Hypertrophied myocardium is prone to proarrhythmic toxicity and development of the torsade de pointes type of ventricular tachycardia. 肥厚心肌对于抗心律失常药物的致心律失常毒性非常敏感，容易发生尖端扭转型室速。
Proarrhythmic risk is unpredictable;therefore, inpatient loading can lead to a false sense of security regarding future arrhythmic events. 由于心律不齐的危险是不可预知的，住院患者在用药期间可能产生关于日后心律失常事故的安全错误假象。
