Internal Cardioversion of Atrial Fibrillation | Circulation
1997年10月21日 · Defibrillation electrodes were positioned in the right atrial appendage (RAap), distal coronary sinus (DCS), proximal coronary sinus (CSos), main/left pulmonary artery junction (PA), and right ventricular apex (RV). Single-capacitor biphasic waveforms (3/1 ms) were delivered through combinations of these electrodes.
Impact of Defibrillator Electrode Placement on Outcome of …
2024年6月27日 · Anterior–posterior electrode placement is preferred in electrical cardioversion of atrial fibrillation. However, the optimal anterior–posterior electrode position in relation to the heart is not studied. We performed a prospective observational study on patients presenting for cardioversion of atrial fibrillation.
Conceptual intra-cardiac electrode configurations that facilitate ...
2019年4月4日 · The proposed electrode configurations may facilitate targeted farfield anti-tachycardia pacing and/or defibrillation, which may be useful in cases where conventional anti-tachycardia pacing fails. In addition, the conceptual electrode designs intrinsically confine the electric field to the immediate vicinity of the electrodes, and may thus ...
INTRACARDIAC ATRIAL DEFIBRILLATION - PMC - National …
Studies in human patients have confirmed that additional shocking electrodes and sequential defibrillation pulses lower ADFTs. In 14 patients defibrillation electrodes were implanted in the RAA, distal coronary sinus (dCS), proximal coronary sinus (CSos), and the …
Internal Atrial and Ventricular Defibrillation During Electrophysiology ...
Internal deflbrillation is used for treating persistent atrial fibrillation and refractory ventricular arrhythmias. Atrial defibrillation can be performed with several electrode configurations but generally shocks from 1 to 50 joules are delivered between electrodes placed in the coronary sinus and lateral wall of the right atrium.
Automatic Internal Cardiac Defibrillator - StatPearls - NCBI Bookshelf
2023年5月22日 · The automated internal cardiac defibrillator or shock box is the common name given to the Implantable Cardioverter Defibrillator (ICD). ICD is a state-of-the-art device that treats arrhythmias specifically those of ventricular origin like ventricular tachycardia and fibrillation.
Alternative locations for internal defibrillator electrodes
Internal cardiac defibrillation has been successful with single or multiple endocardial electrodes, epicardial patch electrodes, and subcutaneous surface electrodes (patch, array) in varying combinations and recently with an active can electrode.
Electric fields in the heart in internal defibrillation | IEEE ...
The automatic implantable defibrillator delivers a shock directly to the heart. Optimal strategies for delivering these shocks were determined by studying a three-dimensional computer model of the electric fields produced by internal defibrillation electrodes.
Internal atrial and ventricular defibrillation during ... - PubMed
Internal deflbrillation is used for treating persistent atrial fibrillation and refractory ventricular arrhythmias. Atrial defibrillation can be performed with several electrode configurations but generally shocks from 1 to 50 joules are delivered between electrodes placed in the coronary sinus and lateral wall of the right atrium.
Internal defibrillation with minimal skeletal muscle ... - PubMed
In an effort to develop a painless defibrillation system, we designed an electrode arrangement that incorporates a conductive sock placed around the heart to confine the electric shock field to cardiac tissue.
