Telectronics 5012 Chronocor VI External Pacer

The Telectronics 5012 Chronocor VI External Pacer is a portable external cardiac pacer designed for temporary atrial or ventricular pacing during emergency care, cardiac surgery, and postoperative recovery. It provides temporary single- and dual-chamber pacing (configuration dependent) with adjustable output pulse amplitude and pulse width, an adjustable pacing rate, and demand sensing with selectable sensitivity. Front-panel controls manage pacing parameters and monitoring, and integrated indicators display pacing status and battery condition, while the unit is powered by an internal battery-operated portable power source. Manufactured by Telectronics Pacing Systems as a genuine Telectronics device (Model Chronocor VI, Part Number 5012), it is used for temporary cardiac pacing in emergency medicine, surgery, intensive care, and electrophysiology laboratories. Common replacements include Medtronic 5388 Dual Chamber Temporary External Pacemaker, Medtronic 5348 Temporary External Pacemaker, and Oscor Pace 203H External Cardiac Pacemaker.
