Abstract: 探讨心房颤动(简称房颤)患者体表心电图QT间期的变化.入选81例房颤患者和71例对照者,测量Ⅰ导联和V2导联QT间期,根据Bazett公式计算QTc.结果:窦性心律时V2导联QT间期可测量性略高于Ⅰ导联,而房颤时相反.V2导联测得的QTc比Ⅰ导联长.房颤组与对照组比较,窦性心律时Ⅰ导联和V2导联的QTc两组间均无明显差异;房颤发作时Ⅰ导联QTc较对照组延长(429.01±43.08 ms vs 408.50±31.93 ms,P<0.05);V2导联QTc较对照组也延长(444.45±33.16 ms vs 414.82±25.57 ms,P<0.05).房颤组房颤发作时与窦性心律时的自身对照比较,V2导联的QTc也延长(448.63±31.59 ms vs 426.22±29.08 ms,P<0.05).结论:房颤患者在房颤发作时QTc延长,而房颤患者窦性心律时QTc与对照组无差异.
