Abstract Background: Recent studies suggest that baseline prolonged PR interval is associated with worse outcome in cardiac resynchronization therapy (CRT). However, a systematic review and meta-analy
Abstract Background: Cardiac cachexia is an important predictive factor of the reduction in survival of patients with heart failure with reduced ejection fraction. Objectives: The aims of the present
BackgroundThe optimal pacing rate during cardiac resynchronization therapy (CRT) is unknown. Therefore, we investigated the impact of changing basal pacing frequencies on autonomic nerve function, car
Despite the major advances in medical drug therapy, heart failure remains a syndrome associated with high mortality and morbidity. Biventricular or left ventricular (LV) short atrioventricular (AV) de
The following data were collected at the first medical visit and during follow-up (1) echocardiography parameters, including left ventricular ejection fraction (LVEF), left ventricular end-diastolic v
