| Popis: | Paroxysmal supraventricular tachycardias are fast and usually regular rhythms that require some structures above the bifurcation of the His bundle to be continued, and often are caused by reentrant circuit. The 3 most common types are: atrioventricular nodal reentrant, tachycardias mediated by an accessory pathway and atrial tachycardias. They are characterized by a considerable heterogeneity of clinical presentations (ranging from almost asymptomatic forms to those producing a certain disability). They usually occur in people without structural heart disease, and their prognosis is generally benign. Differential diagnosis with other regular tachycardia with a narrow QRS complex is to be made, and electrophysiological study is sometimes necessary for an accurate diagnosis. The treatment of choice for symptomatic patients is generally catheter ablation. |
