A novel ECG finding in patients with epicardial infarct-associated ventricular tachycardia: a case series.

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
objectivesThis study analyzes the incidence, characteristics, and ECG morphology of ventricular tachycardia (VT) in post-infarction patients undergoing epicardial VT ablation.
backgroundAblation of recurrent VTs in patients with ischemic cardiomyopathy is typically performed endocardially. In rare cases, epicardial access is required to achieve non-inducibility. METHODS AND
resultsThe study evaluated the baseline characteristics, procedural data, and ECG morphology of clinical VT in patients undergoing epicardial VT ablation. From the initial 491 patients with coronary heart disease (CHD) and recurrent VTs undergoing ablation at the Heart Center of Leipzig, Germany, between 2012 and 2020, only 39 patients required an additional epicardial access. In 17 patients, the VTs were associated with infarction scar, while the remaining patients had concomitant CHD without infarction-associated scar and were excluded from the analysis. A propensity match study was performed at a 1:2 ratio for these 17 patients, with 34 patients of the initial cohort as a control group to evaluate the differences in baseline characteristics, procedural data, and ECG morphology of the VTs. The specific VT morphology of negative concordance and superior axis in patients with inferior scar as well as the history of VT ablation were independent predictors of the need for epicardial access.
conclusionsIn addition to previous endocardial ablation, VT ECG morphology with negative concordance and superior axis in post-infarction patients with inferior scar predicted the need for epicardial VT ablation.
