Intended Use

The Zio™ patch is a prescription only single patient use, continuous recording ECG monitor that can be worn for up to 14 days. It is indicated for use on patients who experience transient symptoms such as syncope, palpitations, shortness of breath, or chest pains.

Device Story

Zio™ patch is a single-patient-use, wearable, continuous ECG monitor. Device records cardiac electrical activity for up to 14 days. Worn by patients experiencing transient symptoms like syncope, palpitations, shortness of breath, or chest pain. After the monitoring period, the patch is returned for data analysis. Healthcare providers use the resulting ECG reports to evaluate cardiac rhythms and inform clinical decision-making regarding potential arrhythmias. The device facilitates long-term ambulatory monitoring, increasing the likelihood of capturing transient cardiac events compared to shorter-duration Holter monitors.

Clinical Evidence

No clinical data provided in the document; substantial equivalence is based on technological characteristics and intended use.
