Real-time heart monitoring, made easy.

What’s the Difference Between Holter and MCT?
While both Holter and MCT heart monitors track your heart’s electrical activity, they do it in different ways:

• Holter monitors record continuously, usually for 24–48 hours. They’re great for catching frequent symptoms.
• MCT’s (Mobile Cardiac Telemetry Monitors) are worn longer—often up to 30 days—but only record during specific moments, either when you press a button or when the device detects something unusual on its own.

Both devices are easy to wear, non-invasive, and give your provider helpful data to better understand your symptoms.

Why You Might Need One
If you’re experiencing symptoms like palpitations, fainting, dizziness, or irregular heartbeats—but your in-office ECG looks normal—Holter or MCT Monitors may help catch the problem while you’re going about your day.

This kind of monitoring can detect things like:

• Abnormally fast or slow heartbeats
• Skipped beats or fluttering sensations
• Episodes that only occur occasionally
• These tools are especially useful when symptoms are unpredictable.

What to Expect While Wearing the Monitor

• Monitors are worn continuously. They attach to your chest with small electrodes and connect to a portable recording device. Just go about your routine—minus swimming or showering—and avoid heavy sweating if possible.

You may be asked to keep a brief journal of symptoms and activities. This helps correlate what you feel with what the monitor records.

Is It Safe?
Yes—both types of monitors are completely safe. There’s no electricity being sent into your body, and most people only experience mild skin irritation from the adhesive patches.

After the Monitoring Period
Once the monitoring is complete, your provider will review the recordings. In many cases, this helps confirm or rule out a diagnosis. You may be asked to come in for further testing, like a stress test or echocardiogram, depending on what the data shows.
