Question

you are auscultating a patient's chest and you notice that the s2 sound seems to be split, meaning that you can hear two seperate sounds. you can hear a noticeable murmur during s2. Is the abnormality in the atrioventricular valves ot the semilunar valves? how do you know? explain.

Answer 1

sorry but I don't understand your question please write it properly and ask me question of my standard my standard 7th class

Answer 2

Table 1. Wide Physiologic Splitting of the Second Heart Sound

• Delayed pulmonic closure
• Delayed electrical activation of the right ventricle
• Complete right bundle branch block (proximal type)
• Left ventricular paced beats
• Left ventricular ectopic beats
• Prolonged right ventricular mechanical systole
• Acute massive pulmonary embolus
• Pulmonary hypertension with right heart failure
• Pulmonic stenosis with intact septum (moderate to severe)
• Decreased impedance of the pulmonary vascular bed (increased hangout)
• Normotensive atrial septal defect
• Idiopathic dilation of the pulmonary artery
• Pulmonic stenosis (mild)
• Atrial septal defect, postoperative (70O/o)
• Unexplained audible expiratory splitting in normal subject
• Early aortic closure
• Shortened left ventricular mechanical systole (left ventricular ejection time)
• Mitral regurgitation
• Ventricular septal defect

• Table 2. Reversed Splitting of the Second Heart Sound
• Delayed aortic closure
• Delayed electrical activation of the left ventricle
• Complete left bundle branch block (proximal type)
• Right ventricular paced beats
• Right ventricular ectopic beats
• Prolonged left ventricular mechanical systole
• Complete left bundle branch block (peripheral type)
• Left ventricular outflow tract obstruction
• Hypertensive cardiovascular disease
• Arteriosclerotic heart disease
• Chronic ischemic heart disease
• Angina pectoris
• Decreased impedance of the systemic vascular bed (increased hangout)
• Poststenotic dilation of the aorta secondary to aortic stenosis or regurgitation
• Patent ductus arteriosus
• Early pulmonic closure
• Early electrical activation of the right ventricle
• Wolff-Parkinson-White syndrome, type B

i have absolutely no idea but i researched and found this info. hope it helps
