Background: We evaluated the associations among the well-known atrial fibrillation (AF) predictors including P-wave dispersion (PWD), intra-and inter-atrial electromechanical dyssynchrony (EMD), left atrial (LA) phasic functions, and plasma N-terminal prohormone of B-type natriuretic peptide (NT-proBNP) levels, in patients with hypertrophic cardiomyopathy (HCM p = 0.001), p = 0.03), p = 0.006), but not, however, to LAAEFr (p = 0.4). The plasma NT-proBNP levels of patients were not correlated with either (Cardiol J 2015; 22, 1: 94-100)
