2015年5月1日 · Vectorcardiography (VCG), as an alternative to standard 12-lead electrocardiography (ECG), represents the electrical activity of the heart. Previous studies on VCG document that VCG criteria for the diagnosis of, for example, myocardial infarction (MI), ventricular hypertrophy and ischemic diseases, are superior to the corresponding 12-lead ECG ...
Vectorcardiography - Wikipedia
Vectorcardiography (VCG) is a method of recording the magnitude and direction of the electrical forces that are generated by the heart by means of a continuous series of vectors that form curving lines around a central point.
Present results and methods of vectorcardiographic diagnostics of ...
2024年2月1日 · We created a comprehensive and clear overview of VCG methods. We highlighted advantages of VCG over the standard 12-leads ECG. We compared performance of individual methodologies. We investigated potential reserves for future research.
Selected transformation methods and their comparison for VCG …
2022年5月1日 · The use of vectorcardiography in clinical practice is not common, but VCG leads can be derived from 12-lead ECG. VCG has proven to be a useful and more accurate tool for diagnosing various heart diseases within automated detection.

2017年9月5日 · In this work, we explore a novel ECG representation based on vectorcardiogram (VCG), called temporal vectorcardiogram (TVCG), along with a complex network for feature extraction. We also...
心电图、心电向量图与冠状动脉造影结果对比分析
2011年5月3日 · 摘要: 目的:通过分析心电图(Electrocardiogram,ECG)和心电向量图(Vectorcardiogram,VCG)的改变与冠脉造影(CAG)结果进行对比,探讨ECG、VCG在冠状动脉病变中的诊断价值。方法: 选择2008年1月~2009年12月临床拟诊断为冠心病患者108例,行常规ECG、VCG检查,并于1周内进行CAG ...
Spatiotemporal representation of cardiac vectorcardiogram (VCG…
2012年3月30日 · VCG surmounts not only the information loss from only one or two ECG signals but also the dimensionality problems induced by the 12-lead ECG signals. In this paper, we propose a new dynamic display of VCG to characterize both spatial and temporal patterns of cardiac electrical activities as an alternative for the conventional 12-lead ECG.
Comparison of Different Electrocardiography with …
Vectorcardiography (VCG) is an investigation method that was previously compared to ECG several times and was evaluated as a useful investigation method [1, 2, 3]. It achieved a higher sensitivity for the detection of hypertrophy as well as ischaemic heart disease [4, 5, 6, 7].
