Symptomatic Long QT Syndrome Coexisting with Asymptomatic Acetylcholine-induced Vasospasm
We herein report a rare case of long QT syndrome (LQTS) coexisting with acetylcholine (Ach)-induced vasospasm. A 31-year-old woman experienced cardiopulmonary arrest during running. LQTS was diagnosed by an electrocardiogram, and the coexistence of Ach-induced vasospam was determined by an Ach provo...

description | We herein report a rare case of long QT syndrome (LQTS) coexisting with acetylcholine (Ach)-induced vasospasm. A 31-year-old woman experienced cardiopulmonary arrest during running. LQTS was diagnosed by an electrocardiogram, and the coexistence of Ach-induced vasospam was determined by an Ach provocation test on coronary angiography. Although an implantable cardioverter defibrillator was placed, a beta-blocker was not prescribed for two reasons: first, the patient showed Ach-induced vasospasm alone with no symptoms and no ST change by Ach injection, and second, the use of beta-blockers alone in such patients carries a risk of vasospasm-induced ventricular fibrillation. |
