1. Functional Classification of Heart Disease: Answer Class I: No Limitation. Ordinaryphysical activity does not cause undue fatigue, dyspnea, palpitation, or angina discomfort. Class II: Slight limitation.Comfortable at rest, but ordinary physical activity results in symptoms of fatigue, dyspnea, palpitations, or angina discomfort. Class III: Marked limitation. Comfortable at rest, but less than ordinary activitycauses symptoms of fatigue, dyspnea, palpitation, or angina discomfort. Class IV: Unable to engage in any physical activity without discomfort, and symptoms of cardiac insufficiency are present at rest. 2. S1: Answer Closing of mitral valve with the tricuspid valve(atrioventricular valves) The beginning of systole. 3. S2: Answer Closing of the aortic valve and pulmonic valve.(semilunar valves) 4. Slit S2: Answer may be heard in the second and third left interspaces during inspiration. Fixed S2 split: atrial septal defect and right ventricular failure. Wide S2 split: Delayed closure of the pulmonic valve, pulmonic stenosis and RBBBor early closure of the aortic valve in mitral regurgitation. Paradoxical splitting of S2: occurs only on expiration and is associated with delayedclosure of the aortic valve, LBBB 5. Split S1:
