This study compared cardiac output assessed by a noninvasive CO2 rebreathing method at identical submaximal exercise and heart rate response in patients undergoing DDD or VVI pacing. Our results did not show any hemodynamic superiority of AV synchronous pacing.
本研究比较了采用无创二氧化碳重吸入法评估的、处于相同次最大运动量时的心输出量,以及接受DDD或VVI起搏的患者的心率反应。我们的结果未显示房室同步起搏在血液动力学方面有任何优势。
