概括
同时的双心室节拍 (LVRV节拍) 和左心室 (LV) 领先预激活节拍 (LV30RV节拍) 在心力衰竭患者中显著改善了心室间同步. 这些CRT节奏策略增强了心室内和心室间的机械同步.
科学领域:
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 心脏再同步疗法 (CRT) 旨在改善心室内膜异步.
- 对于CRT对心室间异步的作用尚不清楚.
- 这项研究评估了在各种CRT节奏配置期间的双心脏机械同步.

- 四种节奏模式的比较:自己的/右心室 (RV) 节奏,同时的LVRV节奏,LV30RV节奏和LV节奏.
- 使用激活成像 (AI) 来量化机械传播,以测量腹腔间差异 (LV-RV差异) 和分散 (AI-SD).
主要成果:
- 与LVRV,LV30RV和LV节奏相比,自己的/RV节奏显示出明显更大的腹腔间异步 (LV-RV差异).
- 与Own/RV和LV节拍相比,LVRV和LV30RV节拍在两个心室中显著降低了AI-SD.

Correlation between ECG and Cardiac Cycle
8.4K
The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Imaging Studies for Cardiovascular System I:Echocardiography
492
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
