Syllabus Breakdown (The 4 Domains)
The exam is heavily weighted towards the practical aspect of acquiring the EKG. Make sure you master lead placement and troubleshooting.
Domain 1: Safety & Compliance (32%)
- Infection Control & Standard Precautions
- HIPAA & Patient Privacy
- Patient Communication & Consent
- Vital Signs & Patient History
Domain 2: EKG Acquisition (44%)
- Patient Prep: Skin cleaning, shaving.
- Lead Placement: 12-lead (V1-V6), limb leads.
- Modifications: Amputees, pediatric, dextrocardia.
- Troubleshooting: Artifacts (somatic tremor, wandering baseline).
Domain 3: EKG Interpretation (24%)
- Anatomy: Conduction system (SA/AV node).
- Measurements: HR calculation, intervals (PR, QRS, QT).
- Rhythms: Sinus, Atrial, Ventricular, Blocks.
- Ischemia/Infarction: ST elevation/depression.
Domain 4: Stress & Ambulatory (10%)
- Stress Testing: Bruce protocol, termination criteria.
- Holter Monitoring: Patient diary, lead placement.
- Telemetry: Continuous monitoring basics.
Critical Skills You Must Master
- 12-Lead Placement: Memorize the exact location for V1 through V6. This is tested heavily.
- Artifact Troubleshooting: Know the difference between a wandering baseline (loose lead) and somatic tremor (patient movement).
- Arrhythmia Recognition: Be able to identify life-threatening rhythms like V-Fib, V-Tach, and Asystole instantly.
- Calculation Methods: Know the 1500 method (precise) and the 6-second method (irregular rhythms) for calculating heart rate.
