Cardiac murmurs Cardiac murmurs are often the first sign of underlying valvular disease May be systolic or diastolic, pathological or benign. Systolic murmurs may be due to physiological increases in blood velocity or might indicate as yet asymptomatic cardiac disease Diastolic murmurs are usually pathological and require further evaluation ECG and CXR are readily available, but provide limited informationCardiac murmurs • Cardiac murmurs are often the first sign of underlying valvular disease. • May be systolic or diastolic, pathological or benign. • Systolic murmurs may be due to physiological increases in blood velocity or might indicate as yet asymptomatic cardiac disease. • Diastolic murmurs are usually pathological and require further evaluation. • ECG and CXR are readily available, but provide limited information
