“…Prolonged iltered P-wave duration (FPD) in P-wave signal-averaged electrocardiography has been used as a noninvasive, powerful predictor of AF, the irst episode and recurrences, in lone, occult or silent atrial ibrillation, in stroke, heart failure, hypertension, hypertrophic cardiomyopathy, hypothyroidism and in patients undergoing coronary artery bypass surgery [44][45][46]. A prolonged SAECG P-wave duration was also mentioned in septal atrial defect, especially in patients who experienced AF, not corrected after atrial septal defect closure, and it was demonstrated that atrial conduction disturbances occur early, requiring an early intervention to prevent the development of late AF ( Table 2) [47].…”

“…There is no consensus about the cut-of point for FPD, which was 121 ms in hypertensive patients Auriti et al [48], 124 ms in patients in sinus rhythm, 136 ms in hypertensive patients with a history of atrial ibrillation, 132 ms in patients with COPD, and 155 ms in several other studies [43,45,46,49], diferences related to diferent averaging and iltering methods [45].…”

Signal-averaged ECG (SAECG) is a high-resolution, noninvasive electrocardiographic method enabling detection of late ventricular potentials (LVP), which are low-amplitude and high-frequency signals, predicting reentry ventricular arrhythmias, and sudden cardiac death (SCD). Three criteria are used to detect late ventricular potentials as follows: signal-average ECG QRS duration (SAECG-QRS), the duration of the terminal part of the QRS complex with an amplitude below 40 μV (LAS40) and the root mean square (RSM) signal amplitude of the last 40 ms of the signal < 20 μV (RMS40). Late ventricular potentials can be detected not only at the end of a QRS complex but also as intra-QRS (IQRS) potentials. Signal-averaged ECG was modiied to enable the analysis of the P-wave and to detect atrial late potentials (ALPs), low-amplitude potentials at the terminal part of the iltered P-wave, and predictors of atrial ibrillation (AF). Late atrial and ventricular potentials originate from areas of delayed, fragmented, and heterogenous conduction within atrial or ventricular myocardium. This chapter reviews the most important mechanisms explaining the occurrence of late ventricular, intra-QRS, and atrial potentials; their predictive value for arrhythmia, focusing on recent clinical data, long-term follow-up, and outcome; and analysis of SAECG variables in cardiac and noncardiac diseases.

“…Maximum P wave duration and PWD are non-invasive markers that show the heterogeneous and unstable distribution of stimulations originating from the sinus node on the atrium wall. 6,7 There is a growing recognition that LV dysfunction is associated with marked alternation in the electro physiologic properties of the myocardium which is the precursor of the cardiac conduction and rhythm abnormalities. Several ECG indicators have been investigated to predict the occurrence of arrhythmia in patients with left ventricular dysfunction.…”
