Proper 12-Lead ECG Electrode Placement
Key Points A diagnostic 12‑lead ECG is only as good as your electrode placement. Misplacement can mimic MI, BBB, or poor R‑wave progression and trigger unnecessary workups. A standard 12‑lead…
Avoiding Misdiagnosis Through Proper Lead Placement
A 40-year-old man with no known medical problems presents with concerns about his cardiac health after a friend recently had an MI. He has no symptoms of acute coronary syndrome…
