2024年10月8日 · Electrophysiology of Ventricular Ectopics. Appropriate discordance describes a pattern of repolarisation abnormality (typically seen with left bundle branch block, paced rhythms, VT) in which the ST segment and T wave are directed opposite to …

24小时动态ECG记录证实心率与VEB是正相关者，预示病人可以从β-阻滞剂获益，但并不足以排除试用其他药物，其次可选用慢心律和 双异丙吡胺。 妥克律、奎尼丁、普鲁卡因酰胺和乙胺碘呋酮等长期应用有明显毒性，通常不适用于治疗VEB。 氟卡尼抑制VEB有很好疗效，但在治疗心肌梗死后的VEB病人（通常是无症状的）反使存活率减低。 该药对治疗有症状的VEB的地位尚在评估。 室性异位搏动，名词，归属于心血管系统，属医学术语。

Ventricular ectopic beats (VEBs) are commonly seen in daily clinical practice. They are largely asymptomatic but can cause upsetting symptoms in some patients. In normal hearts, their occurrence is usually associated with no clinical significance.

2022年7月7日 · Supraventricular ectopic beats (SVEB) or ventricular ectopic beats (VEB) is one of the most common arrhythmia (Paudel and Paudel 2013), which is mainly manifested by changes in the RR interval and/or QRS waveform, the increase in these beats may be a precursor to stroke or sudden cardiac death (Oster et al 2015).

2023年7月12日 · This article presents a novel signal processing framework for detecting VEB (VEB) cardiac episodes using a cross-database, i.e., a trained classification model with an open-source database was used for predicting the VEB episodes from the proprietary database.

2013年6月23日 · VPBs are associated with numerous cardiac diseases (e.g. structural heart disease, ischemia, congenital arrhythmias, pulmonary disease). However, VPBs are also relatively common in patients without known heart disease. The importance of VPBs for prognosis is …

Two simple algorithms for supraventricular (SVEB) and ventricular ectopic beat (VEB) detection using the electrocardiogram (ECG) are presented. Both algorithms use time-domain features and a linear classifier. The first algorithm requires QRS detection only and the second algorithm requires P, QRS a …

A ventricular ectopic beat (VEB) is an extra heart-beat originating in the lower chamber of the heart. This beat, also called a premature ventricular contraction (PVC), occurs before the beat triggered by the heart's normal function.

2020年4月17日 · Ventricular ectopic beats (VEBs) are common. Frequent (>60/hr or 1/min) in healthy subjects has an estimated prevalence of one to four percent in the general population. Over 10 percent on a Holter monitor is considered a high VEB burden. Monomorphic VEBs represent a focal arrhythmia arising from a single site.
