To evaluate the time course of recovery atrial mechanical function after pharmacological cardioversion chronic fibrillation to sinus rhythm.21 patients (12 male, 9 female, aged 37-77 years) with (< 6 months) were followed up by serial transmitral pulsed Doppler echocardiography. Echocardiographic studies performed within first 24 hours and on day 8, 15, 30 cardioversion.There was a significant increase (mean (SD)) in peak A-wave velocity (from 0.35 (0.10) 1 0.50 (1.73) thereafter gradual 0.61 (0.14) m/s 30). Similarly, integrated late velocities increased from 4.50 (1.46) 5.61 8 5.97 (1.47) cm/s2 30. The contribution total flow significantly 26 (7)% immediately conversion rhythm 34 30, indicating haemodynamic benefit restoration rhythm. Left diameter decreased but not significantly, 4.11 (0.37) 3.98 (0.34) cm (P < 0.005).These results suggest that is slow gradual, as it electrical DC This may have important implications for determining how long treatment anticoagulants antiarrhythmic agents needs continue individual patients. It will also influence clinical assessment restoring fibrillation.
