[COMPLETE ATRIOVENTRICULAR BLOCK DUE TO PULMONARY EMBOLISM]

Pulmonary embolism, a common and potentially fatal clinical condition, occurs when a blood thrombus becomes lodged in the pulmonary vasculature and creates an acute increment in the pulmonary vascular resistance, which, in turn, creates a right ventricular strain. Among the more familiar electrocardiographic manifestations in acute pulmonary embolism is sinus tachycardia, right bundle branch block and ST-T abnormalities in the right precordium leads. Complete heart block or any type of bradycardia is uncommon. In our case report we present an 81 years old woman who was admitted to our institution with acute pulmonary embolism and complete atrioventricular block, which later resolved with appropriate anticoagulation therapy.
