Analysis of Dyssynchrony and Ventricular Function in Right Univentricular Stimulation

A cross-sectional study of 40 outpatients with right ventricular pacemaker stimulation and preserved left ventricular ejection fraction. The research compares pacemaker-induced dyssynchrony among apical, medial septum, and free wall lead positions using echocardiogram and chest X-ray data. The study was authored by Ana Paula Susin Osório and is available via Open Access.

Use Cases

• Comparing interventricular conduction delay based on lead position, as measured by echocardiogram.
• Analyzing the correlation between QRS width and pre-aortic ejection time in paced patients.
• Evaluating dyssynchrony according to CARE-HF criteria across different pacing sites.

Strengths

• Includes data from 40 patients with detailed pacing site classification.
• Reports specific clinical measurements, including mean QRS time of 148.97±15.52 milliseconds.
• Uses established CARE-HF criteria for dyssynchrony assessment.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The sample size of 40 patients may limit statistical power for some comparisons.
