Table 4. Correlation of RVPSS, TAPSE, RVFAC and LVGLS with occurrence of RV- involvement in TC using Kendall-Tau-b correlation coefficient.

	Kendall-Tau-b correlation coefficient	p-value
RVPSS	0.490	0.004
RVFAC	−0.499	0.003
TAPSE	−0.379	0.025
LVGLS	0.329	0.048

RV: right ventricular, TC: Takotsubo cardiomyopathy, RVPSS: right ventricular peak systolic strain, RVFAC: right ventricular fractional area change, TAPSE: tricuspid annular plane systolic excursion, LVGLS: left ventricular global strain.
