PO-04-011 FAILURE OF LEFT VENTRICLE CAPTURE MANAGEMENT ALGORITHM TO DETECT LEAD DISLODGMENT: AN UNUSUAL MECHANISM

چکیده
Automatic capture management (ACM) algorithms are extremely reliable and routinely used in cardiac resynchronization therapy devices including left ventricular (LV) leads. We report a case of failure ACM patient with biventricular (BiV) ICD unusual late dislodgement bundle branch pacing (LBBP) lead. The present highlights unique challenge patients BiV LBBP lead the port who programmed to subthreshold right (RV) outputs promote only RV fusion. A 74-year-old man nonischemic cardiomyopathy, LVEF 20% LBBB underwent successful BIV utilizing LV (Nov 2020). output was pacing. threshold stable at 1V 6-month follow-up which time had normalized. atrial During remote 1 year (Dec 2021) it noted that device stopped assessing threshold/impedance on August 2021(blue circles). Presenting rhythm demonstrated spikes without but conducted beats from sinus (AS) sensed as VF event (arrow). not attempted by due ongoing AS-BP-TF resulting tachycardia detection count 20/40. When is 3 or greater (or has actually detected an episode) will suspend lower priority functions including, limited to, impedance measurements. This detect loss occurred output, long native AV conduction outside blanking period. successfully replaced. 10 months after implant whom failed suspended higher-priority such VT detection.

متن کاملAn algorithm to predict implantable cardioverter-defibrillator lead failure.
OBJECTIVES The goal of this analysis was to test an algorithm that identifies implantable cardioverter-defibrillator (ICD) lead problems before clinical failure and/or inappropriate therapy. BACKGROUND The ICD lead failures typically present as inappropriate shock therapy. Identifying lead failures before their clinical presentation may prevent patient discomfort, improve device longevity, an...
متن کاملEight years of left ventricle pacing due to inadvertent malposition of a transvenous pacemaker lead in the left ventricle.
The inadvertent malposition of a pacemaker lead in the left ventricle is a rare and underdiagnosed pacemaker complication. A 78-year-old woman was admitted to our Emergency Department for progressive dyspnea, 8 years after transvenous pacemaker implantation. Routine 12-lead electrocardiography revealed a right bundle branch block on the paced beats, and lateral chest X-ray showed posterior defl...

Dear Editor, Splenic infarction is a rare cause of acute abdominal pain that can occur in a variety of settings including both malignant (e.g. myelofibrosis, lymphoma and leukemia) and benign hematological disorders (e.g. sickle cell hemoglobinopathies, polycythemia vera and hypercoagulable states)1. Embolic disease (e.g. atrial fibrillation, infective endocarditis, valvular disease, valve repl...
