在我院安置心脏起搏器的随访病人中,共抽取了20例进行分级极量蹬车运动试验,其中男性12例,女性8例,年龄23～75(平均46)岁。心律失常类型:完全性或莫氏Ⅱ型房室传导阻滞15例;病窦综合征5例(其中慢—快综合征1例)。安装起搏器时间最短一个月,最长12年。使用XCQ—1型心功能运动试验器,女性以25W、50W、75W……递增负荷量;男性以50W、100W、150W……递增负荷量进行试验。每级负荷运动3分钟,运动的终点为力竭(表示极量运动),运动中持续心电监护。结果显示最大运动量为50W者3例、75W5例、100W8例、150W4例。年老运动耐量小;女性较男性运动耐量小;心功能差的运动耐量小;房室传导阻滞者比病窦综合征者运动耐量小,平日经常参加体
Among the follow-up patients with pacemakers in our hospital, a total of 20 patients were enrolled in the treadmill test, including 12 males and 8 females, ranging in age from 23 to 75 (average 46 years). Arrhythmia type: Completeness or Mohs Ⅱ type of atrioventricular block in 15 cases; sick sinus syndrome in 5 cases (including 1 case of slow - fast syndrome). Pacemaker installation time of at least one month, up to 12 years. Using the XCQ-1 cardiac function test machine, the women increased the load by 25W, 50W, 75W, ... ... and the men carried out the test by increasing the load by 50W, 100W, 150W. Each level of exercise for 3 minutes, the end of the exercise for exhaustion (that a lot of exercise), exercise continuous ECG. The results showed that the maximum amount of exercise 50W in 3 cases, 75W5 cases, 100W8 cases, 150W4 cases. Young and old exercise tolerance; women than men less exercise tolerance; poor heart function of exercise tolerance; atrioventricular block than those with sinus syndrome less exercise tolerance, usually participate in the body on weekdays
