Atrial electrophysiological abnormality in patients with Brugada syndrome assessed by P-wave signal-averaged ECG and programmed atrial stimulation.
BACKGROUND There is evidence that some patients with Brugada syndrome (BS) exhibit atrial tachyarrhythmias including paroxysmal atrial fibrillation. We investigated whether BS associated not only with vulnerability to ventricular fibrillation, but also with vulnerability to atrial fibrillation. METHODS AND RESULTS In 15 patients with BS and Brugada-type electrocardiogram (ECG) (14 men, 1 woma...

متن کاملsignal-averaged electrocardiography in patients with advanced heart failure: a better indicator of left ventricular enlargement compared with conventional electrocardiography
background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...
متن کاملSignal averaged electrocardiography and renal function in hypertensive patients
Abnormal signal averaged electrocardiograms (SAECGs) and late ventricular potentials (LVPs) are predictors of sudden cardiac death. The present study hypothesized that SAECGs are impaired in hypertensive patients with renal failure. A total of 30 patients with grade 2 hypertension underwent SAECG. Serum level of creatinine and glomerular filtration rate (GFR) were also assessed. At least one SA...
متن کاملAtrial fibrillation and atrial vulnerability in patients with Brugada syndrome.
OBJECTIVES We sought to study atrial vulnerability in patients with Brugada syndrome. BACKGROUND Atrial fibrillation (AF) often occurs in patients with Brugada syndrome, but atrial vulnerability in Brugada syndrome has not been evaluated. METHODS The patient group consisted of 18 patients with Brugada syndrome. The control group consisted of 12 age- and gender-matched subjects who had neith...
