The Electrocardiogram in Pulmonary Embolism

Abstract

Pulmonary embolism is a frequently clinically unrecognized entity [1]. Some studies suggest-that it might be the most common cause of death among hospitalized patients, either as its major or sole cause, or as a complication of other diseases contributing to death [2, 3]. Fatal episodes of pulmonary embolism are usually preceded by minor episodes producing more or less definite symptoms to the patient [4]. Recognition of these minor nonfatal episodes is of great importance to start therapy to prevent further embolic phenomena and death [5]. The diagnosis of pulmonary embolism is primarily one that is based upon a high index of suspicion, on one hand, because of a clinical setting that makes the patient prone to pulmonary embolism, and on the other hand, because of suggestive symptoms and signs [4]. Once suspected, the confirmation of the diagnosis of pulmonary embolism should be made as soon as possible by using the available diagnostic tools.
