NH-301 Ultimate Holter Analysis

• NH-301 is Norav Medical’s ultimate Holter analysis solution, designed to work seamlessly with the full NR series of Holter recorders. The system delivers true 12-lead and 3-lead high-quality ambulatory ECG acquisition based on Norav Medical’s market-leading signal processing technology.
• NH-301 operates independently as a standalone application or integrates with the Norav ECG Management System (NEMS), offering a complete and intuitive analysis environment for recordings up to 14 days of continuous data acquisition. The platform is built for cardiology departments, outpatient clinics, and clinical research environments where diagnostic accuracy, workflow efficiency, and data integrity are non-negotiable.
• The latest version of NH-301 introduces significant advances in event management, physician review tools, activity-correlated analysis, and reporting – making it one of the most capable Holter analysis platforms available for the NR recorder family.

Clinical Analysis

• High-resolution ECG processing across full recording duration
• Arrhythmia detection and classification
• Atrial Fibrillation algorithm – accurate AF detection and analysis
• QT and Long QT analysis – measurement integrated in UI graphs and reports
• ST segment monitoring across the full recording period
• Heart Rate Variability (HRV) analysis with Mean Overall HR metrics
• Pacemaker spike detection and analysis
• Respiration rate trend monitoring
• Physical activity display via integrated accelerometer data – correlates cardiac events with patient movement and rest phases
• Lead flexibility: 12 / 7 / 5 / 3 Lead support

Extreme Events Management

• Automatic identification and flagging of the fastest, slowest, longest, and shortest cardiac events during analysis
• Manual event assignment – right-click menu enables users to assign extreme event flags to specific events during review
• Visual event indicators – dedicated icons in the top-right corner of event cells for instant recognition
• Quick navigation tool – one-click jump to any flagged extreme event from the events toolbar
• Single flag management – intelligent system allows only one event per category, automatically transferring flags when reassigning

Physician Review Tools

• Color-coded beat differentiation and relabeling
• Personalized event names and tagging – edit event numbers, rename, and organize events for an intuitive review experience
• Simplified Next/Previous navigation and uniform printing – move through events and print exactly as displayed
• Artifact beat exclusion – artifact beats excluded from event calculations for improved reliability
• Partial section exclusion for flexible analysis of complex recordings
• Automated Conclusion templates for streamlined physician reporting
• Physician digital signature support – assign and manage individual signatures per user, appearing across all reports after review or confirmation

Reporting & Output

• Comprehensive report generation including all extreme event variables (lowest, highest, longest, shortest cardiac events)
• Mean Overall HR metrics extended for in-depth HRV and event analysis
• Templates folder validation – automatic verification on first launch after installation
• Direct Excel export for tabular reports
• PDF report output with laser or ink print support
• Physical activity trend integrated in final report output

Integration & Connectivity

• HL7, DICOM, GDT interoperability
• Compatible with NEMS-A, NEMS-Q, and NEMS-Web
• Multi-site and multi-user network capabilities
• Multiple language support

• NH-301 provides a complete, intuitive true 12/3-lead Holter analysis environment, supporting recordings from 24 hours up to 336 hours (14 days) of uninterrupted data acquisition.
• Advanced algorithms deliver accurate detection and classification of arrhythmia, AF, QT/Long QT, ST changes, HRV, and pacemaker events – across the full recording duration.
• Accelerometer data from compatible NR recorders is displayed alongside ECG data throughout the recording, enabling activity-correlated clinical interpretation. Physicians can identify whether events occur during exertion, rest, or sleep – supporting clinical differentiation between activity-induced and spontaneous arrhythmia.
• The Extreme Events Management module automatically identifies and flags the critical events within each category, with visual indicators and direct navigation tools – so no clinically significant event is overlooked.
• Automated Conclusion templates reduce physician documentation time while maintaining report consistency across departments.
• Physician digital signature is embedded directly in report output, supporting compliance and paperless approval workflows.
• Comprehensive display and automated print functions throughout analysis.
• Remote analysis and data uploading for multi-site deployment.
• QT and Long QT analysis fully integrated in UI, graphs, and final reports.
• 24-hour to 336-hour recording support.
