概括
导电系统节奏 (CSP) 可能导致心脏起器植入 (PMI) 后中度或严重的三腹吐 (TR). 虽然TR恶化没有显著差异,但CSP患者的中度/重度TR长期发病率较高.
科学领域:
- 心脏病学 心脏病学
- 心脏电生理学 心脏电生理学
- 心血管成像 - 心血管成像
背景情况:
- 三管吐 (TR) 是已知的心脏起器植入 (PMI) 的并发症.
- 导电系统节奏 (CSP) 是一种新的技术,旨在减少心室异步.
- CSP对TR发展的影响尚不清楚.
研究的目的:
- 调查CSP与PMI后TR的发展或恶化之间的关联.
- 为了比较接受CSP和传统PMI的患者的TR严重程度.
主要方法:
- 对110名接受PMI的患者进行了术前和术后的胸前心脏回声图 (TTE) 的回顾性分析.
- TR的严重程度被分级,TR的恶化被定义为至少增加一级.
- 患者根据他们是否接受CSP或常规节拍进行了分类.
主要成果:
- 总体而言,18.2%的患者出现TR恶化,6.4%的患者在PMI后出现中度或重度TR.
- 在CSP和非CSP组 (27.8%与16.3%,P=0.25) 之间没有观察到TR恶化频率的显著差异.
- 然而,在中期随访中,CSP组的中度或重度TR频率显著更高 (16.7%与4.3%,P=0.05).
结论:
- 虽然CSP可能不会显著增加TR恶化的总体发病率,但在中期内,它与中度或重度TR的更高频率有关.
- 需要进一步的研究,以了解CSP对三巴功能的机制和长期影响.

Assessment of the Cardiovascular System IV: Auscultation
152
Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
