As in PSVT, the symptoms may include palpitations, lightheadedness, and shortness of breath. The cause of atrial fibrillation, however, may be more significant, since it may be due to agingof the conducting system of the heart and there may be associated atheroscleroticheart disease. Therefore...
CONCLUSION: Three different mechanisms of VT are encountered in patients with nonischemic CMP. The mapping and ablation approach varies with the type of VT. In this selected population, the overall efficacy was 77%.Delacretaz EStevenson WG
Electrical: These include pacemakers and defibrillators (several types including ones that can either pace, defibrillate, or even cardiovert manually ) and automatic external defibrillators (AEDs) that are available to the public, and function with external sources of electricity. Ablation: This tech...
and post-traumatic stress disorder, illustrate the algorithm; for them, literature reviews show that no single combination of altered cell-types accounts for all cases; but they identify, for each condition, which combination occurs most frequently, i.e., dominates, as compared with other possible...
Left posterior fascicular block: a new endpoint of ablation for verapamil-sensitive idiopathic ventricular tachycardia Background Verapamil-sensitive, idiopathic left ventricular tachycardia (ILVT) with right bundle branch block configuration and left-axis deviation is know......
Genetic approaches for cell-selective activation, ablation, cAMP imaging, gene knockout, and gene rescue revealed a specific area postrema neuron type that mediates behavioral responses to multiple nausea-inducing stimuli. This cell type expresses a rich assortment of cell-surface receptors, and ...
Introduction: Ventricular tachycardia (VT) with involvement of the His-Purkinje system (HPS) can be difficult to recognize in patients with heart disease, but it may be particularly susceptible to ablation targeting the HPS. This study defines the incidence and types of HPS involvement in VT....
Electroanatomical mapping of the left ventricle revealed relatively small low voltage area in the left ventricular outflow tract and identified both an arrhythmogenic focus as well as critical isthmus for reentrant VT. Radiofrequency catheter ablation successfully abolished both VTs. After the procedure,...
Radiofrequency catheter ablation(RFCA)were performed in 142 patients with paroxysmal supraventricular reentranltechycardia(PSVT),including 67 patients of left side accessory pathway,20 patients of right side accessory pathway,48 patients with slow-fast type atrioventricular nodal reentrent tachyardia(...
Genetic ablation of GPNMB did not affect acute seizures but worsened chronic epileptogenesis. We found that GPNMB functioned in phagocytosis, deficiency of which resulted in defects in both phagocytic engulfment and degradation. GPNMB could be internalized into cells, where it wrapped engulfed ...
