May support nadolol preference in adrenergic non-ischaemic ventricular arrhythmias; leaves open need for randomized confirmation.
Do propranolol and nadolol improve arrhythmia control in patients with non-ischaemic ventricular arrhythmias based on sympathetic drive?
Beta-blockers, particularly nadolol, are effective in controlling non-ischaemic ventricular arrhythmias in patients with high sympathetic drive, but not in those with non-adrenergic characteristics.
Coumel et al. (1982) studied this question.
