[Cardioversion of amiodarone-insensitive atrial fibrillation by bepridil in heart failure: two case reports].
Two patients presented with atrial fibrillation which was refractory to amiodarone but successfully treated with bepridil. A 76-year-old man with ischemic cardiomyopathy, non-sustained ventricular tachycardia (NSVT) and atrial fibrillation received amiodarone for NSVT, which disappeared but atrial fibrillation was sustained. A month after receiving amiodarone, interstitial pneumonia occurred. Interstitial pneumonia was improved after amiodarone was discontinued, but NSVT occurred again. He received bepridil, when NSVT and atrial fibrillation disappeared. An 83-year-old man with dilated cardiomyopathy, NSVT, and atrial fibrillation received amiodarone for NSVT, which disappeared but atrial fibrillation was sustained. Five months after receiving amiodarone, interstitial pneumonia occurred. Interstitial pneumonia was improved after amiodarone was discontinued, but NSVT occurred again. He received bepridil, when NSVT and atrial fibrillation disappeared.
