A study of electrode-tissue impedances encountered in cardiac pacing
Any study of the electrical properties of electrodeelectrolyte systems is rendered difficult by their dependance on, amongst other things, electrode history, electrode surface finish, electrode geometry, electrode area, electrolyte composition and the frequency and amplitude of the applied signal. …

Parameters and algorithms to evaluate cardiac mechanics by conductance catheter
… mechanical dyssynchrony: its impact on cardiac function, the therapy for its treatment and the methods for its quantification. Specifically, we describe the conductance catheter and its use for the measurement of dyssynchrony. At the end of the Section 1, we propose a new set of indexes …

New Foundations for Pacing the Stomach
The use of electrical pacing and high-resolution (HR) mapping continues to advance our understanding of gut motility in health and disease. However, the efficacy and effectiveness of gastric pacing remains limited in clinical practice. In the stomach, omnipresent bioelectrical events known as …

Heart failure and associated structural and functional remodeling: assessment employing various magnetic resonance imaging methodologies.
… magnetic resonance imaging (MRI), or cardiac MR, is currently considered the "gold" standard for noninvasively characterizing cardiac function and viability, having 3D capabilities and a high spatial and temporal resolution. More recently, the capabilities of MRI have been extended to …

A 12-month retrospective descriptive analysis of a single helicopter emergency medical service operator in four South-African provinces
… fibrinolysis, defibrillation, cardioversion or cardiac pacing. Almost all patients received intravenous fluid therapy (n=867, 94.7%). The administration of sedation (n=430, 46.9%) and analgesia (n=329, 35.9%) were also common interventions. Conclusion: By describing current HEMS transport …

The role of myocardial fibrosis and ventricular mechanical dyssynchrony in the pathogenesis and treatment of contractile myocardial dysfunction.
… of systolic heart failure, and its treatment by cardiac resynchronisation has been proven efficacious in selected patients with systolic left ventricular dysfunction. Despite emerging evidence implicating myocardial fibrosis and ventricular dyssynchrony in heart failure, their causal relationship …
