ABSTRACT
In atrial fibrillation, cardiac performance is dependent on both preceding RR (RR-1) and prepreceding RR (RR-2) intervals. However, relative contributions were not well defined. Left ventricular outflow peak ejection velocity (Vpe) was measured by echocardiography from 21 patients. The relation between RR-1 and Vpe could be divided into two zones; steep slope in short RR-1 intervals ( 0.5 sec). RR-2 had a weak negative association with Vpe. The mean squared correlation coefficient (r2 ) between RR-2 and Vpe was 0.15 +/-0.13 and improved to 0.29 +/-0.21 (p<0.001), when coordinates with RR-1
