In contrast, PQ interval ≥240 ms, QRS duration ≥120 ms, nutrition, or respiratory failure were not associated with the incidence of sudden death. The multivariable analysis revealed that a PQ interval ≥240 ms (HR, 2.79; 95% CI, 1.9-7.19, P less then 0.05) or QRS duration ≥120 ms (HR, 9.41; 95% CI, 2.62-33.77, P less then 0.01) were independent factors associated with a higher occurrence of cardiac events than those observed with a PQ interval less then 240 ms or QRS duration less then 120 ms; these cardiac conduction parameters were
