目的探讨碎片状QRS波对高血压左室肥厚的诊断价值。方法选取2003年1月～2010年12月在大同市第四人民医院心内科住院,并确诊为高血压的患者208例,其中11例(9例心电图表现为左、右束支传导阻滞,2例起搏心律)被排除。其余197例经超声心动图检查确诊为左室肥厚的94例,将此94例作为研究组,103例非左室肥厚者作为对照组。结果心电图碎片状QRS波诊断高血压左室肥厚,其敏感性高于左室肥厚的电压标准,特异性略低。结论碎片状QRS波在高血压左室肥厚患者中容易出现,与左室电压改变相比,十二导联心电图碎片状QRS波诊断左室肥厚有更高的敏感性。
Objective To investigate the diagnostic value of fragment QRS wave on left ventricular hypertrophy in patients with hypertension. Methods From January 2003 to December 2010 in Datong Fourth People ’s Hospital, Department of Cardiology, hospitalized and diagnosed as hypertension in 208 patients, of which 11 cases (9 cases of ECG showed left and right bundle branch block, 2 cases of pacemaker) were excluded. Ninety-seven patients with left ventricular hypertrophy were diagnosed by echocardiography in the other 197 patients. The 94 patients were included as study group and 103 non-LV hypertrophy patients as control group. Results ECG-chip QRS wave diagnosis of hypertension, left ventricular hypertrophy, its sensitivity is higher than the voltage standard of left ventricular hypertrophy, the specificity is slightly lower. Conclusions Fragmented QRS wave is more likely to occur in hypertensive patients with left ventricular hypertrophy. Compared with left ventricular voltage change, QRS wave of 12-lead electrocardiogram has higher sensitivity in diagnosing left ventricular hypertrophy.
