Cardiac arrhythmia assessment with patch electrocardiogram versus insertable cardiac monitor: a cohort study in endurance athletes with atrial fibrillation.
Observational study in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04991337 (Effects of Detraining in Endurance Athletes With Atrial Fibrillation), which is not on this map. Cited by 2 papers.
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

Abstract
objectivesThe objective of this study was to assess the quality of ECG recordings and the concordance between the automatic detection of cardiac arrhythmia episodes by a patch ECG and an insertable cardiac monitor.
designProspective cohort study. SETTING AND
participantsEndurance athletes diagnosed with paroxysmal atrial fibrillation (AF) and no other relevant comorbidities participating in a randomised controlled trial on the effects of training adaption.
methodsA patch ECG (ECG247 Smart Heart Sensor) was sent to 29 non-elite endurance athletes with clinical paroxysmal AF. ECG247 continuously monitors, detects and categorises cardiac arrhythmias. The participants were simultaneously monitored with an insertable cardiac monitor (Confirm Rx, Abbott). ECG recording quality was assessed by an experienced physician. Training sessions were monitored using sports watches.
resultsOut of 29 invited athletes, 14 athletes (mean age 60.4 years, 2 women) made use of the patch ECG and were monitored for a total of 2987 hours and a median of 14 (range 1-17) days. During this period, the athletes performed a total of 112 training sessions. ECG quality varied between athletes and by type of exercise, with poor quality in 16% and 40% of recordings during cross-country skiing and running, respectively. In two athletes, the patch ECG detected AF episodes that were confirmed with insertable cardiac monitor recordings. One technical artefact was falsely classified as ventricular tachycardia by the ECG247 Smart Heart Sensor system.
conclusionMonitoring with patch ECG was feasible in endurance athletes, but ECG recording quality varied between athletes and by type of exercise.
