Atrial fibrillation, as well as life-threatening ventricular arrhythmias.

Bradycardia (slowed heart rate).

Pulmonary fibrosis and blue-gray skin discoloration.

Abnormal levels can exacerbate arrhythmias and influence the drug's effectiveness.

These drugs are primarily renally excreted, and renal impairment can lead to drug accumulation and increased risk of side effects.

Heart rate and rhythm to ensure that the patient's heart rate isn't too low and that there's no new or exacerbating arrhythmia.

Instruct patients to monitor and report any new palpitations, dizziness, or syncope, as these could be indicators of a new or worsening arrhythmia.

Regular pulmonary function tests, liver function tests, thyroid tests, and ophthalmic exams due to potential toxicities.

Advise the patient to consult with their healthcare provider before starting or stopping any other medication, as many drugs can interact with anti-arrhythmics and influence their effectiveness or risk of side effects.
