Summarize emerging technical methods for surface electrocardiogram analysis and evaluate their research and clinical utility in characterizing atrial and ventricular dynamics during atrial fibrillation.
Reviewed digital signal processing methodologies, including atrial signal extraction and spectral analysis, to determine atrial fibrillatory frequency.
Evaluated ventricular response assessment tools, including heart rate variability, RR-interval histograms, Lorenz plots, and non-linear dynamics.
Atrial fibrillatory rate measured noninvasively correlated strongly with intra-atrial cycle length, with lower rates associating with spontaneous termination and higher rates indicating therapy resistance.
Ventricular response profiling and autonomic tone assessment facilitated functional evaluation of the atrioventricular node and predicted responsiveness to cardioversion, antiarrhythmic drugs, and ablation.
