About

It is suggested that P-wave terminal force (Ptf), a product of the amplitude (PAM) and the duration (PT) of the terminal phase of P-wave in lead V1, shows early delay in left atrial conduction, observed earlier that the dilatation of left atrium. The aim is to follow PT, PAM and Ptf changes during 5-year follow-up (5FU) and examine the relation of these changes to the number of AF episodes requiring hospitalisation (HOSP) for restoration of sinus rhythm (RSR).

Full description

Background. It is suggested that P-wave terminal force (Ptf), a product of the amplitude (PAM) and the duration (PT) of the terminal phase of P-wave in lead V1, shows early delay in left atrial conduction, observed earlier that the dilatation of left atrium. Aim. We aim to follow PT, PAM and Ptf changes during 5-year follow-up (5FU) and examine the relation of these changes to the number of AF episodes requiring hospitalisation (HOSP) for restoration of sinus rhythm (RSR). We hypothesise that, in patients with atrial fibrillation (AF): the index parameters (PT, PAM, Ptf), characterising left atrial repolarization, correlates the number of future hospitalisations (HOSP) aimed for restoration of sinus rhythm (RSR) in 5-year follow-up (5FU) in 5FU the number of HOSP aimed for RSR correlates with the progression of left atrium electrical remodelling, expressed as PAM5,PT5, Ptf5 at 5FU.
