The medilog® ADAPT™ algorithm is designed to provide highly accurate beat detection (99.9% accuracy). All recorded channels are analyzed and excessively noisy episodes are automatically excluded.

The key to effectiveness is due to:

  • Highest quality acquisition: 32,000 Hz sampling rate
  • Recording Rate 250 Hz
  • 3D motion detection to suppress artifacts
  • Noise Directory for a fast cleanup
  • Fast and Easy Template Editing


DARWIN2 is an analysis program for storage, analysis and diagnosis of medilogAR Holter recordings.

Also offers an intuitive workflow with a maximum flexibility with freely configurable reports and user-defined screen layout.

The DARWIN2 has an accurate beat classification. It’s Easy-to-use graphic interface allows users to distinguish, through a color code assigned, each type of arrhythmia, ventricular activity through QT and ST elevation or depression or the appearance of different events in time.

These automated features allow physicians to quickly report results, optimizing clinician time.


  • Archiving, editing, diagnostic and validation functions
  • On-screen measurements, editing of global measurement points and interpretation
  • Patient data editing
  • Selectable print formats
  • Patient and recording search function
  • PDF report generation
  • Role-based login
  • Assignment of recordings for analysis/editing by other users.


The DARWIN2 offers fully configurable reporting and analysis functions according to clinician requirements, defining standardized statements of interpretation and configuring different report templates for types of patients.

Basically the custom reports feature allows PDF report generation with the practice information and logo, which is then printed in the report header.

This module has:

  • Predefined reports
  • Personalized Report tool
  • Cover sheet templates
  • Summary templates

    With a few clicks, the physician retrieves, analyzes patient data and presents results in a customized report format.
