Intracardiac sound and pressure: right heart events. Toward an ultimate classification of auscultatory events.

: These observations are presented as a tentative step towards an ultimate classification of auscultatory events based on ICSP studies, chest wall phonocardiography, and auscultatory areas, with continuing clarification or modification by angiography, Doppler techniques, echocardiography, computer usage, and any available, useful technique. The ultimate diagnostic value of ICSP information resides in the feed-back loop wherein this information is used daily at the bedside as part of the understanding and explanation of daily auscultatory phenomena.
