Table 3.

Degree and significance, in descending order, of correlations between λ_d of measured right atrial locations with mean left atrial λ_d

λd values of measured RA locations	Correlation with mean LA λd
CTI	r2 = 0.76, P < .001
Septal RA	r2 = 0.58, P < .001
RAA	r2 = 0.52, P < .001
SVC-RA junction	r2 = 0.49, P < .001
Lateral RA	r2 = 0.45, P < .001
Posterior RA	r2 = 0.12, P = .037

CTI = cavotricuspid isthmus; LA = left atrial; RA = right atrial; RAA = right atrial appendage; SVC = superior vena cava.
