电心电图 (ECG) 的变化,包括延长的P波最大值和P分散,与冠状动脉慢流现象 (CSFP) 有显著的关联. 这些心电图发现可以作为在侵入性血管造影之前对CSFP的有价值的诊断指标.
科学领域:
- 心脏病学 心脏病学
- 诊断成像 诊断成像 诊断成像
- 临床电生理学 临床电生理学
背景情况:
- 冠状动脉慢流现象 (CSFP) 诊断目前仅依赖于心上冠状动脉血管学.
- 需要使用非侵入性诊断工具来识别CSFP.
研究的目的:
- 系统地审查和比较患有和没有CSFP的患者的心电图 (ECG) 发现.
- 为了确定CSFP诊断的潜在ECG标志物.
主要方法:
- 在MEDLINE,Scopus,Embase和Web of Science的系统文献搜索到2023年2月.
- 通过使用随机效应模型对32项涉及3937名患者的研究进行了元分析,其中包括2,069名CSFP患者.
- 计算各种心电图参数的平均差异和赔率比.
主要成果:
- 在CSFP患者中,P波最大值 (Pmax) 和P分散 (Pd) 显著增加.
- 在CSFP组中观察到QT波,未纠正的QTd和纠正的分散 (QTcd) 的持续时间延长.
- 在CSFP患者中注意到额头QRS-T角度和T-峰到T-终点 (Tp-e) 间隔的升高.
结论:
- 一些心电图参数,包括Pmax,Pd,QT,QTc,QTd,QTcd,Tp-e和正面QRS-T角度,在CSFP中发生显著变化.
- 这些心电图发现显示了CSFP的潜在非侵入性诊断指标的潜力,在冠状动脉血管学之前.

Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
