Abstract

An apparatus to enable health care providers to perform a number of diagnostic procedures, including listening to the heart, obtaining electrocardiograms and sonograms. A pocket size instrument displays an EKG tracing on its screen simultaneously upon auscultation of the heart. The abdomen may also be investigated by displaying a sonogram. Wireless broadband technology may provide a closed circuit interface for real-time wireless transmission of acquired data. Examination requires none of a multiplicity of wires to untangle, bulky machines or a technician to be summoned. Regurgitation, heart size, ischemia and heart murmurs can all be evaluated by a visual and auditory methods.
