- 之前的研究并没有将UHF-ECG与白心患者的其他异步评估方法进行比较.
研究的目的:
- 为了比较UHF-ECG衍生的腹腔间电失调 (e-DYS) 与心声学测量的腹腔间机械延迟 (IVMD).
- 评估这些方法在接受右心室节拍 (RVP) 或导电系统节拍 (CSP) 的患者中.
主要方法:
- 对53名患有晚期心导电疾病和保存的喷射分数的患者进行前性研究.
- 患者被分配到RVP (n=32) 或CSP (n=21).

Disturbances in Heart Rhythm
866
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.

Pulse rhythm
754
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Mechanism of Cardiac Arrhythmias
872
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.
