Detection of concealed left sided accessory atrioventricular pathway by P wave signal averaged electrocardiogram.
OBJECTIVES The purpose of this study was to examine whether P wave signal-averaged electrocardiogram (P-SAECG), which detects subtle changes in P wave, detects the concealed accessory atrioventricular pathway (AP). BACKGROUND It is difficult to differentiate atrioventricular reciprocating tachycardia (AVRT) due to the AP from atrioventricular nodal reentrant tachycardia (AVNRT) when the ventr...
متن کاملEffect of haemodialysis on signal-averaged electrocardiogram P-wave parameters.
BACKGROUND The P-wave signal-averaged electrocardiogram (SAECG) is a non-invasive technique considered to indicate an increased risk for paroxysmal atrial fibrillation. The study was designed to evaluate the effect of the haemodialysis (HD) process on SAECG parameters in the group of selected HD patients. METHODS Forty-seven HD patients (without relevant cardiac diseases) were included. SAECG...
متن کاملDetection of patients at risk for paroxysmal atrial fibrillation during sinus rhythm by P wave-triggered signal-averaged electrocardiogram.
To determine whether patients at risk for paroxysmal atrial fibrillation could be detected while in sinus rhythm, the signal-averaged electrocardiogram triggered by P waves was recorded in 42 patients with paroxysmal atrial fibrillation (Paf group) and in 50 control patients. The root mean square voltages (LP10, LP20, and LP30) for the last 10, 20, and 30 msec and the duration (Ad) of filtered ...
متن کاملP wave signal-averaged electrocardiogram as a new marker for atrial tachyarrhythmias in postoperative Fontan patients.
OBJECTIVES This study was undertaken to determine the potential role of P wave signal-averaged electrocardiogram (PSAECG) for risk assessment of atrial tachyarrhythmias (ATs) in patients after Fontan operation. BACKGROUND Onset of atrial flutter/fibrillation (AFF) in patients who have undergone Fontan operation for univentricular hearts constitutes an unfavorable clinical event associated wit...
متن کاملNew Parameter to Predict Recurrence of Paroxysmal Atrial Fibrillation after Pulmonary Vein Isolation by the P-Wave Signal-Averaged Electrocardiogram
Noninvasive methods for predicting the recurrence of atrial fibrillation (AF) after initial pulmonary vein isolation (PVI) have not been well described. The aim of the present study was to evaluate the usefulness of the P-wave signalaveraged electrocardiogram (P-SAECG) in predicting the recurrence of AF after initial PVI. The P-SAECG was recorded before and after (within 1 week) the initial PVI...
