Zio Patch Heart Rhythm Recording
The Zio patch is a small, lightweight heart monitor worn on your chest for up to 14 days, continuously recording your heart rhythm to detect irregular heartbeats that shorter monitors may miss.
A discreet wearable sensor records your heart rhythm continuously for up to 14 days, improving the chance of detecting intermittent palpitations and arrhythmias.
What to Expect
The Zio Patch recording is a service provided in the field of cardiology, designed to monitor the patient's heart activity over an extended period. During a face-to-face consultation, the patient will receive the Zio Patch, a small, lightweight device that adheres to the skin and records the heart's electrical activity continuously. This process typically lasts for up to 14 days, during which the patient is encouraged to maintain their normal daily activities.
The recorded data will help healthcare professionals assess the patient's heart rhythm and identify any irregularities that may indicate underlying cardiovascular issues. By analyzing the comprehensive data collected, the provider can make informed decisions regarding further diagnostic testing or treatment options, ultimately aiding in the timely management of the patient's cardiac health.

Frequently Asked Questions
What is a Zio Patch?
The Zio Patch is a small, lightweight, adhesive heart monitor worn on the chest. It continuously records your heart's electrical activity (ECG) for up to 14 days, providing far more data than a standard 24-hour Holter monitor.
How long do I wear the Zio Patch?
