Ans. is 'd' i.e., Increase on squatting A continuous murmur is defined as one that begins in systole and extends through S2 into pa or all of diastole. It need not occupy the entire cardiac cycle. Continuous murmurs are not affected by dynamic auscultation maneuvers like squatting etc. They can oftern be difficult to distinguish from individual systolic and diastolic murmurs in patients with mixed valvular hea disease. The classic example of a continuous murmur is that associated with a patent ductus aeriosus, which usually is heard in the second or third interspace at a slight distance from the sternal border.
