【Abstract】 Objective To investigate the relationship between QTds and JTds prolong and sudden death of old age diabetic patients.\ Methods\ The QTd and JTd of all the examinees were surveyed and compared (In the group of sudden death, the last ECG before death was surveyed). The longest QT or JT period minus the shortest QT or JT period was QTd or JTd. The results of the control group and diabetic group (sudden death group and survival group) were compared.\ Results\ The QTd, JTd of the old age diabetic patients was (78.24±27.68),(79.86±21.48) ms ,the control group was( 47.16±18.27),(46.32± 20.12 )ms, the difference was distinctive( t=6.63,7.23,P <0.001).The QTd, JTd of the old age diabetic patients in group of sudden death was (96.56±28.26),(98.78±30.42)ms, the survival group was (59.27±19.14),(60.47±21.52)ms.The difference was also distinctive ( t=5.93, 5.58,P <0.001).\ Conclusion\ The happening of sudden death in the old age diabetic patients increased with the prolongation of QTd, JTd. The increasing of QTd, JTd is a valuable index for predicting sudden death.更多还原
