How about the Purjunke fibers How about the bundel of His? - Correct Answer-PR interval Where do PVC originate? - Correct Answer-etopic foci The length of the PR interval in the 1st degree heart block - Correct Answer-< 0.20 or more that 1 big block Why is stress testing performed? - Correct Answer-Stress test is performed: to aid in diagnosis of chest pain to determine the severity and prognosis of CAD to guide post MI rehab to evaluate high risk professional or asymptomatic patient Maximum flow is when the Doppler beam is ? - Correct Answer-parallel to flow What is a typical gradient range for aortic stenosis? - Correct Answer-3.0 -5.0 m/sec What valve lesion has the highest Doppler peak? - Correct Answer-mitral regugitation Doppler equation - Correct Answer-c V= ---------------- f2 2fo cos 0 A patient with a systolic ejection murmur and diminished A2 has? - Correct Answer-Aortic stenosis Most cardiac VSD/ASD shunts are - Correct Answer-left to right due to higher left side pressure. Depending on the shunt volume there will be right side enlargement. If not corrected PHTN may occur - Correct Answer-Eisenmenger's syndrome is the development of PHTN Constrictive pericarditis - Correct Answer-fibrosis, thickening of the pericardium restricting diastolic filling. tamponade - Correct Answer-a hemodynamic diagnosis. Increased intrapericardial pressure caused by impaired ventricular filling and decreased cardiac output. Cor pulmonale - Correct Answer-heart disease secondary to disease of the lungs or pulmonary vasculature. Mitral stenosis murmurs - Correct Answer-are located at the apex or left side Right side murmurs - Correct Answer-are most likely to be affected by respiration Tricuspid regugitation murmurs - Correct Answer-are located closer to the suprasternal notch A pansystolic (holosystic) apical murmur which radiates to the axilla is? - Correct Answer-mitral regugitation Which is louder the first or second heart sound? - Correct Answer-first -- mitral/tricuspid closure What cause the third heard sound? - Correct Answer-rapid, early diastolic flow into a stiff (non compliant) ventricle.
