Clinical variables according to arrhythmia.

–brain natriuretic peptide; and total, total number of findings. LV identifies left ventricle; nsVT, non-sustained ventricular tachycardia; NT-proBNP, N-terminal pro
–Whitney test for continuous data and the Fisher's exact test for nominal and categorical data. Mann

– 脑钠肽（brain natriuretic peptide）；以及总计数、检查结果总数（total number of findings）。LV即左心室（left ventricle）；nsVT为非持续性室性心动过速（non-sustained ventricular tachycardia）；NT-proBNP为N末端前体脑钠肽原（原文截断为N-terminal pro）。
– 连续型资料采用曼-惠特尼检验（Mann-Whitney test），名义分类资料则采用Fisher确切概率法（Fisher's exact test）。
