Case suggests DDDR pacing may resolve symptoms in HF with chronotropic incompetence; leaves open confirmation in prospective trials.
Chronotropic incompetence is a frequent and prognostically significant condition, particularly in heart failure, that limits exercise capacity and is associated with adverse cardiovascular outcomes.
Marzlin et al. (2019) conducted a review in Chronotropic Incompetence (n=1). DDDR pacemaker was evaluated. DDDR pacemaker implantation in a 66-year-old woman with heart failure and chronotropic incompetence (maximum heart rate 70 bpm) completely resolved symptoms of fatigue and shortness of breath.
