AV nodal reciprocating tachycardia; Wolff-Parkinson-White syndrome & similar conditions w/ accessory pathway & anterograde or retrograde conduction. Paroxysmal atrial fibrillation in patients w/ disabling symptoms. Symptomatic sustained ventricular tachycardia. Premature ventricular contractions &/or non-sustained ventricular tachycardia which are causing disabling symptoms, where these are resistant to other therapy or when other treatment has not been tolerated. Maintenance of normal rhythm following conversion by other means.
View Tambocor overdosage for action to be taken in the event of an overdose.
Administration
May be taken with or without food.
Contraindications
Cardiac failure, patient w/ history of MI who has either asymptomatic ventricular ectopics or asymptomatic non-sustained ventricular tachycardia. Long-standing atrial fibrillation w/ no attempt to convert to sinus rhythm, haemodynamically significant valvular heart disease. Sinus nodal dysfunction, atrial conduction defects, 2nd degree or greater AV block, bundle branch block or distal block.
Correct electrolyte disturbances before treatment. Monitor plasma levels in patients w/ hepatic impairment. May increase endocardial pacing thresholds. Patients w/ permanent pacemakers or temporary pacing electrodes & should not be administered to patients w/ existing poor thresholds or non-programmable pacemakers.
