Adenosine depresses conduction at the atrioventricular node and is used to restore NSR (normal sinus rhythm) in patients with paroxysmal supraventricular tachycardia. Adenosine is used to treat supraventricular tachycardias, including those caused by the use of alternate conduction pathways in adults. Lidocaine is used to treat life-threatening ventricular arrhythmias during myocardial infarction or cardiac surgery; it is also used as a bolus injection in emergencies when monitoring is not available to document exact arrhythmia. Flecainide is used to treat life-threatening ventricular arrhythmias in adults; prevention of paroxysmal atrial tachycardia (PAT) in symptomatic patients with no structural heart defect. Dronedarone is used to treat paroxysmal or persistent atrial fibrillation or atrial flutter in patients with multiple risk factors for coronary artery disease who are currently in sinus rhythm or scheduled for conversion.

Feedback:
Somatropin is contraindicated in the presence of closed epiphyses so the drug can be given at any time before closure of the epiphyses. Age and height are not an indication impacting when the drug is given so long as the epiphyses remain open.
