متن کاملIdiopathic sustained left ventricular tachycardia: clinical and electrophysiologic characteristics.
Electrophysiologic studies were performed in 16 patients 11 to 45 years old (mean 33 years) with idiopathic sustained (lasting more than 5 min) ventricular tachycardia (VT) originating from the left ventricle. Endocardial mapping during VT showed that the earliest site of activation was at the apical inferior portion of the left ventricle in 14 patients whose QRS morphology during VT showed a r...
متن کاملIdiopathic Ventricular Tachycardia of Left Ventricular Origin
Background. The signal-averaged ECG has been used to detect late potentials, and it is considered a noninvasive marker for areas of slow conduction requisite for reentrant arrhythmia. Late potentials are not usually found in patients with idiopathic ventricular tachycardia (VT); nevertheless, fragmented electrograms are often recorded in those patients during endocardial mapping. The purpose of...
متن کاملLeft ventricular function during pregnancy.
As emphasized by Watkins et al.,9 the variability in plasma renin activity in CHF is explained by the degree of compensation in maintaining arterial pressure and plasma volume; the latter measurement was not obtained in the Curtiss or Gavras study. The observations in these two recent studies reaffirm the importance of the RAA system in maintaining systemic vascular resistance (SVR) in CHF. Cur...
