    Abstract:
    Hypokalemia, as an adverse consequence of severe alkalosis, can prolong QT interval and cause torsades de pointes. This report describes a rare case of central neurogenic hyperventilation as a result of brainstem infarct, presenting primarily with refractory ventricular tachyarrhythmia due to secondary hypokalemia.
