Abstract

fetched live from OpenAlex

BACKGROUND: Premature ventricular complex (PVC) is the etiology of cardiomyopathy known as PVC-induced cardiomyopathy. Various studies have shown certain characteristics that predispose to cardiomyopathy. Present study was the first community-based study conducted to determine the characteristics and prevalence of PVC in certain population, especially Makassar City. METHODS: This study used a cross-sectional study method conducted from June 2017 to May 2018 using data from Telemedicine Electrocardiogram (ECG) at Hasanuddin University Hospital. The characteristics of PVC were QRS PVC duration, coupling interval (CI), PVC morphology in lead V1. RESULTS: We calculated 8,847 ECGs, and found 98 ECGs with PVC (1.1%). Incidence of PVC was higher in women than men (52%). Characteristics of PVC with QRS duration include < 140 ms (45.9%); 140 - 159 ms (31.6%); and > 160 ms (22.4%), respectively; and PVC with CI < 300 ms (2%), CI 300 - 599 ms (88%), and CI > 600 ms (10%). Left bundle branch block (LBBB) and right bundle branch block (RBBB) morphology were found in (76.5%) and (19.4%) subjects in turn. Statistically, QRS PVC duration and PVC morphology showed significant differences based on age group (sequentially, P = 0.012 and P = 0.014). While gender only showed a significant difference in QRS PVC duration (P = 0.030). CONCLUSIONS: The prevalence of PVC in the population of Makassar City is similar to the prevalence in other general populations. There are differences in the distribution and prevalence of PVC based on their characteristics according to age group and gender.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
