Abstract

The clinical, electrocardiographic and electrophysiologic determinants and effects of antiarrhythmic agents on sustained sinus node reentrant tachycardia remain poorly defined. Of 65 consecutive men undergoing electrophysiologic studies for symptomatic paroxysmal supraventricular tachycardia over a 4 year period, 11 (16.9%), who ranged in age from 39 to 76 years, demonstrated sustained sinus node reentrant tachycardia. On the surface electrocardiogram, before electrophysiologic studies, the following diagnoses were considered in the 11 patients: sinus node reentrant tachycardia on the basis of an RP'/P'R ratio of greater than 1 and P wave configuration similar to that of sinus P waves (7 patients); atrioventricular (AV) nodal reentrant tachycardia on the basis of an RP'/P'R ratio of less than 1 (3 patients); and paroxysmal atrial tachycardia with AV block (1 patient). All 11 patients had a history of recurrent palpitation, 4 had syncope, 2 had dizzy spells and 9 had organic heart disease. Sustained sinus node reentrant tachycardia could be reproducibly induced in all 11 patients during atrial pacing or premature atrial stimulation, or both, over a wide echo zone. The tachycardia could be terminated by carotid sinus massage, atrial pacing and premature atrial stimulation. Characteristics of tachycardia included: high-low activation sequence; cycle lengths of 250 to 590 ms with wide fluctuations of 20 to 180 ms in individual patients; RP'/P'R ratio of greater than 1 in 8 (73%) of the 11 patients and a ratio of less than 1 in 3 (27%). Induction of sustained sinus node reentrant tachycardia was prevented by intravenous ouabain (0.01 mg/kg body weight) in two of two patients, by intravenous verapamil (10 mg) in two of two patients and by intravenous amiodarone (5 mg/kg body weight) in four of four patients. In contrast, intravenous propranolol (0.1 mg/kg body weight) did not affect induction of sustained sinus node reentrant tachycardia in two of two patients. It is concluded that sustained sinus node reentrant tachycardia, seen in 16.9% of the study patients with paroxysmal supraventricular tachycardia, is not as benign as previously believed; it is frequently associated with organic heart disease; it demonstrates wide variations in cycle length, unlike other forms of paroxysmal supraventricular tachycardia; it can masquerade as AV nodal reentrant tachycardia and paroxysmal atrial tachycardia with AV block on the surface electrocardiogram in 36% of patients; and it is responsive to intravenous administration of ouabain, verapamil or amiodarone.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
