Cardiac Electrophysiology Review

The idea of analyzing P wave inscriptions to discriminate between patients with different diseases isnot new. Whereas standard approaches deal mainly with an analysis of the duration of the P wave, there is anincreasing interest for the P wave morphology. Detailed analysis of the low voltage P wave will require ahardware setup that enables high-quality signal acquisition with low noise interference in combination with anECG subtraction technique. The feasibility of the surface ECG to detect the presence of an abnormalelectrophysiological substrate in the atrial myocardium as well as to localize ectopic atrial rhythms will beenhanced by use of P wave morphological analysis.
