24Â h and prolonged ambulatory ECG recording in patients with ventricular ectopy: Maybe 24Â h are not enough?

Twenty-four-hour AECG underestimates the risk of ventricular arrhythmias in patients with cardiovascular risk factors or history of CHD. Prolonged AECG might reduce this underestimation, particularly among patients at low risk. A careful cost-benefit assessment needs to be held in order to identify the most convenient AECG duration and subsets of patients most benefiting from prolonged AECG.
