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.

BackgroundHuman pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) show tremendous promise for cardiac regeneration following myocardial infarction (MI), but their transplantation gives rise to transient ventricular tachycardia (VT) in large-animal MI models, representing a major hurdle to translation.

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. During early childhood, 50% of patients develop multifocal atrial tachycardia, a treatment-resistant tachyarrhythmia of unknown pathogenesis. HCN inhibitors targeted pacemaker-like activity in mutant ACMs. Automated patch clamping assessed funny currents.

with one documented SP after termination of atrial tachycardia at the 3-month follow-up. Conclusion CNA may be an effective alternative to pacemaker implantation in pediatric patients with syncope or significant symptoms secondary to functional SP or AVB. Post-CNA, the median longest pause was 1.3 s s (range 0.8–2.2)

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. However, concomitant infections and pacemaker implantations occur in this cohort. Hospital stay after CA was 2.32

How does a pacemaker accomplish RBBB morphology? Quick aside on device terminology (feel free to skip): A "single chamber" pacemaker is a device with only one lead. A "dual chamber" pacemaker is a device with an atrial lead and a ventricular lead. So the most likely rhythm in ECG 1 is ectopic atrial tachycardia.

If the patient has Abnormal Vital Signs (fever, hypotension, tachycardia, or tachypnea, or hypoxemia), then these are the primary issue to address, as there is ongoing pathology which must be identified. Negative predictors included dementia, pacemaker, coronary revascularization, and cerebrovascular disease. orthostatic vitals b.
