What is the usual difference between jugular venous pressure and right atrial pressure and why? Usually right atrial pressure is more than jugular venous pressure by 5 cm
What is the cause of central cyanosis in Osler-Weber-Rendu syndrome? Central cyanosis in Osler-Weber-Rendu syndrome is due to pulmonary arteriovenous fistula. Those with Osler-Weber-Rendu syndrome or hereditary hemorrhagic
What causes a prominent a wave in jugular venous pulse? Prominent a wave occurs when the right atrial contraction is more forceful due to increased resistance to right
When does the y descent in jugular venous pulse occur? y descent in jugular venous pulse occurs with decline of right atrial pressure when the tricuspid valve opens.
What happens to the amplitude of jugular venous pulsations in inspiration? Jugular venous pressure normally declines during inspiration, but the amplitude of the pulsations increases. An inspiratory increase in
In which situations are stress echocardiography useful? Stress echocardiography is useful when exercise stress test is not feasible due to mobility issues. Stress echocardiography is usually done with
What is the maximum speed at which BP cuff can be deflated while measuring blood pressure? Maximum speed at which BP cuff can be deflated while measuring blood
What is the mechanism of decubitus angina? Increase in venous return and consequent increase in preload on assuming the supine position is the reason for decubitus angina. Most
Why is angina not a typical symptom of left ventricular aneurysm? Angina pectoris indicates viable but ischemic myocardium. In ventricular aneurysm, it is usually a non-viable scarred area
What are the mechanical complications of acute myocardial infarction? Typical mechanical complications of acute myocardial infarction are rupture of papillary muscle, rupture of interventricular septum and rupture of
