Part I: Limb lead Reversals JF - International Journal of Medical Students JA - Int J Med Stud VL - 2 IS - 3 SE - Original Article DO - 10.5195/ijms.2014.95 UR - https://ijms.info/IJMS/article/view/95 SP - 92-98 AB - <p><strong>Background:</strong> Electrocardiography is a very useful diagnostic tool. However, errors in placement of ECG leads can create artifacts, mimic pathologies, and hinder proper ECG interpretation. This is the second of a two-part series discussing how to recognize and avoid these errors. <br><br><strong>Methods:</strong> 12-lead ECGs were recorded in a single male healthy subject in his mid 20s. Various precordial lead misplacements were compared to ECG recordings from correct lead placement. <br><br><strong>Results:</strong> Precordial misplacements caused classical changes in ECG patterns. Techniques of differentiating these ECG patterns from true pathological findings were described. <br><br><strong>Conclusion:</strong> As in Part I of this series, recognition and interpretation of common ECG placement errors is critical in providing optimal patient care.</p> ER -
