  2. Continuous, uninterrupted refers to the recording of ECG data. Zio AT Gateway transmissions may be impacted by a variety of factors. See Product Labeling for more information.
  3. Zio AT is contraindicated for critical care patients.
  4. Do not use Zio AT for patients with symptomatic episodes where variations in cardiac performance could result in immediate danger to the patient or when real-time or in-patient monitoring should be prescribed. Refer to the Zio AT labeling and Clinical Reference Manual for full contraindications.
  5. Zio AT does not require battery changes or charging. Zio AT has wear time transmission limits and is contraindicated for critical care patients. Refer to the Zio AT Clinical Reference Manual for additional information.  
  6. The monitor should not be submerged in water. During a bath, keep the monitor above water. Please refer to the device Instruction for Use or Clinical Reference Manual.
  7. Zio AT does not transmit ECG data while in airplane mode. Please refer to the device Clinical Reference Manual.
