摘　　要：目的；探讨老年冠心病患者及其亚组的Q－TC和J－TC离散度（Q－Tcd和J－Tcd）。方法：测量60例老年冠心病患者和60例无冠心病老年人心电图的R－R、Q－T、QRS和J－T（J－T=Q－T-QRS）间期，根据测量结果计算Q－Tcd和J－Tcd。结果：老年冠心病患者的平均Q-Tcd和J－Tcd均显著大于年龄相仿的无冠心病老年人（P＜0．001）。老年冠心病亚组中A组的平均Q－Tcd和J－Tcd显著小于B组（P＜0．02）和C组（P＜0．005、P＜0．01）。结论：本组结果提示Q－Tcd、J－Tcd可预示冠心病严重程度，作为预测冠心病预后的良好指标。Objective: The Q-Tc and J-Tc dispersion (Q-Tcd and J-Tcd)of the elderly patients with coronary heart disease (CHD) and their subgroups were studied. Methods: The R-R, Q-T, QRS and J-T (J-T=Q-T-QRS) interval of electrocardiogram in 60 elderly patients with CHD and 60 elders without CHD were measured. The Q-Tcd and J-Tcd were calculated according to the measured results. Results:The Q-Tcd and J-Tcd of the elderly patients with CHD were significantly greater than that of elders without CHD in the same age phase (P<0.001). In subgroups with CHD, the Q-Tcd and J-Tcd of A group was obviousIy smaller than that of B (P<0. 02) and C group (P<0.005 and P<0.01). Conclusion: The results suggest that Q-Tcd、J-Tcd may indicate the severity of CHD and regard as index for prognosis of Judgement.Author's address Navy Hangzhou Sanatorium, Hangzhou, 310002.
