7 ms, p = 0.001), septal mitral annulus (104 8 11 vs. 93 8 10 ms, p = 0.01) and tricuspid annulus (right ventricular PA; 71 8 9 vs. 64 8 7 ms, p = 0.05). Interatrial conduction time (lateral PA -right ventricular PA) was delayed in patients with scleroderma compared with controls (88 8 13 vs. 76 8 11 ms, p = 0.01). A positive correlation was detected between interatrial electromechanical delay (lateral PA -right ventricular PA) and P d (r = 0.5, p = 0.03). Conclusion: Atrial conduction
