克山病病人的QRS环畸形及蚀缺与死亡有关因素的研究

Deformity or notch of ORS vector loop and death factors in patients with Keshan disease

对克山病病人的ＱＲＳ畸形及蚀缺与死亡有关因素进行了研究。结果显示：病人的ＱＲＳ环畸形愈严重及蚀缺的深度和范围愈大，病人短年限内死亡率愈高，ＱＲＳ环畸形及蚀缺的死亡病人女性明显高于男性，ＱＲＳ环畸形及蚀缺的病人发病年限愈长，短年限内死亡率愈高，ＱＲＳ环畸形及蚀缺的病人心功能愈差，短年限内死亡率愈高，但也有部分临床治愈、潜克、慢克病人的发病年限短、心功能正常的ＱＲＳ环畸形及蚀缺的病人在短年限内死亡的，因此，如果判定克山病病人是否在短年限内死亡，关键要观察病人的ＱＲＳ环畸形的程度及蚀缺的深度和范围。

The relationship between deformity or notch of QRS vector loop (DNQL) and death factors in patients with Keshan disease was investigated.The results were as follows:the more deformed the QRS loop is ,and the deeper or broader its deficit is ,the higher the short term mortality of patients is;the Longer the patients suffer from DNQL,or the worse their heart function is the higher their short term mortality is ;among the victims of DNQL,women are more than men.Although some cases of chronic or potential Keshan disease with a short course of disease and normal heart function have been cured clinically,they die of DNQL in a short period.So it is the extent and range of DNQL which determines the denth possibility of patients in a short period.
