Prognostic value of non-sustained ventricular tachycardia and the potential role of amiodarone treatment in hypertrophic cardiomyopathy: assessment in an unselected non-referral based patient population

摘要

Conclusions-In an unselected patient population with HCM, isolated, non- repetitive bursts of NSVT were not associ ated with adverse prognosis and so this arrhythmia does not appear to justify chronic antiarrhythmic treatment. Amio- darone, administered in relatively low doses, did not carry an independent and additive risk for cardiac mortality. Amio- darone may have contributed to the absence of sudden cardiac death in pa- tient s believed to be at higher risk because of multiple repetitive NSVT.
