Under the guidance of the three-dimensional atrial geometry (CARTO System, Biosense Webster), endocardial activation mapping demonstrated that the earliest endocardial activation site was in the RAA where the local electrogram was 90 ms prior to the onset of the a wave on reference CS[sub]5-6[Figure 1].
If the patient presented in atrial fibrillation, complex fractional atrial electrograms are also mapped during the anatomical mapping of the left atrium.
Study of unipolar electrogram morphology in a computer model of atrial fibrillation.
in MADIT, nearly 60% of patients received an ICD shock within two years of ICD implantation but the appropriateness of these shocks could not be assessed due to limitations in electrogram storing capabilities in this generation of devices.
These devices can deliver critical high-quality information, such as temperature, mechanical force, blood flow and electrogram, to the surgeon in real time.
The topics are: from generator to pulmonary vein isolation, fluoroscopic anatomy of the left atrium, PVAC management in practice, the electrode and the electrogram, assessing pulmonary vein isolation using the PVAC and the coronary sinus catheter, differential pacing beyond the coronary sinus to validate isolation of the pulmonary vein, additional maneuvers to ensure pulmonary vein isolation, and unusual tracings during ablation using the PVAC.
Hazardous incidents included: ventilation rate changes and total switch-offs of mechanical ventilators; complete stoppage of syringe pumps; external pacemaker malfunctions; complete stoppage of renal replacement devices; and, electrocardiogram interference in atrial and ventricular electrogram curves read by the pacemaker programmer.
Moreover, segments 5 and 7 of isolate 02VN178b and segments 8 and 11 of isolate 02VN009b showed a mixed electrogram pattern of clusters V and IV or III.
For each ICD-recorded episode of tachyarrhythmia, the date, time, beat-to-beat intervals, and intracardiac electrogram before, during, and after episodes were recovered from the ICD.
