In the ECG shown below which drug is not to be given?

ECG shows is atrial fibrillation. Drug Use Amiodarone Amiodarone is used to prevent recurrent AF unresponsive to beta-blockers. Adenosine Adenosine can conve relatively stable atrial flutter with 2:1 conduction and a hea rate of 150 to 1:1 conduction with a hea rate of 300 and cause rapid clinical decompensation. Because of this, adenosine can be dangerous when given to patients with atrial fibrillation, especially if they have a bypass track Diltiazem Prevents a rapid ventricular rate from developing if AF is conveed to "slow" AFL with the drug therapy. Beta-blocker Used for rate control in atrial fibrillation leading to hypotension and syncope.
