Key result
Vasopressin induced acquired long QT with R on T ventricular ectopics in the setting of an intracerebral bleed, which reverted upon withdrawal of the medication.
Vasopressin can induce acquired long QT and ventricular arrhythmias in patients with intracerebral bleeding, which is reversible upon drug withdrawal.
Vasopressin may induce reversible acquired long QT with ectopics in intracerebral bleed; this case report leaves open need for systematic risk evaluation.
Long QT and ventricular tachyarrhythmias can occur due to a number of causes including dyselectrolytemia, drugs, and intracranial lesions, predominantly subarachnoid hemorrhage. Here the authors report a rare case of acquired long QT with R on T ventricular ectopics due to vasopressin in the setting of intracerebral bleed, which reverted on withdrawal of vasopressin.
