Rate control is a widely used treatment strategy for management of patients with
atrial fibrillation (AF). Multiple studies have shown that pharmacologic rate
control is as effective as pharmacologic rhythm control for management of AF. A
snapshot ECG or intermittent monitoring using Holters is the most widely used
technique for assessing ventricular rate during AF. Patients with implantable
devices, such as pacemakers, implantable cardioverter defibrillators, cardiac
resynchronization therapy devices, and implantable loop recorders provide the
ability for continuous long term monitoring of AF and ventricular rate during AF.
It has been shown that continuous monitoring of AF and ventricular rate during AF
by implantable devices is the most comprehensive method for assessment of AF
occurrence and poor rate control, particularly in patients with paroxysmal and
asymptomatic AF. Rapid ventricular rate during AF, as assessed by implantable
devices, has been shown to cause reduction in cardiac resynchronization therapy,
predict inappropriate defibrillation therapy, and identify increased risk for
cardiovascular hospitalizations. The ventricular rate targets for achieving good
rate control during AF depend on the patient characteristics with stricter
targets recommended for patient with compromised functional capacity, such as
patients with HF. Thus it can be hypothesized that timely intervention based on
continuous assessment of AF and poor rate control, with ventricular rate targets
defined based on cardiovascular disease state, may improve clinical outcomes in
patients with AF.
