Emotional stress as a cause of syncope and torsade de pointes in patients with long QT syndrome
Introduction. Long QT syndrome (LQTS) is a disorder of myocardial repolarization characterized by the prolongation of QT interval and high risk propensity of torsade de pointes (TdP) that can lead to syncope, cardiac arrest and sudden death. Episodes may be provoked by various stimuli de...

| description | Introduction. Long QT syndrome (LQTS) is a disorder of myocardial
repolarization characterized by the prolongation of QT interval and high risk
propensity of torsade de pointes (TdP) that can lead to syncope, cardiac
arrest and sudden death. Episodes may be provoked by various stimuli
depending on the type of the condition. Case report. A 25- year-old famele
patient was hospitalized due to syncope that occurred immediately after her
solo concert, first time in her life. The patient studied solo singing and
after intensive preparations the first solo concert was organized.
Electrocardiography (ECG) on admission registered frequent ventricular
premature beats (VES), followed by polymorphic ventricular tachycardia - TdP
that degenerated into ventricular fibrilation (VF). After immediate
cardioversion magnesium and beta-blockers were administered. TdP was
registered again several times preceded by VES. The corrected QT interval
(QTc) was 516 msec. For secondary prevention of sudden cardiac death, a
cardioverter defibrillator was implanted, and beta-blockers continued. After
a 1-year follow-up there were no recurrent episodes of TdP, and measured QTc
was reduced to 484 msec. Conclusion. Patients with syncope following
intensive emotional stress should be evaluated for malignant arrhythmias in
the context of LQTS. |
