Biventricular pacing is an efficient treatment to improve symptoms and clinical outcome in patients with drug-refractory heart failure, low left ventricular ejection fraction and wide QRS. The basis of the treatment is the permanent delivery of biventricular pacing. During the follow-up of biventricular devices the assessment of permanent biventricular capture is fundamental. This requires a tailored programming with respect to the patient's activity and age, and thus also careful evaluations during an exercise test as well as adequate programming in case of cardiac arrhythmias.
Key Words: Cardiac resynchronization therapy, Heart failure, Exercise test
