Frequency content and characteristics of ventricular conduction. Tereshchenko LG, Josephson ME.  Journal of electrocardiology. 2015; 48(6):933-7.  NIHMSID: NIHMS719824  PMID: 26364232 PMCID: PMC4624499

In this manuscript we review previous studies of QRS frequency content, and discuss our novel method of the conjoint analysis of the ECG signal in six dimensions: in the domain of three space dimensions, in time domain, and in frequency domain. Orbital frequency of QRS loop is introduced as a six-dimensional characteristic of ventricular conduction, which helped to reveal inapparent ventricular conduction, and to characterize electrophysiological substrate.
