Pacemaker therapy in sino-atrial block complicated by paroxysmal tachycardia.
Pacemakers were implanted in 10 of 14 patients with dizziness and syncopal episodes of long duration, due to sino-atrial block. Paroxysmal supraventricular tachycardia, notably atrial fibrillation, had occurred in 6 patients. Medical treatment was unsatisfactory in 3 of these and pacemaker therapy was given. This abolished both syncope and paroxysmal tachycardia. Sinoatrial block and supraventr...
متن کاملRepetitive sinoatrial exit block as the major mechanism of drug-provoked long sinus or atrial pause.
Prolonged sinus or atrial pause occurred in six patients with paroxysmal supraventricular tachycardia after drug administration. All six patients had normal sinus node function during control electrophysiologic study; the sinus cycle length ranged from 510 to 900 ms (mean 743 +/- 141) and the longest sinus node recovery time ranged from 800 to 1,230 ms (mean 1,018 +/- 168). A long sinus or atri...
متن کاملFocal ablation for atrial tachycardia from the double-exit of the Marshall bundle inducing atrial fibrillation
Atrial fibrillation (AF) from the ligament/vein of Marshall (LOM/VOM) has previously been described. We report the case of a 23-year-old woman with an antiarrhythmic drug-resistant AF induced by two distinct atrial tachycardias (ATs). Focal ablation of these ATs from the double-exit of the Marshall bundle using a three-dimensional map eliminated AF triggering, even though pulmonary vein electri...
متن کاملPlasma concentration of atrial natriuretic polypeptide in patients with atrial tachycardia.
To investigate the mechanisms of polyuria associated with tachycardia, we measured plasma concentrations of alpha-human atrial natriuretic polypeptide (alpha-hANP) and cGMP in 6 patients with paroxysmal tachycardia. Plasma concentrations of immunoreactive alpha-hANP and cGMP increased by +69% (p less than 0.05) and +100% (p less than 0.05), respectively, during both paroxysmal atrial tachycardi...
متن کامل[Paroxysmal atrial tachycardia with atrio-ventricular block].
PAROXYSMAL atrial tachyeardia with atrioventricular block (PAT with block) has been recognized more often in recent years since Lown and Levine clarified its diagnostic criteria and emphasized its important relation to digitalis excess.1' 2 The present report was prompted by the increasing frequency with which this diagnosis has been made at our hospital and its common association with chronic ...
