Ambulatory cardiac monitor (ZIO XT patch) on chest x-ray

Case contributed by Doralice Ferreira

Presentation

Past medical history of atrial fibrillation on metoprolol, presenting with chest pressure and palpitations.

Patient Data

Age: 45 years
Gender: Male

1. Low lung volumes. Mild to moderate bilateral peribronchial thickening.

2. No focal pneumonia, effusion or pneumothorax.

3. The heart and central pulmonary vascularity are normal and stable.

4. Unfolding of the ascending aorta. No acute displaced fracture.

5. ZIO XT patch (ambulatory cardiac monitor) is seen projecting over the left upper zone. No leads and wires are visualized on this exam.

Case Discussion

The FDA-cleared ZIO XT patch is a small, adhesive, water-resistant one lead ECG sensor capable of continuous 24-hour monitoring 1. The hydrogel electrodes provide clear ECG tracings and a button to capture symptomatic events. The ZIO XT patch is intended to replace the familiar but bulkier Holter monitor, which involves 5 to 7 leads connected to a central processing unit 2.

This case demonstrates the radiographic appearance of newer devices to aid diagnosis.
