Holter
Wearable heart tracker
A Holter monitor is a portable device that continuously records heart activity, typically worn for 24 to 48 hours to detect irregular rhythms that might not appear during a brief office visit: The cardiologist ordered a Holter to catch the intermittent palpitations.
Named for physicist Norman Holter, who developed the technology in the 1960s.
