摘　　要：目的探讨心电图V1导联P波终末电势(terminal force of P wave in lead V1,PTFv1)预测原发性高血压左心结构改变患者心律失常的价值。方法检测PTFv1负值增大原发性高血压左心室结构改变128例的动态心电图,并以PTFv1负值正常61例为对照。结果PTFv1负值增大组:①单纯左心房内径增大者房性心律失常(atrial arrhythmia,AA)检出率78．4％,高于PTFv1正常组(47．8％),差异有统计学意义(P<0．05);②单纯左心室肥厚者室性心律失常(ventricular arrhythmia,VA)检出率68．6％,高于PTFv1正常组(39．8％),差异有统计学意义(P<0．05);③左心房内径增大并左心室肥厚者AA检出率71．4％,高于PTFv1正常组(41．2％),差异有统计学意义(P<0．05)。结论原发性高血压左心结构改变患者的心电图PTFv1值可作为心律失常的危险因素。Objectives To study value of prediction of terminal force of P wave in lead v1 （PTFv1） on electrocardiogram （ECG） for arrhythimias in change of left cardiac structure in patients with primary hypertension. Methods 24-hour dynamic eletrocadiogram monitoring were recorded in 128 patients with abnomal PTFv1 （≤-0.04 mm·s） and 61 patients with nomal PTFv1 （≥-0.02 mm·s） in change of left cardiac structure of in patients with primary hypertension. Results （1） It was higher that incidence of atria arrhythimias（AA） detection in the left atrial enlargement（LAE） with abnomal PTFv1 than that with nomal PTFv1（78.4% vs 47.8% P〈0.05）. （2） It was higher that incidence of vetrucular arrhythimias（VA） detection in the left vetrucular hypertrophy（LVH） with abnomal PTFv1 than that with nomal PTFv1（68.6% vs 39.8% P〈 0.05）. （3） It was higher that incidence of AA detection in the LAE and LVH with abnomal PTFv1 than that with nomal PTFv1 （71.4% vs 41.2% P〈0.05）. Conclusions PTFv1 on ECG is a risk factor for arrhythimias in change of left cardiac structure of patients with primary hypertension.
