1. T-vector and T-loop morphology analysis of ventricular repolarization in ischemic heart disease
Abstract : Background: Sudden cardiac death (SCD) is responsible for about half of all cardiovascular deaths in the western world. Heterogeneous ventricular repolarization (VR) is a common denominator in the genesis of malignant ventricular arrhythmias responsible for SCD and the presence of coronary artery disease (CAD) is an aggravating factor.

2. Ventricular repolarization in the human heart : effects of pharmacological and non-pharmacological interventions
Abstract : Ventricular arrhythmias is the main cause of sudden cardiac death. A prolonged repolarization might cause such arrhythmias, and an increased understanding about mechanisms is therefore important for their primary and secondary prevention. READ MORE

3. Cardiac memory studies in two human models
Abstract : Background: Cardiac memory is a form of electrical remodeling of the ventricles, where the T vector follows ("remembers') a previously altered QRS vector. On the electrocardiogram (ECG), it presents as T-wave inversions. READ MORE

4. Frequency Analysis of Sampled-Data Systems Applied to a Lime Slaking Process
Abstract : Single-rate and multirate sampled-data (SD) systems as well as linear time periodic (LTP) systems with discrete jumps are analyzed in the frequency domain. The focus of the analysis is both on rejection of disturbances and on robust stability properties. READ MORE

5. Porcine myocardial ischemia-reperfusion studies on cardioprotection, ventricular arrhythmia and electrophysiology
Abstract : Background: Coronary artery disease is the primary cause of death in adults in the industrialised world and ventricular fibrillation associated with myocardial ischemia is the main cause of sudden cardiac death. Restoration of blood flow and preservation of myocardial integrity throughout ischemia and reperfusion is essential to improve clinical outcome. READ MORE
