Can We Consider PR Interval to Screen Patients for Cardiac Resynchronization Therapy?

This Short Editorial is referred by the Research article "Baseline Prolonged PR Interval and Outcome of Cardiac Resynchronization Therapy: A Systematic Review and Meta-analysis".
The search for response markers to Cardiac Resynchronization Therapy (CRT) remains intensive. Currently, the main criteria for CRT indication are the QRS morphology and the absence of myocardial fibrosis.
The electrocardiogram remains an important tool for selecting CRT candidates, and new parameters, such as the PR interval, are interesting to discriminate the prognosis in this population. On this issue, we have a meta-analysis study concluding that the presence of prolonged PR interval is a marker of poor prognosis at baseline.
