Popis: | Phonocardiograms were obtained of 30 normal men in the supine and sitting positions. They demonstrated significantly greater S2 splitting and respiratory variation in S2 in the sitting position. However, several individuals showed wider splitting or greater variation while supine. Fixed splitting occurred in three subjects while supine and five others while sitting, but in no normal subject was splitting fixed in both positions. |
