本文报告1例多发性大动脉炎的女性患者,15岁。其心电图特征为左室肥厚、QRS波电压极度增高,超过国内吴迺理报导的最高1例(11.0mV)近2.0mV[中华心血管病杂志1985;13(4):265。],是女性左室肥厚诊断标准的3.7倍,RⅠ+SⅢ达左室肥厚诊断标准的2倍,V_2导联QRS波总幅度达10.0mV,V_3导联QRS总幅度达10.6mV,实属罕见。其原因:1、本例轻度贫血使血液传导性增加,从而使体表电势增大;2、肺部瘀血,传导性增加;3、身体消瘦、肌肉萎缩,造成体表电势极度增高;4、心脏极度扩大,靠近前、侧壁造成极高电压;5、上肢血供高于下肢,肢导电压差异较大。
This article reports 1 female polyarteronitis female patient, 15 years old. The ECG is characterized by left ventricular hypertrophy, QRS wave voltage is extremely high, exceeding the highest reported in China 1 case (11.0mV) of nearly 2.0mV [Chinese Journal of Cardiovascular Diseases 1985; 13 (4): 265. ] Is 3.7 times the diagnostic criteria for left ventricular hypertrophy in women, R Ⅰ + S Ⅲ 2 times the diagnostic criteria of left ventricular hypertrophy, V 2 leads QRS amplitude of the total 10.0mV, V_3 lead QRS total amplitude of 10.6mV, it is rare . The reason: 1, this case of mild anemia increased blood conductivity, so that the body surface potential increases; 2, lung stasis, increased conductivity; 3, the body weight loss, muscle atrophy, resulting in extremely high body surface potentials; 4, the heart is extremely enlarged, near the front, side walls cause very high voltage; 5, upper limb blood supply is higher than the lower limbs, limb lead voltage differences vary greatly.
