Abstract
This report examines the impact of resynchronization therapy in a patient with class IV heart failure and a prolonged QRS duration on electrocardiogram. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to assess the patient's health status prior to, immediately after, and 2 months after placement of a biventricular pacemaker. B-type natriuretic peptide (BNP) values and electrocardiogram QRS duration were recorded to further document clinical status. Our patient experienced statistically significant improvements in 7 of 10 KCCQ domains after resynchronization. QRS duration narrowed following the procedure and BNP values decreased. Resynchronization therapy improved this patient's symptoms, physical limitations, and self-efficacy when maximal medical therapy failed.
