Background: Syncope is usually a benign event that affects up to 50% of people over a lifetime, needing no extensive examination. The challenge is to diagnose the few with underlying life-threatening disease in need of immediate medical attention. Guidelines are clear, but unfortunately, clinical practice does not always follow recommendations, as illustrated by this case report.
Case presentation: A diabetic, hypertensive male in his eighties had a myocardial infarction in his medical history. He presented to his GP with recurrent syncopal episodes that had occurred while erect and in motion. Physical examination was found to be normal for his age, and he was referred to a cardiologist and seen three months later. An ECG showed sinus rhythm and a previous inferior wall myocardial infarction. A 24-hour ECG recorder was fitted, and a consultation was scheduled for the next day. At home the patient died. The ECG recording revealed sinus rhythm with increasing depression of the ST segment, followed by rapidly conducted atrial fibrillation, and then rapid ventricular tachycardia followed by terminal ventricular fibrillation.
Interpretation: A patient with a history where there is suspicion of cardiac syncope should be immediately and intensively examined when presenting to the healthcare services.
