Long Term Management of Arrhythmias

Question 1

Long-term Management of Symptomatic Nonsustained VT Initial Therapy

Answer 1

β-Blockers may be considered for a therapeutic trial in symptomatic patients
Non-dihydropyridine CCBs may be considered as an alternative

Question 2

Long-term Management of Symptomatic Nonsustained VT Secondary Therapy

Answer 2

AAD therapy (amiodarone, flecainide, mexiletine, propafenone, sotalol) may be considered to
improve symptoms associated with arrhythmias in patients receiving adequate doses of a β-blocker
or CCB

Question 3

β-Blockers use with ICD

Answer 3

Considered mainstay therapy
Effective in suppressing ventricular ectopic beats and in reducing SCD in a spectrum of cardiac
disorders in patients with and without HF (nonsustained VT)

Question 4

Amiodarone use with ICD

Answer 4

Can be used in combination with β-blockers to decrease firing of IC; Increases threshold

Question 5

Sotalol use with ICD

Answer 5

Can suppress VT and be used to decrease frequency of ICD firing; decreases threshold
