Background: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. In addition, the stethoscope is not applicable for continues monitoring, and it is u...

BACKGROUND The ability of medical students to recognize heart murmurs is poor (20%), and does not improve with subsequent years of training. A teaching method to improve this skill would be useful. STUDY OBJECTIVES To determine whether intensive repetition of four basic cardiac murmurs improves auscultatory proficiency in medical students. DESIGN Controlled intervention study. SUBJECTS Fi...

BACKGROUND Cardiac auscultation is a cost-effective, noninvasive screening tool that can provide information about cardiovascular hemodynamics and disease. However, with advances in imaging and laboratory tests, the importance of cardiac auscultation is less appreciated in clinical practice. The widespread use of smartphones provides opportunities for nonmedical expert users to perform self-exa...

Heart diagnosis by phonocardiography and auscultation is highly dependent on experience and there is a considerable inter-observer variation. The complex structure of the Phonocardiogram (PCG) and the variations due to cardiac contractility can generate additional difficulties for auscultation. This review paper focuses on such critical problem solving issues with a variant of analysis. However...

A detailed examination of the cardiac system is essential to a complete physical examination of horses. An understanding of the peculiarities of cardiac auscultation in horses is important in this evaluation. These peculiarities are associated with the large gauge of the equine central cardiac system and high vagal tone. Author’s address: Idaho Equine Hospital, 16080 Equine Dr, Nampa, Idaho 836...

Cardiac auscultation is a highly sensitive, specific, cost effective and comfortable diagnosis technique for many cardiovascular diseases. Unfortunately, it is observed that the art of auscultation is mastered by an increasingly lower number of medical professionals. This paper presents a Matlab tool to support physicians in performing auscultation. This application enables real time signal acq...

Most heart diseases are associated with and reflected by the sounds that the heart produces. Heart auscultation, defined as listening to the heart sound, has been a very important method for the early diagnosis of cardiac dysfunction. Traditional auscultation requires substantial clinical experience and good listening skills. The emergence of the electronic stethoscope has paved the way for a n...
