## Indications for use
The CardioNet Ambulatory ECG Monitor with Arrhythmia Detection intended use is for: 1. Patients who have a demonstrated need for cardiac monitoring. These may include but are not limited to patients who require monitoring for: a) non-life threatening arrhythmias such as supraventricular tachycardias (e.g. atrial fibrillation, atrial flutter, PACs, PSVT) and ventricular ectopy; b) evaluation of bradyarrhythmias and intermittent bundle branch block, including after cardiovascular surgery and myocardial infarction; and c) arrhythmias associated with co-morbid conditions such as hyperthyroidism or chronic lung disease 2. Patients with symptoms that may be due to cardiac arrhythmias. These may include but are not limited to symptoms such as: a) dizziness or lightheadedness; b) syncope of unknown etiology in which arrhythmias are suspected or need to be excluded; and c) dyspnea (shortness of breath). 3. Patients with palpitations with or without known arrhythmias to obtain correlation of rhythm with symptoms 4. Patients who require outpatient monitoring of antiarrhythmic therapy: a) monitoring of therapeutic and potential proarrhythmic effects of membrane active drugs b) monitoring of effect of drugs to control ventricular rate in various atrial arrhythmias (e.g. atrial fibrillation) 5. Patients recovering from cardiac surgery who are indicated for outpatient arrhythmia monitoring. 6. Patients with diagnosed sleep disordered breathing including sleep apnea (obstructive, central) to evaluate possible nocturnal arrhythmias 7. Patients requiring arrhythmia evaluation of etiology of stroke or transient cerebral ischenmia, possibly secondary to atrial fibrillation or atrial flutter 8. Patients requiring measurement, analysis and reporting of the OT interval, excluding patients with a documented history of sustained atrial fibrillation or atrial flutter.
