  1. Discriminatory power of tested parameters. These are listed grouped according to their demographic, anatomical or electrical nature. Some combined parameters were pre-specified and these are listed separate from other additional parameters. Key: BMI = body mass index; LA = left atrial diameter; DACL = dominating atrial cycle length; V1 = V1 lead; Oes = oesophageal lead; SR = sinus rhythm; AF = atrial fibrillation. Fischer exact test used to calculate p-values marked '*'. MannWhitney test used for all others.
