[Puncture techniques in invasive cardiac electrophysiology].

Herzschrittmachertherapie & Elektrophysiologie, 2021
Due to good results, increasing standardization and lack of equivalent alternatives, catheter ablation has been established as an increasingly common procedure in clinical routine. This article describes common and necessary puncture techniques in catheter ablation (puncture of the groin vessels, transseptal puncture, pericardial puncture) and ...

Imaging techniques in cardiac electrophysiology

Expert Review of Cardiovascular Therapy, 2006
Modern cardiac electrophysiology procedures include catheter-based arrhythmia ablation and transvenous device implantation, which are highly dependent on accurate, real-time cardiac imaging. With the realization that anatomic structures are critical to successful electrophysiologic procedures, accurately defining a patient's cardiac anatomy has become ...

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-
