Are qRS duration and QRS fractionation on surface electrocardiogram markers of right ventricular dysfunction and atrialization in patients with Ebstein anomaly?
Delayed and prolonged depolarization of the RV is common in patients with Ebstein anomaly. The QRS duration is a marker of RV enlargement and dysfunction. QRS fractionation is associated with a greater atrialized RV volume. A preserved surface ECG identifies a subset of patients with Ebstein anomaly with mild morphological and functional abnormalities and better clinical profile.
In the study, although the level of information did not affect the quality of life, satisfaction with the information was associated with a better quality of life. The finding stresses the importance of a sensible disclosure of diagnosis and prognosis.
