摘要

The stethoscope is an air-filled tube that conducts sound. It replaced the direct placement of the ear on the chest more than 200 years ago. We now have two-dimensional ultrasound allowing us to visualize cardiac structure and function in real time. The addition of Doppler has also facilitated the assessment of blood flow through the cardiac chambers and great vessels. Over the past decade, smaller and smaller ultrasound devices have been designed, such that we now have devices that fit in the pocket of a white coat. These devices have been tested against standard high-end echocardiography systems and found to be comparable in their ability to detect important cardiac abnormalities. It is also possible to train novices in the use of these devices to exclude major cardiac abnormalities. Many medical schools now use these devices in order to train students in point-of-care ultrasound for many medical and surgical conditions, including those that affect the heart. The question is whether these devices will gradually replace the stethoscope for point-of-care evaluation of patients.
