Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents for evaluation of Long QT Syndrome (LQTS). History significant for [syncope/seizure/palpitations/family history of sudden cardiac death]. Current symptoms include [dizziness/presyncope/chest discomfort] triggered by [physical exertion/emotional stress/auditory stimuli/sleep]. Review of systems negative for recent viral illness or electrolyte disturbances. Current medications reviewed for QT-prolonging potential.
Clinical Examination Findings
Cardiovascular exam: Regular rate and rhythm, S1/S2 audible, no murmurs, rubs, or gallops. Peripheral pulses symmetric and full. No signs of congestive heart failure. Neurological exam: Alert and oriented x3, no focal deficits. Baseline ECG shows corrected QT interval (QTc) of [X] ms. Telemetry monitoring reveals [normal sinus rhythm/ventricular ectopy/T-wave alternans].
Treatment Protocol
Initiate [Beta-blocker therapy: Nadolol/Propranolol] at [dose] to suppress sympathetic triggers. Advise strict avoidance of QT-prolonging medications (refer to CredibleMeds). Consider ICD implantation for high-risk patients or those with recurrent syncope despite medical therapy. Lifestyle modification: Avoid competitive sports and intense physical exertion. Electrolyte optimization (potassium/magnesium) as indicated.
