Tachycardia Management
Control Strategy for Atrial Fibrillation
- Lenient heart rate (HR) control, compared to strict HR control, may be beneficial in patients with persistent atrial fibrillation who have stable ventricular function (LVEF >0.40) and/or no symptoms related to atrial fibrillation
- Lenient HR control is defined as achieving resting HR <110 beats per minute (bpm); strict HR control is <80 bpm at rest and HR <110 bpm during a 6-minute walk
- May be considered as the initial HR target for rate control therapy
- Left ventricular function should be monitored in these patients
- One trial revealed that in patients with atrial fibrillation and systolic heart failure, routine strategy of rhythm control is not beneficial compared to rate control strategy
