Invasive Cardiac Electrophysiology in the Mouse Techniques and Applications

Trends in Cardiovascular Medicine, 2000
As the genetic nature of a wide spectrum of cardiovascular diseases is being elucidated, it is increasingly important to understand the functional role of specific genes on cardiac arrhythmia and conduction disturbances. The progress made in molecular genetics has allowed the creation of mice with targeted gene overexpression or elimination.

Translation of Tools and Techniques from the Adult Electrophysiology World to Pediatric Cardiac Implantable Electronic Devices

Cardiac Electrophysiology Clinics, 2023
This article reviews various opportunities to translate established and novel tools and techniques used in adult electrophysiology to pediatrics and the adult congenital heart disease population. There is a specific focus on preoperative management of special population, implantation techniques, and postoperative programming of devices.

Specialized Cardiac Conduction System

Archives of Surgery, 1970
An electrophysiologic technique has been described to localize the atrioventricular (A-V) conduction system during cardiac surgery. The method utilizes atrial pacing with an electrode plaque to insure a supraventricular rhythm, and an electrode probe to localize the specialized A-V pathways.

Cardiac Conduction System: Anatomic Landmarks Relevant to Interventional Electrophysiologic Techniques Demonstrated with 64-Detector CT

RadioGraphics, 2007
The rapid development of clinical cardiac electrophysiology has triggered a renewed interest in the anatomy of the heart. A thorough knowledge of cardiac anatomy is a prerequisite for successful electrophysiologic procedures. Accurate description of the cardiac anatomy requires the use of a common language in describing this anatomy, as well as close ...

A portable stimulation system suitable for the development of new techniques in cardiac electrophysiological studies

Proceedings of the 1998 Second IEEE International Caracas Conference on Devices, Circuits and Systems. ICCDCS 98. On the 70th Anniversary of the MOSFET and 50th of the BJT. (Cat. No.98TH8350), 2002
A cardiac electrophysiological study (EPS) is a clinical procedure of supreme utility for the diagnosis of the causes of bradycardia and tachycardia. At present, research is been carried out on a minimally invasive approach of this procedure. Therefore, the authors have developed a modular system between a portable PC and the patient, which is suitable

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 ...

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 ...
