左束支传导阻滞的诊断通常通过心电图(ECG)来确定,心电图上会显示出特定的波形变化。治疗左束支传导阻滞的方法取决于病因和患者的具体症状,可能包括药物治疗、心脏起搏器植入或在某些情况下进行心脏手术。 总结:lbbb指的是左束支传导阻滞,是一种心脏电信号传导异常,可能影响心脏功能,需通过心电图诊断并根据具体情况...
1岁雌性秋田犬 ECG记录如下:(50 mm/s; 5 mm/mV) (点击看大图) Q: 心电图结果有何异常?临床意义? A: AF+LBBB 分析: 1、主要节律是宽 QRS 波群(QRS 持续时间约 90 ms)和不规则(210 至 310 ms 之间的可变 R-R 间期)心动过速,平均心率为 220 bpm。没有清晰...
Numerous ECG criteria indicating possible acute onset of LBBB have been published during past decades. However, none of them have shown reasonable diagnostic power yet. Objectives: The aim of our study was to test the diagnostic value of 16 ECG criteria which have been proposed for the diagnosis...
In this general context it may be noted that prediction of imminent development of complete AV block among patients with apparently stable bifascicular block has proved difficult, even with electrophysiologic study.' As has been suggested previrously by Vera et al.,8 it is possible that ...

Finally, when QRS duration exceeded 160msec, almost all of the patients had LVEF less than 30%.Conclusion- LV systolic function could be estimated with an acceptable sensitivity by observing surface ECG in LBBB cases. This observation may lead to conceptual support for ...
Heart failure patients with left bundle branch block (LBBB) benefit from cardiac resynchronization therapy (CRT). We aimed to determine whether QRS morphology assessed by QRS complexity might identify clinical CRT non-responders. Methods Resting supine 12-lead ECG was obtained from Holter recordings pe...
