| [ Summary ] |
Although atrial fibrillation is the most common form of tachyarrhythmia in patients receiving maintenance hemodialysis, paroxysmal supraventricular tachycardia (PSVT) is also frequently observed. The most common form of PSVT is atrioventricular nodal reentrant tachycardia. In hemodialysis patients, PSVT is characterized by a sudden onset and termination, and the clinical symptoms are varied, ranging from mild palpitation and chest discomfort to heart failure and hemodynamic collapse. Catheter ablation is now considered the first alternative to pharmacological therapy for PSVT in both hemodialysis and nonhemodialysis patients. Pseudoventricular tachycardia is less common but requires rapid treatment, as it can result in a highly ventricular response and rarely in ventricular fibrillation. |
