Digital ECG Management System for the Heart Institute

One platform that joins SLMC's GE ECG and Stress Lab machines, OCIS, EHUB and Philips ISCV, so every ECG moves from order to signed report without being typed twice.

Today

  1. Order placed in OCIS
  2. Patient details typed into the machine
  3. ECG printed on paper
  4. Tracing carried to the cardiologist
  5. Interpretation written, then encoded
  6. Report uploaded to EHUB by hand

Three points where data is re-entered and errors can happen.

With the new system

  1. Order flows from OCIS automatically
  2. Machine receives the patient from the worklist
  3. Tracing arrives digitally, AI flags urgent patterns
  4. Cardiologist reviews and signs on screen or phone
  5. Report returns to OCIS and EHUB in seconds

Zero re-entry points. Every step logged.

All patient, physician and record data shown is fictional sample data. Use the left and right arrow keys to move between screens.

Demonstration flow: one STAT chest pain patient

  1. Secure sign-inSLMC Active Directory, MFA, lockout after 3 attempts
  2. ECG worklistOrders arrive from OCIS by HL7, including a live test
  3. Machines and worklist deliveryGE MAC and CASE units, worklist under 3 seconds
  4. Cardiologist review12-lead viewer, measure, compare, AI flag, on-call phone
  5. Signed report back to OCIS and EHUBDepartment templates, e-signature, HL7 result
  6. Patient ECG historyPrior ECGs and stress tests, side by side
  7. Heart Institute analyticsVolumes, turnaround, utilisation by department
  8. Security and auditRoles, PHI masking, live audit trail
  9. System health and continuity99.99% uptime, backups, RPO and RTO, environments
