49 Cardiac pacing in first degree AV-block Figure 5. Hemodynamic effect of improving atrioventricular (AV)-coupling in patients. ( A ) Left ven- tricular (LV) pressure ( Top row ), flow ( Second row ) and ECG ( Lowest row ), as measured in a repre- sentative patient. Diastolic mitral regurgitation (MR) is presented in yellow. Absolute changes in ( B ) diastolic mitral forward flow and ( C ) diastolic MR fraction as compared to baseline (AAI) in the entire cohort. Mean±SD are presented. * indicates p<0.05 as compared to baseline. 3
