概括
修改后的胸部导线 (MCLs) 为左捆分支区域节奏 (LBBAP) 监测提供了电生理学 (EP) 系统的可靠替代方案. 这项研究表明了强烈的相关性,使得MCL成为一个切实可行的选择,特别是在没有EP系统的地方.
科学领域:
- 心脏病学 心脏病学
- 电力生理学 电力生理学
- 医疗器械 医疗器械
背景情况:
- 左捆分支区域节奏 (LBBAP) 通常需要专门的电生理学 (EP) 系统,这些系统在许多导管实验室的可访问性有限.
- 修改的胸部导线 (MCL) 经常被用作标准V1和V6导线的替代品,但它们在LBBAP植入中的有效性尚未得到充分证实.
研究的目的:
- 评估在LBBAP植入过程中使用连接到节奏系统分析仪 (PSA) 的修改胸部导线 (MCL) 进行监测的可行性和可靠性.
- 为了将基于MCL的记录与传统EP系统的记录进行关键节奏参数的比较.
主要方法:
- 一项前性研究,涉及接受de novo输血永久心脏起器植入的患者,预计心室节拍负担很高.
- 基于ECG的EP系统记录与PSA的MCL记录进行了比较.
- 分析包括右捆分支块 (RBBB) 形态,QRS过渡,左心室激活时间 (LVAT),间峰间隔和QRS持续时间.
主要成果:
- 该研究包括73名患者,在所有情况下都取得了成功的LBBAP.
- 经过修改的胸部导向与EP系统对RBBB形态和QRS过渡的100%一致.
- 虽然MCL测量显示QRS持续时间和LVAT偏差轻微但最小,但通过类内相关系数 (0.849为QRS持续时间,0.850为LVAT) 确认了强烈的一致性.
结论:
- 在LBBAP植入期间,修改的胸部监测与传统的EP系统密切相关.
- MCLs代表了EP系统的实用和可靠的替代方案,在资源有限的环境中尤其有利.
- 这种方法可以提高LBBAP程序的可访问性,而不会影响监控质量.

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
