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 کاملNonsustained Ventricular Tachycardia in Hypertrophic Cardiomyopathy
Spirito et all report on the prognostic significance of nonsustained ventricular tachycardia (VT) during Holter monitoring in a highly selected cohort of 151 asymptomatic patients with hypertrophic cardiomyopathy (HCM). Patient selection excluded patients with moderate to severe symptoms (New York Heart Association functional classes III and IV), those with previous syncopal episodes, and those...
متن کاملPrediction of long-term outcomes by signal-averaged electrocardiography in patients with unsustained ventricular tachycardia, coronary artery disease, and left ventricular dysfunction.
BACKGROUND An abnormal signal-averaged ECG (SAECG) is a noninvasive marker of the substrate of sustained ventricular tachycardia after myocardial infarction. We assessed its prognostic ability in patients with asymptomatic unsustained ventricular tachycardia, coronary artery disease, and left ventricular dysfunction. METHODS AND RESULTS A blinded core laboratory analyzed SAECG tracings from 1...
متن کاملCardiac Arrest or Ventricular Tachycardia Insights From Endocardial Mapping and Signal-Averaged Electrocardiography
Background. Many studies have combined patients with hemodynamically well-tolerated ventricular tachycardia (VT) and those with cardiac arrest (CA) as a single, homogenous group. Recent studies suggest that these two groups have different electrophysiological substrates and responses to therapy. Most of these studies, however, enrolled patientswith a variety of cardiac diagnoses. Methods and Re...
