Brugada syndrome is characterized by typical electrocardiogram changes and a high risk for sudden cardiac death (Priori et al., 2013). In addition to the well known electrical substrate, morphological and functional alterations appeared to be present in a subset of the Brugada syndrome patients (Catalano et al., 2009). Echocardiographic speckle tracking enables us to detect subtle contraction alterations (Smiseth et al.,2016). We performed transthoracic echocardiography with speckle tracking analysis in 82 healthy controls and 175 Brugada syndrome patients. Main findings are presented and discussed in the article "Contraction alterations in Brugada syndrome; association with life-threatening ventricular arrhythmias" (Scheirlynck et al., 2019). This related Data article contains segmental longitudinal strain values for RV and LV, and the comparison of echocardiographic parameters between Brugada syndrome patients with spontaneous and drug-induced type 1 pattern and between patients with and without ventricular arrhythmia inducibility during electrophysiological study.
