Q
  1. How can ventricular rate be controlled in AF?

2. If this does not work, what can be used?

A
  1. Monotherapy:

Standard beta blocker (not sotalol)
Rate limiting CCB e.g. verapamil
Diltiazem is used but unlicensed
Digoxin

  1. Combination of beta blocker, digoxin or diltiazem

Q

What group of patients should digoxin monotherapy be used for ventricular control in AF?

A

Only effective for controlling the ventricular rate at rest, so should only be used as monotherapy in sednetary (inactive) patients with non-paroxysmal atrial fibrillation.

Q

When would dronedarone be used in rhythm control for AF?

A

As an option for the maintenance of sinus rhythm after successful cardioversion in people with paroxysmal or persistent atrial fibrillation:

  • whose atrial fibrillation is not controlled by first‑line therapy (usually including beta‑blockers), that is, as a second‑line treatment option and after alternative options have been considered and who have at least 1 of the following cardiovascular risk factors:
  • hypertension requiring drugs of at least 2 different classes
  • diabetes mellitus
  • previous transient ischaemic attack, stroke or systemic embolism
  • left atrial diameter of 50 mm or greater or
  • age 70 years or older and

And:
who do not have left ventricular systolic dysfunction and
who do not have a history of, or current, heart failure.
(consider amiodarone in these patients)

Q

What are the key side effects of amiodarone?

A
  1. Corneal microdeposits (reversible upon withdrawal of treatment but can cause blindness)
  2. Thyroid function- amiodarone contains iodine and can cause hyper and hypothyroidism (thyrotoxicosis)
  3. Hepatotoxicity
  4. Pulmonary toxicity- pneumonitis should always be suspected is new or worsening SOB occurs
  5. “Dazzled in light” phototoxicity
  6. Grey skin discolouration
  7. Altered taste
  8. Sleep disorders

Q

What is the patient advice regarding amiodarone and the sun?

A

Patients should be instructed to avoid exposure to sun and to use protective measures during therapy as patients taking Amiodarone tablets can become unduly sensitive to sunlight, which may persist after several months of discontinuation of Amiodarone tablets. In most cases symptoms are limited to tingling, burning and erythema of sun-exposed skin but severe phototoxic reactions with blistering may be seen.

Patients need to shield their skin from light during treatment and for several months after discontinuing treatment as it has a very long half life

Q

What is the important safety information regarding sotalol and what it should be used for?

Need to correct any hypokalaemia before starting

The use of sotalol should be limited to the treatment of ventricular arrhythmias or
prophylaxis of supraventricular arrhythmias. It should no longer be used for angina, hypertension,
thyrotoxicosis or for secondary prevention after myocardial infaction
