正常人头胸导联和常规导联右胸异常Q波的比较

Comparisons of Right Precordial ECG Q Waves Recorded by Head-chest Leads and Routine Leads in Healthy Adults

目的:比较常规导联心电图及头胸导联心电图所记录的正常人右胸导联Q波的特征。材料与方法:采用导联心电图机及头胸导联心电图机分别检查50个正常成人(30名男性,20名女性)的右胸心电图,记录Q波出现的频率及幅度。结果:头胸导联所记录到的Q波数及Q波幅度均显著低于常规导联心电图。结论:正常人头胸导联心电图较常规心电图较少出现右胸假性异常Q波。

Objective: To study the difference of ECG abnormal right precordial Q waves recorded by Head-Chest leads ECG and Routine leads ECG in healthy adults. Methods: 50 healthy young adults (age 18～25, 30 males, 20 females) were enrolled for the study, both Head-Chest leads and Rountine leads ECGs were recorded in right chest leads of all individuals, then Q waves amplitude and numbers of Q waves in each leads. Results: Q wave amplitude and Q wave numbers recorded in Head-Chest leads were lower than those recorded by Routine lead ECG. Conclusion: Head-Chest leads ECG is a useful tool in discriminating the pseudo Q wave in right chest leads.
