Impact of Pacing and High-Pass Filter Settings on Ventricular Bipolar Electrograms in Implantable Cardioverter Defibrillator Systems - Implication of Predictors for Inappropriate Therapy Caused by Oversensing of Repolarization Electrograms -

Incidence and Predictors of Pericardial Effusion After Permanent Heart Rhythm Device Implantation

“…Careful supervision should always be given when operators at the beginning of their learning curve participate in HRD implantation. 29 Moreover, an atrial active fixation lead (either at the RA appendage or at the lateral wall of the right atrium) was frequently used (86%) in patients who subsequently developed large PE with tamponade physiology. This suggests caution when screw-in leads are used in the right atrium, where the thickness of the myocardium is limited.…”

Pitfalls in electrogram interpretation: Subcutaneous cardioverter defibrillator malfunction in Brugada syndrome

“…Inappropriate S-ICD therapy, according to available literature, is mostly secondary to T-wave oversensing. 4 S-ICD lead damage has rarely been described but should be considered as possible cause of inappropriate shock. An accurate and standardized S-ICD implantation technique may avoid the risk of direct device damage.…”

Development of ventricular fibrillation after implantation of a biventricular implantable cardioverter defibrillator: what is the mechanism?

“…Maesato et al. also showed that T‐wave amplitudes in ICD recipients with Brugada syndrome were higher than those in non‐Brugada patients, regardless of high‐pass filter settings .…”
