Résumé

Justification: The diagnosis of posterior myocardial infarction is difficult with atypical clinical signs. The electrocardiographic with 12 leads is often normal. But, early detection is important for the outcomes of patients. Objective: To show the digestive and electrocardiography signs of posterior myocardial infarction. The cardiac enzymatic is necessary for the diagnostic. Observations: Two patients with posterior myocardial infarction. The first is a man who had history of heart angina, hypercholesterolemia. The ECG with 17 leads show a ST segment elevation. A high blood levels of cardiac enzymatic was seen. The second is a woman hospitalised for hyperthermia and agitation. Three days earlier, she had nausea, vomiting and pain abdominal. The ECG was normal. An elevation of cardiac enzymatic was seen two days after admission. Discussion: In front of myocardial infarction, an electrocardiogrphy normal and atypical clinical can give an error diagnostic. About the diagnosis of posterior myocardiac infarction, posterior leads and mesure of cardiac enzymatic are necessary. Coronarography and echocardiography aren't immediately accessible. Conclusion: All digestive syndrom and acute chirurgical abdominal may be accompaned by electrocardiography with 17 leads and dosage of cardiac enzymatic. Rubrique: Réanimation médicale
