Thought Echo: From 1 Different Sources
(echo de la pensée) a symptom of psychosis in which the patient has a hallucination of hearing aloud his or her own thoughts a short time after thinking them.

The latter was an original *Schneiderian first-rank symptom, but has been left out of most translations of Schneider’s work into English.
The use of ultrasonics (see ULTRASOUND) for the purpose of examining the HEART. By thus recording the echo (hence the name) from the heart of ultrasound waves, it is possible to study, for example, the movements of the heart valves as well as the state of the interior of the heart. Safe, reliable and painless, the procedure cuts the need for the physically interventionist procedure of CARDIAC CATHETERISATION.... echocardiography

Echoviruses, of which there are more than 30 known types, occur in all parts of the world. Their full name is Enteric Cytopathogenic Human Orphan (ECHO – hence the acronym). They are more common in children than in adults, and have been responsible for outbreaks of MENINGITIS, common-cold-like illnesses, gastrointestinal infections, and infections of the respiratory tract. They are particularly dangerous when they infect premature infants, and there have been several outbreaks of such infection in neonatal units, in which premature infants and other seriously ill small babies are nursed. The virus is introduced to such units by mothers, sta? and visitors who are unaware that they are carriers of the virus.... echoviruses
