Which treatment method is used for ventricular tachycardia due to bufo toxins?

Ventricular tachycardia caused by bufo toxins, particularly those derived from toads (such as the Colorado River toad), typically results from the effects these toxins have on the cardiac muscle and electrical conduction system. Lidocaine is an antiarrhythmic medication that acts by stabilizing neuronal membranes and decreasing myocardial excitability. It is particularly effective in treating ventricular arrhythmias that may arise in cases of toxicological emergencies like this.

Using lidocaine in this context helps to restore normal rhythm and suppress the abnormal electrical activity associated with ventricular tachycardia. Its rapid action makes it suitable in emergency scenarios where the heart's rhythm needs to be corrected promptly.

Other treatment options, while useful for various conditions, do not effectively target the specific issue presented by bufo toxin-induced tachycardia. Diazepam may be used for seizure control but does not address the cardiac rhythm disturbance. Atropine primarily increases heart rate by inhibiting vagal influences but is not effective in treating ventricular tachycardia. Propranolol is a beta-blocker that can slow heart rate but may not be effective in rapidly reversing life-threatening arrhythmias induced by toxic agents.

Thus, the choice of lidocaine as the treatment method is appropriate
