His bundle recordings were obtained in three patients with histories of recurrent supraventricular tachyeardias and electrocardiograms demonstrating a short P-R interval with a normal QRS (the Lown-Ganong-Levine syndrome). The His bundle electrograms obtained during sinus rhythm demonstrated a normal A-H (atrium-to-His bundle) time in one patient and a low normal A-H time in two patients. The H...

Jockusch, Li and Yang (TAMS 356 (2004), 2557-2568) showed that the Lown and Low1 r.e. degrees are not elementarily equivalent for n > 1. We answer a question they raise by using the results of Nies, Shore and Slaman (PLMS (3) 77 (1998), 241-291) to show that the Lown and Lowm r.e. degrees are not elementarily equivalent for n > m > 1.

Background and Objectives: The aims of this study were to assess the long term overall survival of patients after an acute myocardial infarction (AMI), and to determine the association of survival with the occurrence of ventricular arrhythmia, as recorded by Holter electrocardiography (ECG) and signal-averaged electrocardiography (SAECG). Subjects and Methods: One hundred fifty two patients wit...

Let X/K be an absolutely simple abelian variety over a number field; we study whether the reductions Xp tend to be simple, too. We show that if End(X) is a definite quaternion algebra, then the reduction Xp is geometrically isogenous to the self-product of an absolutely simple abelian variety for p in a set of positive density, while if X is of Mumford type, then Xp is simple for almost all p. ...

I am concerned about the implications of the Editorial by Drs. Lown and Axelrod which appeared in the October 1972 issue of Circulation. Although the authors rightfully point out the numerous technical problems still to be overcome in the development of such defibrillators, their conclusions in the last three paragraphs indicate a heavy bias in favor of "practical research." Although Dr. Lown h...

Since the introduction of closed chest synchronized DC shock treatment for atrial fibrillation by Lown in 1962 (Lown, Amarasingham, and Newman, 1962a; Lown et al., 1962b) many thousands of patients have undergone this treatment. Complications have occurred on occasion. Arrhythmias, some fatal, have been reported by Ross (1964), Morris et al. (1964), Killip (1963), and Turner and Towers (1965). ...

The atrial depolarization pattern was studied in 22 patients with Wolff-Parkinson-White and Lown-Ganong-Levine syndrome. The influence of the accessory pathways on the shape, magnitude and conduction pattern of the PSE loop was analyzed. An accurate evaluation of the beginning of the delta wave and of the P loop distortions was obtained by using high magnification (1 mV = 30 cm) recordings. The...

statement for it is not unlike the statement that we made in the conclusions of our review on page 426. We stated: "There are at present no conclusive data in the medical literature to support the concept that ACBG is superior to adequate medical management to prevent or even ameliorate other signs and symptoms of ischemic heart disease , such as myocardial infarction, arrhythmia and congestive...

Given a family of Abelian varieties over a positive-dimensional base, we prove that for a sufficiently general curve in the base, every rational section of the family over the curve is contained in a unique rational section over the entire base. 1. Main results sec-intro The starting point for this article is the following theorem. Theorem 1.1. [GHMS05, Theorem 6.2] Let B be a smooth, quasi-pro...
