Cardiac Monitoring

A cardiac monitor is a small device used to track your heart’s electrical activity. There are many types of monitors and they can be worn for 24 hours to 14 days. These monitors are designed to monitor your heart rhythm throughout your daily activities. Your doctor may monitor your heart activity with one of these monitors to check for electrical abnormalities in your heart and, if found, to determine the best course of treatment.

Holter Monitor

A Holter monitor is a battery-operated portable device that measures and records your heart’s activity (ECG) continuously for 24 to 48 hours or longer depending on the type of monitoring used. The device is the size of a small camera. It has wires with silver dollar-sized electrodes that attach to your skin. The Holter monitor and other devices that record your ECG as you go about your daily activities are called ambulatory

Long-Term Holter

Cardiac event monitoring is a long term diagnostic tool used by medical professionals to connect patient symptoms to cardiac events. Cardiac event monitoring is generally ordered by physicians when the symptoms are not captured in a 24 hour Holter monitor or when the clinician suspects the symptoms too transient to be captured in a 24 hour monitoring period.

King of Hearts Express (KOH)

The King of Hearts Express (KOH) is a patient activated monitor that is worn for 30 days. It is used to evaluate symptoms such as dizziness, palpitations, and chest pain. It captures EKG information before and after you experience a cardiac symptom.
