## Indications for use
The NH-301 Ambulatory ECG Analysis Software is intended for patients requiring ambulatory (Halter) monitoring from i to 168 hours. Such monitoring is most frequently used for the following indications: 1. Evaluation of symptoms suggesting arrfhythmia or myocardial ischemnia. 2. Evaluation of ECG documenting therapeutic interventions in individual patients or groups of patients. 3. Evaluation of patients for ST segment changes. 4. Evaluation of patient's response after resuming occupational or recreational activities, (e.g., after Mil. or cardiac surgery.) 5. Clinical and epidemiological research studies. 6. Norav Hotter Systems containing Heart Rate Variability (HRV) software have been tested to measure Heart Rate Variability within 4 ms tolerance. The clinical significance of Heart Rate Variability measures should be determined by a physician. 7. Evaluation of patients with pacemakers
