ANATOMY

Detailed explanation-1: -A heart murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. The sound is caused by turbulent (rough) blood flow through the heart valves or near the heart.

Detailed explanation-2: -In some people, though, the blood makes an extra noise as it flows through the heart. This sound is called a murmur. Doctors hear a heart murmur as a whooshing sound between heartbeats. The whoosh is just an extra noise that the blood makes as it flows through the heart.

Detailed explanation-3: -An S3 gallop or “third heart sound” is a sound that occurs after the diastole S2 “dub” sound. In young athletes or pregnant women, it’s likely to be harmless. In older adults, it may indicate heart disease. An S4 gallop is an extra sound before the S1 systole “lub” sound.

Detailed explanation-4: -Systolic murmur. A heart murmur that occurs during a heart muscle contraction. Diastolic murmur. A heart murmur that occurs during heart muscle relaxation between beats. Continuous murmur. A heart murmur that occurs throughout the cardiac cycle.
