本组采用WFB型四肢序贯式正压反搏装置治疗40例冠心病患者。经反搏后大多数患者心绞痛、胸痛消失或减轻,症状改善总有效率为87.5％,心电图总有效率62.5％。本组还观察反搏前后的Q—TQ间期及ptfV_1等变化。发现QT—C间期异常延长的6例在反搏后有4例缩短至时常;ptfV_1有异常负值增大的6例,反搏后缩小至正常的2例其ST—T也恢复正常。上述变化与心肌缺血的改善有关,有助于监测反搏和分析疗效。
This group of WFB type limbs sequential positive pressure counterpulsation device treatment of 40 patients with coronary heart disease. After the counterpulsation most patients with angina pectoris, chest pain disappeared or reduced, the total effective rate of symptom improvement was 87.5%, the total effective rate of ECG 62.5%. This group also observed before and after counterpulsation Q-TQ interval and ptfV_1 and other changes. Six cases of abnormal prolongation of QT-C interval were found to be shortened to normal after the counterpulsation. Six cases of abnormal increase of ptfV_1 were found, and ST-T returned to normal after the counterpulsation was reduced to the normal two cases. These changes related to the improvement of myocardial ischemia, help to monitor the counterpulsation and analysis of curative effect.
