Techniques and Problems in Correlating Cellular Electrophysiology and Morphology in Cardiac Nodal Tissues

1978
It is evident that it is very difficult to predict the functional behaviour of a cell, or a group of cells, on the basis of morphological data alone. It is equally clear that one cannot be informed of the cellular morphology of a particular part of the heart when only electrophysiological information is available.

Electrophysiology Related to Cardiac Pacing Techniques

1979
Bradycardias originate either from a dysfunction of impulse formation in the sinoatrial node or from a disturbed conduction of the impulse. A decrease in the rate of the sinoatrial node automaticity may be caused by an increased duration of the action potential, an increase in the maximum diastolic potential (i.e.

A dual energy mode system for the development of new techniques in cardiac electrophysiological studies and external pacing

Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136), 2002
Programmed electrical stimulation is an important clinical procedure in the assessment of bradycardias and ventricular tachycardias. At present, research is been carried out on a minimally invasive approach of this procedure. Therefore, the authors have developed a PC based system which is suitable for the development and clinical validation of new non-

Evaluation of a T1 mapping technique for stratifying patient risk: A preliminary study using computer simulations of cardiac electrophysiology

2016 IEEE EMBS International Student Conference (ISC), 2016
Heterogeneous scarred tissue, or infarct, stemming from coronary artery occlusion has been linked to ventricular tachycardia (VT). Myocardial infarct (MI)-based indices derived from contrast enhanced (CE) magnetic resonance have been increasingly investigated to complement the standard risk stratification strategy of patients for implantable ...

Electrophysiologic effects of amiloride in canine Purkinje fibers: evidence for a delayed effect on repolarization.

Journal of Pharmacology and Experimental Therapeutics, 1985
Amiloride, a potassium-sparing diuretic, inhibits Na+ transport, Na+-H+ exchange and possibly Na+-Ca++ exchange in a variety of cellular and epithelial tissues.

A Machine Learning Technique Regularization of the Inverse Problem in Cardiac Electrophysiology

2013
Radio-frequency ablation is one of the most efficient treatments of atrial fibrillation. The idea behind it is to stop the propagation of ectopic beats coming from the pulmonary vein and the abnormal conduction pathways. Medical doctors need to use invasive catheters to localize the position of the triggers and they have to decide where to ablate ...
