Postępująca kardiomiopatia nieniedokrwienna powodująca nadczułość załamka T i nieprawidłową stymulację — opis przypadku

T-wave oversensing is one of the causes of inappropriate shocks. It results from various conditions including progressive cardiomyopathy, diminution of R-wave amplitude and relative or dynamic gain in the T-wave amplitude, electrolyte abnormalities, injury current-related increase in the T-wave voltage. We report a 59-year-old patient who presented with implantable cardioverter defibrillator shocks after 5 year implantation with decreased R-wave amplitude and T-wave changes on 12-lead electrocardiography.
