THEPRINCIPLE5 AND PRACTICE OF ECHOCARDIOGRAPHY

Abstract

INTRODUCTION: The development of echocardiography is probably the most important diagnostic advance in cardiology of this decade. Of the many techniques available it most closely approaches the ideal. It provides both qualitative and quantitative information regarding cardiac structure and function. Since ultra sound is non-invasive and at the energy levels used in diagnosis, entirely harmless, examinations may be performed without limitation. The reflected energy is then suitably amplified and recorded on Polaroid film or a strip chart recorder. The latter although expensive, is the most informative means of recording the echo signals.
