The second heart sound was studied by phonocardiography and carotid tracings in 103 elderly subjects without overt evidence of heart disease. Their ages ranged from 60 to 99 years. A normal type of splitting was found in 55.3 percent, and a single sound in 41.7 percent. The difference between these percentages and those found in 60 normal younger persons was not significant. Thus, a single second sound should not be considered a typical finding in old age. However, a reverse type of splitting, noted in only 3 patients, should be regarded as evidence of severe latent heart disease.
