TWO-STAGE PRECONDITIONERS FOR INEXACT NEWTON METHODS IN MULTI-PHASE RESERVOIR SIMULATION (2007)
Mary Wheeler, H Ector, Kl Ie, Marcelo Ram, Mary F. Wheeler
Abstract. Two-stage procedures refers to a family of convergent nested or inner-outer iterations. This paper addresses their use as preconditioners in the context of systems of coupled nonlinear...
General Classes Of Control-Lyapunov Functions (2007)
Eduardo D. Sontag, H Ector, Héctor J. SUSSMANN
. The main result of this paper establishes the equivalence between null asymptotic controllability of nonlinear finite-dimensional control systems and the existence of continuous control-Lyapunov...
The response to tilt training was compared in a group of 156 patients below 35 years of age (Group A: mean age 19.4 � 7.2 min 6.5, max 34) to a group of 32 patients above 65 years of age (Group B:...
Dilling-Boer, D., Ector, H., Willems, R., Heidbüchel, H.
We report on a patient in whom an active-fixation pre-shaped atrial lead caused perforation of the right atrial wall, pericardium and pleura, resulting in pericardial effusion and right-sided...
Anné, W., Van Rensburg, H., Adams, J., Ector, H., Heidbüchel, H.
Background Atrial arrhythmias are a frequent complication of atrial surgery. The location of these tachycardias is very diverse due to the individual difference in the original anatomy, surgical...

Aims Heart rate variability has been proposed as an indicator of cardiovascular health. Since women have a lower cardiovascular risk, we hypothesized that there are gender differences in autonomic...
Ector, H., Jordaens, L., Vanhaecke, J.
In clinical practice, observational studies remain necessary for evaluating accepted and new treatments. The comparison of results remains difficult and often controversial, because of a wide...
ACCELEROMETER-BASED ADAPTIVE-RATE PACING - A MULTICENTER STUDY. (1993)

Limits of the Wong-Zakai Type with a Modified Drift Term (1989)
. We study Stratonovich stochastic differential equations driven by an m-dimensional Wiener process W , with m 2. If W is approximated by processes W with more regular sample paths, then it is known...
GEUKENS, R., ECTOR, H., STALPAERT, G., DE GEEST, H.
A Caucasian female patient with repetitive attacks of ventricular tachycardia and fibrillation caused by annular submitral left ventricular aneurysm is reported. During a follow-up period of six...

Fourteen children had a permanent pacemaker implanted between May 1967 and July 1983. Postoperative complete heart block was the indication in nine cases, congenital complete heart block in three,...
Sick sinus syndrome in childhood.
Ector, H, Van Der Hauwaert, L G
The clinical and electrocardiographic findings in five children with the sick sinus syndrome and an otherwise normal heart are described. There were three boys and two girls. Their age at onset of...
Cardiac strangulation, a rare complication of epicardial pacemaker leads during growth.
Eyskens, B., Mertens, L., Moerman, P., Ector, H., Daenen, W., Gewilling, M.
A six year old boy with an epicardial pacing lead since infancy presented with thoracic pain triggered by movement. The pain was thought to be musculoskeletal, but two weeks later he collapsed and...

Objectives: To determine risk factors for the development of atrial fibrillation (AF) after atrial flutter (AFL) ablation; and to study the relation between AF development and periprocedural drug use.
