Abstract

BACKGROUND AND HYPOTHESIS

Interatrial block (IAB: P-duration > 100 ms) is poorly recognized in hospital populations. In addition to reduced left atrial function and left atrial enlargement it predicts atrial fibrillation and other arrthymias. P-terminal force (Ptf): +/- biphasic P in lead V(1) > or = area of 1 small square on the electrocardiogram (ECG) grid also indicates left atrial abnormality, particularly left atrial enlargement. These 2 should be related. We determined the intercorrelation.

METHODS AND RESULTS

Two blinded observers evaluated 500 consecutive patients' ECGs for both Ptf and IAB utilizing all 12 leads for IAB and V(1) for Ptf. Measurement differences were resolved in a consensus conference. Among 482 usable ECGs, IAB and Ptf were strongly and significantly correlated (chi(2) = 68.041; P < or = .001).

CONCLUSION

IAB and Ptf are significantly and strongly correlated and one should be expected in the majority of cases when the other is recognized.

摘要

背景与假设

在医院人群中，房内阻滞（IAB：P波时限>100毫秒）的识别率较低。除了左心房功能降低和左心房扩大外，它还可预测心房颤动和其他心律失常。P波终末电势（Ptf）：心电图（ECG）V1导联中±双相P波≥1个小方格的面积也提示左心房异常，尤其是左心房扩大。这两者应该相关。我们确定了它们之间的相互关系。

方法与结果

两名不知情的观察者对500例连续患者的心电图进行评估，评估IAB时使用全部12导联，评估Ptf时使用V1导联。测量差异在共识会议上得到解决。在482份可用心电图中，IAB与Ptf呈强显著相关（χ2 = 68.041；P≤0.001）。

结论

IAB与Ptf显著强相关，在大多数情况下，当识别出其中一个时，另一个也会出现。
