Frequency of disabling symptoms in supraventricular tachycardia

Abstract

The purposes of this study were to describe: clinical symptoms in a sample of consecutive patients with supraventricular tachycardia (SVT); incidence of sudden death, syncope, and other disabling symptoms; whether these symptoms differ by tachycardia mechanism; and to identify predictor variables of syncope in patients with SVT. Data were collected from chart reviews of 167 consecutive patients with SVT admitted for radiofrequency ablation. Three patients (2%) had nonlethal cardiac arrest, and a total of 16% (26 of 183) received at least 1 external direct-current shock for arrhythmia management. Twenty percent of subjects (33 of 167) reported at least 1 episode of syncope which was preceded by palpitations. The most frequent symptoms were: palpitations (96%), dizziness (75%), and shortness of breath (47%). We found atrioventricular nodal reentrant tachycardia (AVNRT) in 64 patients, atrioventricular-reciprocating tachycardia (AVRT) in 59, atrial tachycardia in 22, and atrial flutter in 22. The symptom profiles of patients with AVNRT, AVRT, and atrial tachycardia were very similar, but differed significantly (p <0.05) from those reported in the atrial flutter group. Multivariate analysis showed that heart rate > or = 170 beats/min was the only independent risk factor for syncope. Chi-square analysis demonstrated that SVT patients with heart rate > or = 170 beats/min had significantly more dizziness and syncope. Thus, despite a low incidence of associated heart disease, and good left ventricular function, there was a high frequency of disabling, potentially life-threatening symptoms associated with episodes of SVT in this sample. SVT can have potentially lethal consequences, and is more disruptive than previously thought.

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.
