Orthostatic Hypotension: QTc Interval Prolongation during Head-Up Tilt

International Journal of Clinical Medicine 2024年第9期15卷 443-455页

作者： Gabriel Vanerio maria jose Arocena Department of Cardiology British Hospital Montevideo Montevideo Uruguay Electrophysiology Clinic CASMU IAMPP Montevideo Uruguay

Background: The QT interval shortens in response to sympathetic stimulation. Head-up tilt-table (HUT) testing is a straightforward way to achieve brisk sympathetic stimulation. There is not enough information about the response of the QT interval to HUT, particularly, in patients with orthostatic hypotension (OH). Objective: Analyse the response of the RR, QT and QTc intervals in patients with OH and reflex syncope (NM) during HUT and find differences between groups. Methods: We reviewed the electrocardiograms and compare the RR and QT/QTc intervals during 1) baseline;2) HUT plus hyperventilation;3) positive test. Results: We studied 137 patients, 62 control group (no syncope and negative HUT). On average, the RR HUT interval was shorter than the resting RR by −171 ± 110.4 ms in controls;−228.6 ± 119.4 ms (NM) and −194 ± (OH) (P Conclusion: Significant differences between the reflex group and the OH during a positive test, the QTc decreased in the NM group, but in the OH population increased. This observation has not been described. We hypothesize that QTc prolongation could reflect autonomic nervous system downregulation and could explain to a degree, the increased mortality in this group.

选自沃尔夫冈·阿玛多伊斯·莫扎特(Wolfgang Amadeus Mozart)的歌剧《后宫诱逃》(Die Entführung aus dem Serail)的咏叹调“Marten Aller Arten”,被认为是最具挑战性的女高音咏叹调之一。演唱这首咏叹调需要歌唱者具备较高的歌唱技术,包含歌唱中气息的灵活性、音与音之间的过渡和衔接、可长时间保持发声与音准的气息强度。此外,还需要歌唱者拥有宽广的音域和能够随时转换音高的能力。现今大众仍普遍认同的观点是,戏剧性的声音是沉重的、强烈的、甚至阴暗的,这与敏捷、灵活与明亮的声音几乎是对立的。通常情况下,敏捷、清晰的声音会更多地与闹剧或喜剧作品联系在一起,而沉重、强烈的声音则更多地与戏剧联系在一起。本文中,笔者尝试证明这两种音色可以同时存在于一个曲目中,由抒情花腔女高音扮演的康斯坦斯这一角色正好可以证明笔者的观点。本文提出了一些可供参考的观点,以帮助读者从不同的技术角度了解女高音如何处理声区转换,以支持其在主要音域中以饱满的嗓音演唱歌曲,使声音放开,并实现咏叹调“Marten Aller Arten”所要求的戏剧性。同时,本文以意大利美声学派的原则为基础,介绍了该咏叹调的技术方法——其重点集中于四个声区:胸声区、弱混声区、强混声区和头声区。本文比较了意大利美声学派的一些歌唱方法和关于声区的不同技术的概念。尽管这些概念仍会引起混淆,但这一新的视角有助于帮助人们理解女高音声区的结构,并将其更清晰地带入实践当中。了解了这四个音区的工作原理,女高音歌唱家就能更自如地去演绎这首咏叹调,并将嗓音发挥到极致,帮助歌唱家们更深入地了解自己的“乐器”,加强声音本身的柔韧性、肌肉和嗓音的调节能力,这些都是演唱咏叹调“Marten Aller Arten”所需要的。
