EKG in Acute Pulmonary Embolism

Summary: This infographic explores the EKG findings associated with acute pulmonary embolism (PE). While EKG is not a diagnostic tool for PE due to low sensitivity and specificity, it can offer supporting evidence and aid in evaluating other causes of cardiopulmonary symptoms. The mechanisms for EKG changes in PE include increased adrenergic drive (e.g., sinus tachycardia), right atrial and ventricular dilation (e.g., right axis deviation, RBBB), and right ventricular ischemia or strain (e.g., S1-Q3-T3 pattern, T wave inversions in V1-V3).
