Course Description:
The complete rhythm refresher, plus 12-lead basics for the ACS pathway.
This course includes everything in the Pre-course Refresher, plus a module on the 12-lead ECG. You'll learn where the leads go, how contiguous leads map to the heart's territories, and how to recognize ST elevation and reciprocal change. It also covers the common STEMI mimics to keep in mind and the time-critical actions when STEMI is suspected. The final rhythm check expands to 25 strips.
What you'll learn
- Modules 1–6: the systematic approach, sinus, atrial and junctional, ventricular and arrest rhythms, AV blocks, and putting it together for ACLS.
- Module 7, 12-lead basics for the ACS pathway:
- lead placement
- the inferior, anterior and lateral territories
- ST elevation and reciprocal change
- STEMI mimics such as LBBB, paced rhythms, early repolarization, pericarditis and LVH
- time-critical actionsCourse details
- Online and self-paced, about 2 hours
- 7 modules, 42 lessons and 8 interactive activities
- A graded quiz after every module and a 25-strip final rhythm check:
- 80% to pass, unlimited attempts, with explanations after each attempt
Best for: nurses, paramedics, physicians, and dentists who work with 12-leads, or anyone who wants the most complete preparation for ACLS.
