Spatiotemporal representation of cardiac vectorcardiogram (VCG) signals
BACKGROUND Vectorcardiogram (VCG) signals monitor both spatial and temporal cardiac electrical activities along three orthogonal planes of the body. However, the absence of spatiotemporal resolution in conventional VCG representations is a major impediment for medical interpretation and clinical usage of VCG. This is especially so because time-domain features of 12-lead ECG, instead of both spa...
متن کاملThe vectorcardiogram of cardiac infarction.
A simple method of drawing the three-plane projection of the spatial vectorcardiogram has been described (Shillingford and Brigden, 1951). A series of normal vectorcardiograms were studied and found to have certain constant characteristics that were comparable with the results obtained by electronic methods. In this paper we report the vectorcardiographic findings of extensive cardiac infarctio...
متن کاملRelating the spectrum of cardiac signals to the spatiotemporal dynamics of cardiac sources
An increasing number of studies use the spectrum of cardiac signals for analyzing the spatiotemporal dynamics of complex cardiac arrhythmias. However, the relationship between the spectrum of cardiac signals and the spatiotemporal dynamics of the underlying cardiac sources remains to date unclear. In this paper, we derive a mathematical expression relating the spectrum of cardiac signals to the...
متن کاملdetection and classification of cardiac ischemia using vectorcardiogram signal via neural network
background: various techniques are used in diagnosing cardiac diseases. the electrocardiogram is one of these tools in common use. in this study vectorcardiogram ) vcg ( signals are used as a tool for detection of cardiac ischemia. methods: vcg signals used in this study were obtained form 60 patients suspected to have ischemia disease and 10 normal candidates. verification of the ischemia had ...
متن کاملDerivation of McFee-Parungao Orthogonal Leads from Standard Electrocardiogram
The study aim was to construct linear transformations for derivation of McFeeParungao vectorcardiogram (VCG) from 12 standard ECG or Frank VCG and to assess the accuracy of derived electric cardiac signals (ECS) and secondarily derived VCG parameters. A large archive of VCG data recorded in the McFee-Parungao lead system have been accumulated and analyzed in the Cardiology Research Complex (Mos...
