【摘要】：目的探讨应变、应变率成像(S/SRI)技术采用P波起点(P-onset)和R波顶点(R-peak)为起始点评价阵发性心房颤动(PAF)患者左心房(LA)功能的差异。方法分别以P-onset和R-peak为起始点分析52例PAF患者LA S/SR,比较两组LA S/SR并作一致性检验,分析两组LA S/SR与LA容积参数之间的相关性。结果以R-peak为起始点的心房泵血期和储血期的LA S均大于以P-onset为起始点的(均P0.05),但两组LA S/SR之间呈良好的相关性和一致性(均P0.05);两组LA S/SR与对应时相的LA容积参数之间也均表现出良好的相关性,且相关系数经比较并无显著性差异(均P0.05)。结论 P-onset和R-peak均可作为S/SRI技术的起始点评价PAF患者LA功能,两种方法测得的LA SR具有可比性,但LA S不具有可比性。
[Abstract]:Objective to study the strain, The function of left atrium in patients with paroxysmal atrial fibrillation (PAF) was evaluated with P wave starting point P-onsett and R wave vertex R-peak.Methods 52 patients with PAF were analyzed with P-onset and R-peak as starting points, respectively, and compared with each other in evaluating the function of left atrial lamina (LAA) in patients with paroxysmal atrial fibrillation (PAF). The two groups of LA SrSR were tested for consistency. Results the results showed that the LA S at the beginning point of R-peak was higher than that at P-onset (P 0.05), but there was a good correlation and agreement between LA S / SR of the two groups. There was also a good correlation between LA S / SR and LA volumetric parameters of the corresponding phase. Conclusion P-onset and R-peak can be used as the starting point for evaluating LA function in PAF patients. The LA SR measured by the two methods is comparable, but LA S is not comparable.
