Pulmonary embolism is frequently overlooked but may be fatal. Hence, appropriate diagnosis heavily relies on clinical suspicion. Although most ECG features of pulmonary embolism lack specificity and sensitivity, especially when prior cardiopulmonary disease is present, certain ECG findings may heighten the initial clinical suspicion. This is illustrated in the following report on a case of proven pulmonary embolism complicated with cardiac arrest and prolonged shock. The electrocardiographic presentation was suggestive of an extensive acute myocardial infarction, a pattern which to our knowledge never has been reported on. However, many elements of it pointed to the diagnosis of pulmonary embolism. The multifactorial origin of the ECG findings is discussed.
