Beck's triad

Full Definition

A constellation of three clinical findings that together suggest cardiac tamponade, named after Claude Beck. The triad consists of elevated jugular venous pressure, systemic hypotension, and muffled or distant heart sounds. While historically significant for diagnosis, Beck's triad is present in only a minority of tamponade cases, making it an unreliable sole diagnostic criterion. Modern emergency cardiology relies more heavily on echocardiographic findings, but the triad remains important for clinical recognition and medical education.

Usage

Usage note: Possessive form 'Beck's' should always include the apostrophe in formal medical documentation.
