Processing of Holter Monitors

Holters are scanned at our main laboratory. The scanned Holters are then forwarded to a Cardiologist/Internist of the physician’s choice for interpretation. Report return to the ordering physician is approximately five working days following disconnection, but this may vary depending on the reading physician. Same day report return for urgent cases is available upon request. Verbal and preliminary reports can be obtained through the Cardiac Monitoring department at 604-507-5106 or 1-800-565-1441.
