Typically, patients with HCM experience sinus tachycardia and sinus arrest relatively infrequently. To manage the complex comorbidities, we opted for dual-chamber pacemaker implantation. Meanwhile, a dual-chamber pacemaker can treat HCM by changing the sequence of myocardial contraction.
She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Answer : The ECG above shows a regular wide complex tachycardia. Said differently, the ECG shows a rather slow ventricular tachycardia with a 2:1 VA conduction. Cardiac output (CO) was being maintained by the tachycardia.
A patient in the ICU with significant underlying cardiac disease [HFrEF 30%, non-ischemic cardiomyopathy, LBBB s/p CRT-D (biventricular pacer), AVNRT s/p ablation a few yrs ago, hx sinus tachycardia while on max tolerated BB therapy] went into a regular wide-complex tachycardia after intubation for severe COPD exacerbation.
Conclusions This study is expected to provide valuable findings regarding arrhythmia in HFnon-rEF patients, and elucidate a potential new therapeutic approach for HFnon-rEF. Trial registration number This trial has been registered in the Japan Registry of Clinical Trials (jRCT) (Trial Registration: jRCTs052210060).
Cardioneuroablation (CNA) is a catheter-based intervention, used to identify and ablate the epicardial ganglionated plexi (GP), which results in disruption of the vagal-mediated parasympathetic input to the sinus and atrioventricular node. with one documented SP after termination of atrial tachycardia at the 3-month follow-up.
This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). If there had been — a temporary atrial pacemaker could have been considered as a way of increasing the heart rate to suppress a bradycardia-dependent arrhythmia ("overdrive pacing").
ABSTRACT Background Catheter ablation (CA) for atrial fibrillation (AF) in the elderly poses a growing challenge. Methods Octogenarians with AF or consecutive atrial tachycardia undergoing index or re-ablation (pulmonary vein isolation [PVI] and ablation beyond PVI with different energy sources) in a single center, were analyzed.
The CASE Continues: The patient had many episodes of NSVT ( Non-Sustained Ventricular Tachycardia ) — like th e one shown below in Figure-6. A permanent pacemaker was placed and the patient was atrial paced at 60bpm. After pacemaker placement — a ß-blocker was initiated. Can YOU identify atrial activity in Figure-6 ?
