Case ReportsRecurrent syncope induced by left ventricular outflow tract obstruction: demonstration in a patient with hypertrophic obstructive cardiomyopathy.
A 70-year-old man presented with repeated syncope induced by left ventricular outflow tract obstruction. He was referred to us because of repeated syncope with convulsion at rest. During syncope, electrocardiography showed marked ST segment depression with negative T waves in leads I, II, aVL, aVF and V2-V5 but no arrhythmias. ⋯ During each episode, systemic blood pressure rose spontaneously with the recovery of consciousness over several minutes. He received temporary atrioventricular sequential pacing and underwent successful mitral valve replacement. Four years later, he was doing well.
