What is it indicated for?

The NowCardio™ System is an ambulatory cardiac monitoring system prescribed by a physician or other qualified

healthcare professional for out-patient individuals with known non-lethal arrhythmias such as:

• Atrial Fibrillation

• Bradycardia

• Tachycardia

• Pause

It continuously monitors, records, and stores electrocardiographic (ECG) data. If equipped with a transmitter, the

NowCardio™ will also periodically transmit ECG Cardiac Event to a remote computer server. Both recorded and

transmitted ECG data are available to HealthCare Providers for analysis and reporting.

NowCardio™ is intended to be used with adult patients 22 years and older, but not designed for pediatric patients.

Indications for use as stated in the FDA summary.
