Table 2.

The incidence of three kinds of f-QRS complexes in all subjects and different degrees of myocardial fibrosis subgroups.

f-QRS pattern	All patients	LGE% <35%	LGE%>35%	P value*

^*p according to the exact-Fisher test.

^#All fragmented QRS complexes were wide f-QRS with a QRS time > 120 ms in this study. Data are numbers of patients, and data in parentheses are percentages.

f-QRS, fragmented QRS; LGE, late gadolinium enhancement.
