Patients with atrial fibrillation (AF) referred for exercise rehabilitation exemplify the problem inherent in reliance on pulse rate to prescribe and monitor training intensity.
Exercise training was accomplished by specifying a training walking pace based on 60% to 80% of the peak oxygen intake (VO2max), as determined by the analysis of expired air (Horizon metabolic cart), and/or the ventilatory threshold (VT), together with a perceived exertion of 12 to 14 on the original Borg scale of perceived exertion.
At the end of 1 year, a significant training effect was demonstrated (VO2max average increase 15%, 14.8 +/- 3.6 mL/kg/min to 17.0 +/- 3.6 mL/kg/min, P < .02; VO2 at VT, average increase 14%, 11.2 +/- 2.2 to 12.8 +/- 2.6 mL/kg/min, P < .01; peak power output increase 21%, 92.5 +/- 29.3 Watts to 112 +/- 3.7 Watts, P < .05) in a group of 20 patients (13 men, 7 women) with chronic atrial fibrillation.
Patients with chronic atrial fibrillation can achieve significant functional gains from an exercise rehabilitation program.
被转介接受运动康复治疗的心房颤动(AF)患者体现了依赖脉搏率来规定和监测训练强度所固有的问题。
运动训练通过根据峰值摄氧量(VO2max)的60%至80%确定训练步行速度来完成,VO2max由呼出气体分析(地平线代谢仪)和/或通气阈值(VT)测定,同时在原始的伯格自觉用力量表上的自觉用力程度为12至14。
在1年结束时,一组20例慢性心房颤动患者(13例男性,7例女性)显示出显著的训练效果(VO2max平均增加15%,从14.8±3.6 mL/kg/min增至17.0±3.6 mL/kg/min,P<.02;VT时的VO2平均增加14%,从11.2±2.2增至12.8±2.6 mL/kg/min,P<.01;峰值功率输出增加21%,从92.5±29.3瓦增至112±3.7瓦,P<.05)。
慢性心房颤动患者可从运动康复计划中获得显著的功能改善。
