Signal-Averaged Electrocardiogram Improved Identification of Late Potentials
Background. This study performed a critical analysis of signal-averaging methods. The objective was to optimize detection of late potentials. Methods and Results. We studied two patient populations: a low-arrhythmia-risk group with no evidence of heart disease and a group with clinically documented ventricular tachycardia (VT). Filtered QRS duration (QRSD) and terminal QRS amplitude (RMS40) wer...
متن کاملEvaluation of myocardial ischemia in Kawasaki disease by dobutamine stress signal-averaged ventricular late potentials.
OBJECTIVE To determine the possibility of diagnosing myocardial ischemia from signal-averaged electrocardiographic late potentials (LPs) in patients with Kawasaki disease. METHODS Dobutamine stress LPs were obtained in 85 children with a history of Kawasaki disease (48 without coronary artery lesions, 19 with coronary artery lesions without myocardial ischemia, and 18 with myocardial ischemia...

متن کاملApplication of signal-averaged electrocardiogram to myocardial damage in the late stage of Kawasaki disease.
BACKGROUND Myocardial damage occurs in the late stage of Kawasaki disease (KD) regardless of whether coronary artery lesions (CALs) are present. METHODS AND RESULTS A signal-averaged electrocardiogram (ECG) was performed in 23 patients who were in the late stage of KD (CAL was found in 12 and no CAL (non-CAL) was found in 11) and 10 healthy controls. Filtered QRS duration and the root-mean-sq...
متن کاملTime domain analysis of the signal averaged electrocardiogram to detect late potentials in heart failure patients with different etiologies.
OBJECTIVE To evaluate the frequency, clinical correlations and prognosis influence of late potentials on the of heart failure patients with different etiologies using the signal averaged electrocardiogram. METHODS A 42 month study of the signal averaged electrocardiograms of 288 heart failure patients with different etiologies was conducted. The group of patients included 215 males (74.65%) a...
