概括
左心室辅助装置 (LVAD) 植入可能会影响可植入心脏转动器 (ICD) 功能,特别是在较新的右心室导线患者中. 在LVAD手术后,密切的术后ICD监测至关重要.
科学领域:
- 心脏病学
- 医疗器械
- 心脏衰竭的治疗方法
背景情况:
- 左心室辅助器件 (LVAD) 在晚期心力衰竭中很常见.
- 大多数使用LVAD的患者已经使用了可植入心脏转动器 (ICD).
- 靠近右心室除线的LVAD输入可能会破坏ICD功能.
研究的目的:
- 评估LVAD植入对ICD功能的影响.
- 评估LVAD手术后RV参数的变化.
- 在LVAD后确定ICD功能障碍的危险因素.
主要方法:
- 对95名接受LVAD植入的ICD患者进行了回顾性分析.
- 在手术前和手术后的RV导向参数的比较 (传感幅度,阻抗,捕获值).
- 根据RV的年龄对参数进行分层 (≤2年 vs>2年).
主要成果:
- 植入LVAD显著降低了传感幅度和高压阻抗,并增加了捕获值.
- 两年前的RV电线显示高电压阻抗显著下降.
- ICD的机械破坏是罕见的,但显著的.
结论:
- 植入LVAD可能会改变ICD的功能并导致机械中断.
- 在LVAD植入后,建议对术前ICD进行密切监测和询问.
- 视频转换器的使用年龄可能会影响LVAD手术对ICD参数的影响.

Cardiomyopathy V: Interprofessional Care
33
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy II: Dilated Cardiomyopathy
22
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Electrocardiogram Fundamentals

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.
Parts of an ECG
An ECG utilizes electrodes on the skin...
