Physiological Consequences of Elevated Pulmonary Artery Pressure Flashcards
1
Q
What causes right ventricular heave?
A
A forceful right ventricle contraction due to pulmonary hypertension
2
Q
What causes a tricuspid pan systolic murmur in pulmonary hypertension?
A
Functional tricuspid incompetence due to right ventricular dilation
3
Q
What is ascites?
A
Increased fluid within the peritoneal cavity due to oedema
4
Q
What are the causes of pulmonary hypertension?
A
Increased left atrial pressure, increased pulmonary blood flow, increased pulmonary vascular resistance
5
Q
What causes increased pulmonary vascular resistance?
A
Destruction of pulmonary capillaries, constriction of pulmonary arterioles, blockage of pulmonary vessels
