Leadless Pacemaker Study: P-wave Parameters and Atrioventricular Synchrony

85 patients with leadless pacemakers were studied to correlate preoperative P-wave parameters with atrioventricular synchrony. The data, published under CC-BY-4.0 on figshare, includes demographic, electrocardiogram, echocardiography, and programmable parameters from follow-ups at 1 and 3 months post-implantation. Results indicate higher P-wave area and lower P-wave dispersion predict better atrial-synchronized ventricular pacing.

Use Cases

• Predicting atrioventricular synchrony success based on preoperative P-wave area and dispersion.
• Analyzing temporal changes in atrial-synchronized ventricular pacing percentage between 1-month and 3-month follow-ups.
• Building logistic regression models to identify independent predictors of high AsVP from clinical and ECG parameters.
• Studying patient suitability for VDD leadless pacemaker implantation using demographic and comorbidity data.

Strengths

• Includes data from 85 patients with an average age of 69.1 years, providing a specific clinical cohort.
• Contains multi-timepoint follow-up data at 1 month and 3 months post-implantation.
• Combines multiple data types: demographic, ECG, echocardiography, and device programmable parameters.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is contained in a 25.9 KB DOCX file, suggesting limited raw data or a primary focus on textual results.
