dc.description.abstract | BACKGROUND: Prolongation of the corrected QT (QTc) interval on 12-lead electrocardiogram is related to total mortality and sudden cardiac death. The value of the paced QTc interval in predicting mortality has not been investigated. OBJECTIVE: To evaluate the relationship between the paced QTc interval and mortality. METHODS: Of 1440 patients who underwent pacemaker implantation from January 1990 to March 2010, 766 had a recorded intrinsic and ventricular paced rhythm and were included in this study. The intrinsic and paced QTc intervals were measured on 12-lead electrocardiogram before and 1-month after implantation. RESULTS: During a mean follow-up period of 7 ± 5 years, 189 (24.4%) patients died, of which 63 (8.1%) were cardiac deaths. Compared with patients in the first tertile of the paced QTc interval (<484 ms), patients in the third tertile (>511 ms) were significantly more likely to die (19% vs 29%; P < .05). A comparison of the third and first tertiles of the QTc interval showed that a prolonged paced QTc interval was a significant independent predictor of all-cause mortality (adjusted hazard ratio 2.08; 95% confidence interval 1.44-3.01; P < .001) and cardiac mortality (adjusted hazard ratio 2.53; 95% confidence interval 1.29-4.95; P = .007) and a better predictor than was a prolonged intrinsic QTc interval. When treated as a continuous variable, a prolonged paced QTc interval predicted increased total mortality and cardiac mortality. CONCLUSION: The paced QTc interval appears to be a more useful marker in predicting bad prognosis than does the intrinsic QTc interval in patients with indications for a permanent pacemaker. | - |
