2024年10月8日 · Home ECG Library ECG Diagnosis A premature ventricular complex (PVC) is a premature beat arising from an ectopic focus within the ventricles. AKA: ventricular ectopics, ventricular extrasystoles, ventricular premature beats, ventricular premature depolarisations.

The electrical events of the heart detected by the electrocardiogram (ECG) allow a PVC to be easily distinguished from a normal heart beat. However, very frequent PVCs can be symptomatic of an underlying heart condition (such as arrhythmogenic right ventricular cardiomyopathy ).

2023年3月22日 · 文章设计了一种基于MatLab和STM32F103微控制器的12导联心电图（ECG）信号采集系统。 心电图信号是诊断心脏疾病的重要依据，因此，其准确的采集、分析 和 处理对于医务工作者 和 科研人员来说极为重要。

This paper deals with transformations from electrocardiographic (ECG) to vectorcardiographic (VCG) leads. VCG provides better sensitivity, for example for the detection of myocardial infarction, ischemia, and hypertrophy.

Explore comprehensive insights on PVCs, ECG rhythms, and ventricular extrasystoles, including classification, pauses, and Lown's grading for accurate diagnosis.

1992年1月1日 · Since our own interpretation program MEANS (Modular ECG Interpretation System) consists of two independent versions, one for the 12-lead ECG and one for the Frank VCG,"' we formulated several questions: (1) would the combined diagnostic classifications of the ECG program and VCG program reveal better results than either one; (2) in this ...

2023年4月3日 · Ventricular premature complexes (VPCs), or premature ventricular complexes/contractions (PVCs), are ectopic beats that arise from within the ventricles. They are common and can occur in a wide variety of clinical scenarios and a diverse population. They can present in patients both with and without preexisting cardiac disease. [1] .

2019年8月19日 · An ECG demonstrates sinus rhythm with premature ventricular contractions (PVCs) of left bundle branch, inferior axis morphology (Figure [A]). A monitor reveals a 33% PVC burden, and an echocardiogram is normal.
