We read with interest the article by Kürkciyan et al.1 Pulmonary embolism is a frequent and often underestimated underlying condition in patients admitted to emergency departments for cardiac arrest. In a previous study by our group2 on a consecutive series of 732 cases of sudden death referring to the emergency department in Ferrara, Italy, during an 11-year period pulmonary embolism was the second most common cause of death (n = 55; 7.5%) after myocardial infarction.
