Supraventricular tachycardia. ECG diagnosis and anatomy.
This paper reviews the anatomical substrates responsible for the induction and maintenance of supraventricular tachycardia and discusses the ECG findings associated with these tachycardias. The normal anatomy of the supraventricular conducting system, particularly within the atria, is complex with conduction proceeding along preferential pathway, which are in turn determined in part by the anis...
متن کاملRapidly Recurring Supraventricular Tachycardia
or digitalis and quinidine, prevented tachyeardia in five patients and slowed it in one. Our cases suggest the following: (1) Recurrent supraventricular tachycardia in patients without the WPW syndrome may frequently be caused by a reciprocal mechanism. (2) The diagnosis of reciprocating tachycardia should be suspected when (a) the tachycardia recurs within minutes of its termination, (b) the o...
متن کاملSupraventricular tachycardia initiated by sinus beats.
In the present report, A-V dissociation with concealed retrograde conduction into the A-V node, caused SINUS beats to exhibit antegrade A-V nodal conduction delay sufficient to result in episodes of supraventricular tachycardia (SVT). In this patient, atrial ectopic premature depolarizations were never observed. The primary role of A-V nodal conduction delay in the genesis of paroxysmal SVT is ...
متن کاملTermination of supraventricular tachycardia by propofol.
It is known that propofol can have effects on atrioventricular node conduction. We report a case where administration of propofol was associated with termination of supraventricular tachycardia. Although a similar phenomenon has been reported in children, this is the first such case in an adult.
متن کاملSyncope and supraventricular tachycardia.
A41-year-old man was referred for electrophysiological evaluation after recurrent syncope that occurred frequently during vigorous exercise. The patient had a complete, normal cardiological work up, including a resting ECG, an exercise stress test, and an echocardiogram. He reported that just before loss of consciousness, his heart was beating very fast. An electrophysiological study was perfor...
