aVR导联心电特征在急性心包炎诊断中的临床价值

Clinical Value of Lead aVR in the Diagnosis of Acute Pericarditis

【目的】探讨aVR导联在诊断急性心包炎中的临床价值。【方法】选择2007年7月至2011年7月本院临床确诊的急性心包炎患者41例，结合临床对心电图检查结果进行分析。【结果】41例急性心包炎患者中，35例（85．37％）有PR段偏移：aVR导联PR段抬高，余多数导联PR段压低。【结论】急性心包炎时aVR导联R段偏移或抬高为特征性表现，具有较高的诊断价值。

[Objective] To explore the clinical value of lead aVR in the diagnosis of acute pericarditis. [Methods] Forty one patients with acute pericarditis confirmed by clinical diagnosis were selected in our hospital from July 2007 to July 2011. Clinical manifestation and ECG results were analyzed. [Results] Of 41 patients with acute pericarditis, 35 patients（85.37 %） were PR segment deviation including the elevation of PR segment of lead aVR and the depression of PR segment of the most other leads. [Conclusion] Lead aVR in acute pericarditis has the characteristic performance, so it has high diagnostic value.
