In Review: Lead Placement
Accurate lead placement is invaluable, and makes a significant impact on appropriate care trajectory, or misdiagnosis with unnecessary utilization of resources. A common finding associated with V1 / V2 malposition is P wave inversion, and rSr’ QRS with T wave inversion -- potentially leading clinicians to suspect Brugada pattern, for example, when no such entity exists. Another spurious finding is a QS pattern that mimics Anterior MI, and in the acute setting this may elicit compulsory urge to pursue invasive coronary intervention that is entirely unwarranted.
