MODULE ID: SVC-01

Cardiac Pre-Screening Wing

STATUS: ACTIVE

Not a diagnosis. Does not replace clinicians. Escalates on red flags.

01/12MODULE: PROBLEM SPACE

The Problem

Low-risk cardiac symptoms lead to excessive ECGs, echoes, referrals.

Defensive ordering of cardiac panels
Repeat ECGs for stable patients
Unnecessary echocardiogram referrals
IMPACT METRICS
Unnecessary ECGs

08/12MODULE: SAFETY

Safety Triggers & Escalation

IMMEDIATE ESCALATION
  • Chest pain with radiation
  • Syncope or near-syncope
  • Severe dyspnoea
  • Abnormal vitals (HR <40 or >150)
  • Hemodynamic instability
CAUTION FLAGS
  • Age >65 with new symptoms
  • Family history of sudden cardiac death
  • Known cardiac disease
  • Multiple risk factors
09/12MODULE: USE CASES

Real-World Applications

Primary Care Triage
USE CASE 1

Primary Care Triage

Screen low-risk chest discomfort before ordering ECGs

Reduces unnecessary cardiac workups by 50%
Emergency Department
USE CASE 2

Emergency Department

Rapid risk stratification for non-urgent cardiac complaints

Faster disposition, reduced ED boarding
Telemedicine
USE CASE 3

Telemedicine

Remote cardiac assessment using wearable data

Enables safe home monitoring protocols
Pre-Operative Screening
USE CASE 4

Pre-Operative Screening

Cardiac risk assessment before non-cardiac surgery

Avoids unnecessary pre-op cardiac consults
