After more than 300 defibrillation shocks, patient still alive 12 years later refractory torsade de pointes due to polypharmacy and persistent vomiting

Acquired torsade de pointes ventricular tachycardia (tdp) is a rare but serious lifethreatening arrhythmia caused by an array of cardiac and non-cardiac drugs. it is often refractory to pharmacological therapy and may result in death or require frequent defibrillations. in our casestudy a young female patient with no underlying heart disease developed very frequent sustained tdp requiring frequent defibrillations without which she would have certainly died. the ventricular arrhythmia in this patient was of multifactorial origin – cisapride, drug–drug interaction and persistent vomiting resulting in electrolyte disturbance and malnutrition. the patient survived after more than 300 defibrillation shocks over a period of 5 days and she is still alive 12 years later.
