A 68 year old man known to be a chronic smoker and alcoholic has been brought to ER with chest pain and difficulty breathing for 30 min. An ECG shows irregular and wide ventricular complexes with a frequency of 160. BP is 90/60, no fever. The physician administered an iv drug and the patient becomes groggy and has convulsions.
The most likely drug that the patient received is:

I would say that the drug is Lidocaine.

What bout the ECG? Irregular wide ventricular complex?
V-tach will be regular.... not irregular...

  #3

Right jasonw it's lidocaine a quite benign iv drug considering the adverse effects. There is a problem when a patient has decreased hepatic clearance (alcoholics) and cardiac failure(VT+MI) because the drug concentration decrease is not as rapid as it is in a normal person and that might result in neurological side effects.
The VT should be regular ... sorry for the mistake.

Best for you!
