Refractory Supraventricular Tachyeardias
نویسندگان
چکیده
This essay is designed to review some of the basic and more recent contributions to our understanding of supraventricular tachyarrhythmias, their mechanisms, pertinent points in diagnosis, and treatment. Supraventricular tachycardia is discussed under the concept of reentrant mechanisms versus accelerated ectopic pacemakers. Atrial fibrillation and flutter, multifocal atrial tachycardia, supraventricular tachyarrhythmias associated with brady-tachy syndrome, and supraventricular tachyeardias in ventricular preexcitation are likewise discussed. An outline of the different forms of therapy for refractory supraventricular tachyarrhythmias is provided.

yENTRICUIAR and supraventricular tachyeardias are occasionally resistant to drug therapy and may culminate in congestive heart failure, circulatory collapse, ventricular fibrillation, and death. In this paper are presented recent experiences with eight patients in whom tachyeardias were unresponsive to drug therapy and were terminated by external electric countershock, usually unider general an...

متن کاملUnusual Examples of Supraventricular Re-entrant Tachyeardias
Programmed electrical stimulation of the heart uncovered unusual findings in four patients suffering from supraventricular tachyeardias. They included 1) two supraventricular tachyeardias of different location and frequency in the same patient, 2) increase in rate of a re-entrant atrioventricular (A-V) nodal tachycardia followed by the development of 2-to-1 A-V block, 3) a "gap" in A-V conducti...
متن کاملTreatment of Supraventricular Tachyeardias
In 10 patients, 24 episodes of supraventricular tachycardia were treated by rapid electrical stimulation of the right atrium. One episode of sinus tachycardia, eight episodes of atrial tachycardia, two episodes of atrial flutter, and 13 episodes of A-V junctional tachycardia occurred. In each case the diagnosis of the arrhythmia was documented by obtaining unipolar and bipolar intra-atrial elec...
