ECG Lead Misplacement
Key Points Lead misplacement is common and can mimic ischemia, MI, conduction blocks, and arrhythmias. Always verify placement when ECG and clinical picture do not match. V1 and V2 placed…
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…
