Ecg Synchronous [new] Download -

Feature Name: ECG Synchronous Download

1. Overview

ECG Synchronous Download allows users to download electrocardiogram (ECG) data simultaneously from multiple leads or channels, ensuring that all downloaded signals are perfectly aligned in time. This is critical for accurate multi-lead analysis, remote diagnosis, and data archiving.

Q: What is the typical storage requirement for a 24-hour synchronous ECG? A: For a single-channel Holter at 250 Hz, approximately 500 MB after compression. For a 12-lead at 500 Hz, approximately 3-5 GB per day. Plan your archive storage accordingly. Ecg Synchronous Download

Centralized Archiving: Software like InnoBase ECG Software or Cardio Perfect allows doctors to manage a unified database accessible by multiple users. Clock sync: ensure device and host clocks are

Practical considerations for correct synchronous download

  1. Clock sync: ensure device and host clocks are synchronized (NTP or GPS). When not possible, record device clock and measure drift to correct timestamps later.
  2. Include absolute start time and sampling frequency in file headers.
  3. Preserve sequence continuity—no gaps or overlaps. If gaps exist, annotate them explicitly.
  4. Transfer metadata (lead mapping, gain, filter settings). Without them, morphology and measurements may be invalid.
  5. Maintain lossless or well-documented lossy compression. If compression changes timing or sample indices, supply mapping.
  6. Secure transfer: encrypt data in transit (TLS) and at rest; authenticate devices to prevent mismatches.
  7. Error handling: checksum, CRC, or digital signatures to detect corruption; retry logic for interrupted transfers.
  8. Regulatory and privacy compliance: maintain audit trails and patient identifiers per applicable regulations.
  • Edge computing: Process and compress data at the bedside gateway.
  • Tiered storage: Live data on fast SSDs, archived data on lower-cost HDDs or cloud cold storage (e.g., AWS Glacier).
  • Retention policies: Typically 7 years for diagnostic ECGs (per medico-legal requirements).

This is distinct from Asynchronous Download, where data is sent in chunks as bandwidth allows, often resulting in variable delays or latency.
