Final answer:
Zio XT and Zio AT are devices used for cardiac monitoring to assess the risk of cardiovascular events or abnormal heart rhythms.
Step-by-step explanation:
Zio XT and Zio AT are two devices used for cardiac monitoring. They are used to assess the risk of cardiovascular events or abnormal heart rhythms. These devices are worn by patients for an extended period, usually for a few days up to multiple weeks, to continuously record their heart's electrical activity.
The collected data is then analyzed to identify any abnormal heart rhythms, such as arrhythmias or atrial fibrillation, which can increase the risk of cardiovascular events, like heart attacks or strokes. Based on the analysis, healthcare professionals can stratify the patient's risk and determine appropriate treatment or further diagnostic tests.
For example, patients with a high-risk profile may be recommended for more invasive procedures, such as cardiac catheterization or electrophysiology studies, to assess their heart's function in more detail.
