WebThus, similar to calcium-channel-blocking agents, termination of tachycardia by the drug makes it likely the arrhythmia was AV node dependent but not diagnostic. Beta-blocking agents have a limited role in the acute treatment of PSVT, mainly in post-operative patients with high adrenergic states, but are still recommended in the guidelines (Class IIa, Level … Web1 nov. 2011 · Patients with recurrent episodes of SVT without pre-excitation may be treated with AV node blocking agents such as verapamil, β-receptor blockers or digoxin. These agents decrease the frequency of the episodes and the severity of symptoms in a number of patients, but complete suppression of SVT is uncommon.
