Among the new diagnostic methods in cardiology, echocardiography is certainly the most informative. The field has grown so rapidly in recent years that it is almost impossible to keep up with the new technical developments and their application in patient care. The principle of the method is based upon the detection of echoes produced by a beam of short ultrasound pulses transmitted into the heart. Ultrasound is harmless at the energy levels used. The examination can thus readily and repeatedly be used without untoward effects to the patient making it the ideal method for serial analysis and follow-up studies.
