Repetitive ventricular response. Prevalence and prognostic significance.
SUMMARY The purpose of this study was to determine the prevalence of repetitive ventricular responses caused by non-bundle-branch re-entry and bundle-branch re-entry in 47 patients with and in 50 patients without ventricular tachycardia. We also compared the prevalence of repetitive ventricular responses using two types of electrophysiological stimulation: single premature ventri-cular stimulat...
متن کاملThe clinical significance of the repetitive ventricular response.
THE CLINICAL SIGNIFICANCE of the repetitive ventricular response (RVR) has become an issue of considerable interest and controversy.'-6 Despite the interest and efforts of several investigators, definite conclusions about its significance are not possible. In fact, the clinical and electrophysiologic aspects of the RVR have been a source of confusion, particularly for those not well acquainted ...
متن کاملPrognostic significance of right ventricular extrasystoles.
UNLABELLED Extrasystoles (RVES) from the right ventricular outflow tract (RVOT) are a common arrhythmia in routine ECGs. METHODS In this prospective study 56 consecutive patients with RVES (22 males, 34 females) were examined for morphological and/or functional right ventricular (RV) abnormalities by 12-lead, Holter, exercise ECGs, transthoracic echocardiography and signal averaging. The foll...
متن کاملPrevalence and Prognostic Significance of Left Ventricular Dysfunction in Patients Presenting Acutely with Atrial Fibrillation
CONDENSED ABSTRACT The prevalence and prognostic importance of CM occurring as a consequence of AF is poorly defined. This study investigated the incidence of CM in patients with AF, its clinical features and long-term outcomes. We demonstrated that CM is common in patients presenting acutely with newly diagnosed rapid AF, and carries a worse long-term prognosis. Systolic dysfunction was revers...
متن کاملPrevalence and prognostic significance of left ventricular reverse remodeling in dilated cardiomyopathy receiving tailored medical treatment.
OBJECTIVES The purpose of this study was to determine the prevalence and prognostic role of left ventricular reverse remodeling (LVRR) in idiopathic dilated cardiomyopathy (IDCM). BACKGROUND Tailored medical therapy can lead to LVRR in IDCM. The prevalence and prognostic impact of LVRR remain unclear. METHODS We consecutively enrolled 361 IDCM patients. LVRR was defined as a left ventricula...
