Supplementary file 1_Risk factors for different types of arrhythmias and their prognostic

A retrospective cohort study of 1,530 patients with pulmonary hypertension and left heart failure (PH-LHF) over a median follow-up of 38 months. The dataset, authored by Tian Dai and last updated in April 2026, examines the prevalence, predictors, and prognostic impact of atrial tachyarrhythmias, ventricular tachyarrhythmias, and bradyarrhythmias.

Use Cases

• Identify predictors of atrial tachyarrhythmias based on left atrial volume index (LAVI) and other clinical factors.
• Assess the association between ventricular tachyarrhythmias and right ventricular dysfunction markers like TAPSE.
• Model the differential prognostic impact of arrhythmia types on mortality and heart failure rehospitalization.
• Analyze the overlap and co-occurrence of different arrhythmia types within the patient cohort.

Strengths

• Includes 1,530 patient records, providing a substantial cohort size for analysis.
• Reports specific prevalence rates for arrhythmia types: 42.2% for atrial tachyarrhythmias, 18.0% for ventricular tachyarrhythmias, and 8.7% for bradyarrhythmias.
• Provides detailed statistical results, including odds ratios (OR) and hazard ratios (HR) with 95% confidence intervals for key predictors and outcomes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data tables is unknown, which may limit suitability assessment.
• Data is stored in a DOCX file format, which may require extraction and conversion for analysis.
