متن کاملNew technology in echocardiography I: Doppler techniques.
Ultrasonic technology is in several ways ideally suited to cardiac research and to routine clinical examinations. It provides truly real time images and detailed information on moving anatomical structures and blood. The portable nature and relatively low cost of the equipment makes it well suited to use in hospitals. Ultrasonic technology for cardiology is still developing and in recent years ...
متن کاملDobutamine stress echocardiography.
Two-dimensional echocardiography is a versatile, accurate, and readily available method for the assessment of cardiac anatomy and function, and extensive experience has been gained in the analysis of left ventricular wall motion. Using modern imaging techniques, regional as well as global wall motion analysis can be performed. Echocardiography can be used in conjunction with a protocol for eith...
متن کاملTransoesophageal stress echocardiography.
Transoesophageal echocardiography has been performed in conjunction with pacing, dobutamine, or dipyridamole stress to detect stress-inducible ischaemia, and has proved to be a highly accurate diagnostic tool. Its advantages of improved image quality and high diagnostic accuracy have to be weighed against the disadvantages of semi-invasiveness and patient discomfort. The existing data on this s...
متن کاملPacing stress echocardiography
BACKGROUND High-rate pacing is a valid stress test to be used in conjunction with echocardiography; it is independent of physical exercise and does not require drug administration. There are two main applications of pacing stress in the echo lab: the noninvasive detection of coronary artery disease through induction of a regional transient dysfunction; and the assessment of contractile reserve ...
