echocardiography [‚ek·ō‚kärd·ē′äg·rə·fē] (medicine) A diagnostic technique for the heart that uses a transducer held against the chest to send high-frequency sound waves which pass harmlessly into the heart; as they strike structures within the heart, they are reflected back to the transducer and recorded on an oscilloscope.

Patients appeared to have chronic, blood culture-negative endocarditis; fever was usually present (90%), a vegetation was usually observed on echocardiograph (90%), and >90% of patients required valvular surgery. Rotary clubs here and abroad raised $30,000 for an echocardiograph machine that uses ultrasound to visualize the internal structure of the heart. Key features of the MedVizer Tele-Echocardiography solution include capabilities for transferring and displaying diagnostic-quality echocardiographs that enable cardiologists to remotely diagnose or exclude heart disease in infants, children, and adults, especially those who would not otherwise have immediate access to cardiac specialty care. |
