Origin of the third heart sound.
We report noninvasive and invasive studies designed to clarify the mechanism of the third heart sound (S3) in humans. The noninvasive observations were made using a miniature accelerometer attached to the skin surface at the cardiac apex. In subjects with no S3, the tracings were either flat or showed very low undulations throughout diastole. Those with an S3, however, demonstrated a distinct r...
متن کاملMechanical correlates of the third heart sound.
In seven chronically instrumented conscious dogs, micromanometers measured left ventricular pressure, and ultrasonic dimension transducers measured left ventricular minor-axis diameter; the latter recording was filtered to examine data between 20 and 100 Hz. Acceptable external heart sounds were recorded with a phonocardiographic microphone in four of the seven dogs. With each dog sedated, intu...

متن کاملThe third heart sound for diagnosis of acute heart failure.
Dyspnea is a common presenting complaint in the emergency department (ED). Rapid identification of heart failure as the etiology leads to early implementation of targeted therapies. Although having only intermediate sensitivity, the S3 is a highly specific finding among older adults with heart failure. Identification of an S3 by routine auscultation can be problematic given the chaotic and nois...
متن کاملThird heart sound after mitral valve replacement.
Seven patients have been described who developed a third heart sound in association with a paravalvar leak around a Starr-Edwards mitral valve prosthesis. These patients had all had the mitral valve cusps, chordae tendineae, and part of the papillary muscles excised. The presence of a third heart sound in them supports the concept of Potain (I900) that the third heart sound arises by vibrations...
