In the Clinical image entitled “Sudden cardiac arrest in the course of mitral valve prolapse: can we prevent it?” published in the February 2025 issue (Maciejewski C, Lewandowska E, Peller M, et al. Pol Arch Intern Med. 2025; 135: 16899. doi:10.20452/pamw.16899), on page 2, there was an error in the description of Figure 1E. The phrase “resting electrocardiogram performed 4 years before sudden cardiac arrest with inverted T waves (arrows) in the lead III and acute ventricular fibrillation, biphasic in the lead II” should have read “resting electrocardiogram performed 4 years before sudden cardiac arrest with inverted T waves (arrows) in the leads III and aVF, biphasic in the lead II.”
