Short-term deceleration capacity of heart rate predicts post-induction hypotension in patients with low ASA status: a prospective observational study.
Observational study in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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
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
backgroundAutonomic dysfunction is a risk factor for hypotension after anesthesia induction. Deceleration capacity of heart rate (DC) is a new method to evaluate autonomic function. This prospective observational study was designed to evaluate whether the deceleration capacity of heart rate measured by a 5-min preoperative Electrocardiogram (ECG) can reliably predict post-induction hypotension (PIH).
methodsPatients aged 18 to 65 undergoing elective surgery with lower ASA status I or II were included in this study. DC, root mean square density (RMSSD) and low frequency/high frequency ratio (LF/HF) were calculated from 5-min segments of ECG measured in the quiet state before surgery. PIH was defined as mean arterial pressure (MAP) < 65 mmHg or a decrease of > 30% for at least 1 min from induction of anesthesia to 10 min after tracheal intubation. Patients were divided into PIH and non-PIH groups according to whether they developed PIH or not.
resultsA total of 141 patients were enrolled in this study, of whom 63 (44.7%) presented with PIH. The RMSSD (p = 0.036) and DC (p < 0.001) of the PIH group were smaller, and the LF/HF was higher (p = 0.039). After adjusting for confounding factors (Model 2), DC was identified as an independent predictor of PIH (Odds Ratio: 0.377). The receiver operating characteristic (ROC) analysis showed that DC had a good diagnostic value as a predictor (AUC: 0.777; 95%CI: 0.705–0.909; p < 0.001).
conclusionsThese results suggest that DC measured by ECG 5 min before anesthesia can predict PIH to some extent in patients with ASA status I or II.
