متن کاملProcainamide-induced changes in reentrant ventricular tachycardia with special reference to the tachycardia-interrupting critical paced cycle length during transient entrainment with rapid pacing.
With rapid ventricular pacing, sustained ventricular tachycardia (VT) is often entrained and interrupted at a critical paced cycle length. In this paper, the possible mechanism and determinant of the critical cycle length interrupting VT are addressed. Sixteen consecutive patients underwent rapid ventricular pacing in 18 morphologically distinct sustained VTs before and after procainamide. The ...
متن کاملPredicting ventricular tachycardia cycle length after procainamide by assessing cycle length-dependent changes in paced QRS duration.
To determine if paced cycle length-dependent changes in the QRS duration correlate with the change in ventricular tachycardia (VT) cycle length after procainamide, we measured the QRS duration during sinus rhythm and during right ventricular pacing before and after procainamide (mean concentration, 9.9 micrograms/ml) in 18 patients with morphologically identical VT induced at both study periods...
متن کاملSelf-Paced Curriculum Learning
Curriculum learning (CL) or self-paced learning (SPL) represents a recently proposed learning regime inspired by the learning process of humans and animals that gradually proceeds from easy to more complex samples in training. The two methods share a similar conceptual learning paradigm, but differ in specific learning schemes. In CL, the curriculum is predetermined by prior knowledge, and rema...
متن کاملSelf-Paced Co-training
Notation and Definition: We assume that examples are drawn from some distributions D over an instance space X = X1 × X2, where X1 and X2 correspond to two different “views” of examples. Let c denote the target function, and let X and X− (for simplicity we assume we are doing binary classification) denote the positive and negative regions of X , respectively . For i ∈ 1, 2, let X i = {xj ∈ Xi : ...
