general practitioners are more capable of discriminating mild disease from normality than they admit to in a referral letter. Only one third of the children had an investigation. This is contrary to suggestions that investigation of every heart murmur is mandatory. In fact, the diagnosis of quiet asymptomatic murmurs is unlikely to be greatly helped by chest radiography or electrocardiography, and echocardiography without Doppler studies is not sensitive in discriminating mild disease from normal anatomy.)
