The system utilizes a 64-pole steerable basket catheter (magnetically located) that is used to create a shell of the chamber of interest and simultaneously collect very high-density, low-noise electrogram information2.
Before the programmed stimulation examination, the intracardiac electrogram showed alternate II[degrees] I and II[degrees] II AVB.
On World Heart Day, awareness needs to be raised on this condition and that it becomes apparent only during a chance electrogram indicating damage to heart muscles.
Medical device company CardioNXT and AFTx on Wednesday jointly announced full enrolment of 65 treated patients under the Real-time electrogram Analysis for Drivers of Atrial fibRillation (RADAR) clinical trial.

Let x = {[x.sub.1], [x.sub.2], [x.sub.3], ..., [x.sub.N]} represent the electrogram time series of length N.

The intracardiac electrogram method (IEGM) has been designed to calculate optimal AV/PV and VV delays during routine device follow-up (1).
Studies have recommended RF ablation for persistent AF, since additional linear or complex fractionated atrial electrogram ablation was not possible using the CB (15,18,22).
In patients with paroxysmal AF longer than 24 hours we used exclusively RF energy and ablation procedure was completed by complex fractionated atrial electrogram and cavotricuspid istmus ablation (if common atrial flutter was confirmed before or during procedure).
Further lesions are then applied at the mapped complex fractionated electrogram (CFAE) sites.
The 2017 ADA guidelines acknowledge this and similar evidence by providing as a relatively weak Level E recommendation: "Consider screening for CAD in the presence of any of the following: atypical cardiac symptoms (e.g., unexplained dyspnea, chest discomfort); signs or symptoms of associated vascular disease including carotid bruits, transient ischemic attack, stroke, claudication, or PAD; or electrogram abnormalities (e.g., Q waves)."
