Abnormalities of Electrocardiographic P Wave Morphology and Their Relation to Electrophysiological Parameters of the Atrium in Patients with Sick Sinus Syndrome

Abstract: We examined the incidence of long P wave duration in lead II and increased P terminal force in lead V1 (PTFV1), and their relationship to electrophysiological findings of atrial muscle in 34 patients with sick sinus syndrome (SSS). Patients were divided into three groups: Group I, consisting of 20 patients with various cardiac arrhythmias other than SSS and paroxysmal atrial fibrillation (PAF) who served as controls; Group II, consisting of 18 patients with SSS but without PAF; and Group III consisted of 16 pa… Show more

“…Previous investigations have shown that electrical abnormalities, primarily intra-atrial or interatrial conduction delay or block are reflected by P-wave changes on the surface ECG [56][57][58]. Over the last 10 years numerous investigations have explored the role of P wave analysis in order to predict AF from individuals in sinus rhythm reaching sensitivities and specificities of about 80% [59].…”

“…These have observed the occurrence of prolonged P-wave duration with prolonged and fractionated atrial electrograms. 12,13 These abnormalities have been observed during both sinus rhythm and atrial pacing, with a suggestion that patients who had associated AF had a wider distribution of abnormal atrial findings. De Sisti et al 14 retrospectively reviewed patients with SND who had electrophysiological assessment and found no change in ERP at the high RA at a CL of 600 ms but significant increase in electrogram duration both during the drive CL and extrastimulus compared with controls.…”

“…11 Prolonged P wave duration is not uncommon in patients with sick sinus syndrome and paroxysmal atrial fibrillation and has been attributed not only to left atrial enlargement, but also to prolonged intra-and interatrial conduction delay. 12 Several studies have shown that in patients with interatrial conduction delay, P wave duration can be shortened by atrial septal 2,4,13 and bifocal 1,14 right atrial pacing, and that this resynchronization of left and right atrial activation accompanies a reduction in the number and duration of atrial fibrillation episodes. 3,7,15 Especially in patients with heart failure, improved atrial synchronization may increase cardiac output similar to optimized right-and left-sided AV timing.…”
