[Myocardial infarction in a man with Wolff-Parkinson-White syndrome].

A case of 52 years old male patient with antero-septal myocardial infarction in the course of type B Wolff-Parkinson-White syndrome has been described. Intravenous administration of 50 mg of ajmaline 2 hours after admission to hospital suppressed the electrocardiographic signs of preexcitation and disclosed previously imperceptible image of acute inferior myocardial infarction. Repeated intravenous ajmaline injection before discharging from the hospital enabled to specify the final localisation of the infarction (antero-septal and inferior), made possible the realization of ecg exercise test and ventricular late potentials analysis (no late potentials were detected). The clinical course of the disease was complicated by the left ventricular failure, which was brought in check without digitalis administration. The outpatient follow-up is carried out after the health resort treatment and the patient is in good conditions 6 months after his discharge from the hospital. There is no such a case found in the available literature.
