Holter Monitor Complications

The Holter monitor is a noninvasive method of assessing the heart's function. Risks associated with the Holter monitor are rare.

Prolonged application of the adhesive electrode patches may cause tissue breakdown or skin irritation at the application site.

There may be other risks depending upon your specific medical condition. Be sure to discuss any concerns with your physician prior to wearing the monitor.

Certain factors or conditions may interfere with or affect the results of the Holter monitor reading. These include, but are not limited to, the following:

• Close proximity to magnets, metal detectors, high-voltage electrical wires, and electrical appliances such as shavers, toothbrushes, and hair dryers
• Smoking, certain medications
• Excessive perspiration, which may cause the leads to loosen or detach
