Abnormal signal-averaged electrocardiograms (SAE) in dilated cardiomyopathy (DCM) was reported to be associated with increased myocardial fibrosis. To elucidate whether the effectiveness of long-term β-blocker therapy for DCM could be predicted by SAE, we prospectively studied 16 consecutive DCM patients without bundle branch block. At the entry, 8 of the 16 patients had normal SAE, which was defined...
P wave signal-averaged ECG (P-SAE) using only orthogonal leads has been useful to detect patients (pts) at risk for paroxysmal atrial fibrillation (Paf). To determine whether the detection accuracy of Paf pts would be enhanced by body surface mapping of P-SAE, we studied 55 Paf pts and 45 control pts. P-SAE was recorded with the P wave-triggering method from the orthogonal leads and 16 precordial...
Background: Abnormal signal-averaged ECG (SAE) in idiopathic dilated cardioomyopathy (DCM) was reported to be associated with increased myocardial fibrosis, which might be induced in part by apoptosis of myocardial cell. To elucidate the pathogenesis of the abnormal SAE in DCM patients, we examined the relation between apoptosis and abnormal SAE in 24 DCM patients.Methods: Spectral turbulance analysis...
Although the incidence of late potentials (LP) in patients (pts) with acute myocardial infarction (AMI) would be decreased by reperfusion therapy, the relation between LP and myocardial viability of MI site after reperfusion therapy remains unclear. To determine the relationship, we studied 34 pts with first AMI and direct PTCA within 4 +/- 15 (1-48) hours after the onset. These pts underwent signal-averaged...
We reported that patients (pts) with paroxysmal atrial fibrillation (Paf) would have temporal and spatial dispersion of atrial depolarization increased, by use of body surface mapping of the P wave signal-averaged ECG (P-SAE). To determine whether the efficacy of pilsicainide (PC), a new Class Ic drug, on Paf attacks could be predicted in view of the dispersion, we prospectively studied 25 symptomatic...
