WHAT IS AN ECG HOLTER MONITOR?
A Holter ECG Monitor is a small, portable device that continuously records your heart’s electrical activity for 24 hours or longer to detect irregularities that may not appear during a standard ECG. Modern Holter monitors are wireless, allowing you to move freely while your heart’s activity is recorded during your normal daily routine.
HOW IS A C3+ HOLTER MONITOR FITTED AND HOW DOES IT WORK?
A Holter monitor is fitted using small adhesive electrodes placed on your chest to continuously record your heart activity. The white backing is removed from each electrode before application. The bottom electrode is positioned below the breastbone, while the top electrode is placed carefully to avoid overlapping with the device or other electrodes. Once connected, the monitor starts automatically, confirmed by a brief beep and an intermittent, faint green light.
