Physical Activity Levels and Quality of Life in Outpatients with Cardiac Arrhythmias and Preserved Left Ventricular Function: Understanding Their Profile.
Article in Arquivos brasileiros de cardiologia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cardiac arrhythmias are heterogeneous conditions that may limit physical activity (PA) and impair quality of life (QoL). To describe levels of PA and perceived barriers as well as to assess their associations with arrhythmia phenotype and QoL in tertiary care outpatients with preserved left ventricular (LV) function. This pilot cross-sectional study enrolled adults with documented arrhythmias and LV ejection fraction (LVEF) ≥ 50%. PA was assessed using the International Physical Activity Questionnaire (IPAQ) short form, and QoL using the 12- Item Short Form Survey (SF-12). Arrhythmias were classified as supraventricular tachycardia (SVT), atrial fibrillation (AF) and/or atrial tachycardia (AT) (including atrial flutter when applicable), ventricular, inherited, or multiple. Associations were analyzed using chi-square tests, multinomial regression, and linear regression models. Among 202 participants (mean age 50.5 ± 15.3 years; 58.9% men), 20.3% were sedentary and 45.6% were active or very active. The prevalence of sedentary behavior was higher among patients with ventricular arrhythmias (25.9%), inherited arrhythmias (35.1%), and multiple arrhythmias (25.0%) compared with those with SVT (3.8%) and AF/AT (8.0%) (p = 0.043). In adjusted models, active or very active PA showed a trend toward higher SF-12 physical component scores (p = 0.08), whereas mental component scores were primarily influenced by symptom status and sex. In this tertiary outpatient cohort with arrhythmias and preserved LVEF, physical inactivity clustered among higher-risk phenotypes and was frequently associated with potentially modifiable barriers, including medical advice and lack of time. Higher levels of PA tended to be associated with better physical health status, supporting individualized, risk-based counseling and supervised strategies to safely promote PA in patients with arrhythmias.
