Lead Misplacement
Key Points Proper lead placement is critical to avoid misdiagnoses that can lead to unnecessary interventions and patient harm. Misplaced precordial leads (V1-V6) can mimic ischemia and cause false MI…
The Approach to Uncovering Hidden STEMI
A 92-year-old man presents to the emergency department with acute chest pain and diaphoresis. The following ECG is obtained:
ECG Basics and Fundamentals: limb lead reversal
A 82-year-old woman presents to the ED “not feeling well”. She reports malaise, mild dyspnea, but denies any pain. Vital signs are normal. The following ECG is obtained on arrival…
