluid inside pericardium puts pressure on heart & makes it difficult to pump blood
R. atrium contains pectinate mm., crista terminalis, sinsus venarum, fossa ovalis, ostium for coronary sinus
R. ventricle contains tricuspid valve, chordae tendinae, papillary mm., septomarginal trabeculum(moderator band), conus arteriosus, pulmonary valve
R. ventricle experiences hypertrophy when vascular resistance in lung is high as w/COPD
L. ventricle contains thickest wall, mitral valve, chordae tendinae, papillary mm., aortic valve
L. ventricle experiences hypertrophy in congestive heart failure
R. Coronary a. contains SA nodal, R. marginal, AV nodal, posterior interventricular
L. Coronary a. contains (SA nodal), anterior interventricular aka "LAD", circumflex
Great cardiac vein runs with anterior interventricular a.
Middle cardiac vein runs with posterior interventricular a.
Small cardiac vein runs with right marginal a.
Cardiac sinus recieves drainage from great, middle, small cardiac vv.
Cardiac sinus opens into r. atrium
anterior cardiac v. drains directly into r. atrium
single lymphatic vessel drains lymph from heart to inferior tracheobronchial nodes
Sinoatrial (SA) node located in wall of r. atrium at end of crista terminalis
atrioventricular (AV) node located on floor of r. atrium next to septum
AV node transmit signal to inferior aspect of ventricles via r. & l. bundle branches.
Moderator band has many fibers from the r. bundle pass through it
Heart Sympathetics preganglionic and postganglionic fibers
Preganglionic fibers exit from T1-T4
Postpanglionic fibers located in local chain ganglion & inferior (stellate), middle, & superior cervical ganglia
Heart Parasympathetics from vagus n.
Cardiac Plexus Superficial & Deep
Superficial Cardiac Plexus anterior to arch of aorta & projects mainly to l. ventricle
Deep Cardiac Plexus near bifurcation of trachea, projects mainly to posterior, Right SA node
Surface anatomy of heart superior border from inferior border of 2nd costal cartilage to right of sternum to top of 3rd costal cartilage on left (2nd intercostal space: hight on right, low on left)
Inferior heart surface anatomy inferiorly from 6th costal next to sternum on right passing along xiphisternal junction at midline
Apex located in 5th intercostal space near midclavicle line
Atrial Septal Defects (ASDs) result of incomplete closure of fossa ovalis & small ones (probe patent)
Atrial Septal Defects (ASDs) occur in about 1/5 of population
Ventricular Septal Defects (VSDs) most common heart malformations
Ventricular Septal Defects (VSDs) occur btwn. membranous & muscular portion of septum. Cause a L. to R. shunt which may result in pulmonary hypertension
Mitral valve most commonly damaged
Mitral valve damage due to rheumatic fever
Mitral valve damage results in incomplete closure results in backflow
Murmur backflow is audible through stethoscope at apex of heart referred to as a murmur
Aortic valve problems cause collapsing pulse w/characteristically high pulse pressure (difference btwn. systolic & diastolic BP)
Coronary Artery Disease impaired blood flow to heart due to atherosclerosis & may cause angina pectoris (chest pain)
Sudden occlusion of coronary vessel produces ischemia (lack of sufficient blood)
Ischemia of heart may result in death of heart m.
myocardial infarction (MI) heart attack
common site of infarct vascular tree of LAD
infarction involving AV node atria continu in normal rhythm, but ventricle beat at slower inherent rate w/no coordination of function
Bundle branch block unaffected side beats firts then impulse passes to other side causing temporal separation of ventricular contraction
