Wearable Patch ECG monitors and transesophageal electrophysiological study for diagnosing palpitations of unknown origin.

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
Objective: To analyze the application value of wearable adhesive Patch ECG monitors combined with transesophageal electrophysiological study (TEPS) in the diagnosis of palpitations of unknown origin. Methods: This was a retrospective study of patients with suspected arrhythmia who were admitted to Henan Provincial People's Hospital between October 2021 and July 2023 due to recurrent paroxysmal palpitations of unknown origin, with or without accompanying symptoms such as dizziness, amaurosis, and syncope. All patients underwent TEPS. Those who did not exhibit arrhythmia during the TEPS were selected for Patch ECG monitoring, which lasted several weeks (depending on the duration of symptom capture). The results of TEPS, Patch ECG monitors, and clinical diagnoses were observed and recorded. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value (NPV) for diagnosing palpitations of unknown origins was analyzed based on clinical diagnostic outcomes for (1) TEPS alone, (2) Patch ECG monitoring in patients with negative TEPS results, and (3) the combination of both methods. Results: A total of 569 patients were included in this study. The TEPS results exhibited that 227 of the 569 patients did not detect arrhythmias and 342 detected arrhythmias. Of the 569 patients, 102 refused to undergo Patch ECG monitors, and 467 patients completed the entire study process. Among them, 379 cases (66.61%) were clinically diagnosed as arrhythmias. TEPS shows good performance in most evaluation indices except NPV (69.60%, 95% CI, 61.54%-77.66%). The combined diagnosis was strongly consistent with clinical diagnosis. The accuracy, sensitivity, and NPV of TEPS combined with Patch ECG monitors in the diagnosis of palpitations of unknown origin were significantly higher than those of TEPS alone. Conclusion: Wearable adhesive patch ECG monitors combined with TEPS can enhance the diagnostic efficiency of palpitations of unknown origin.
