Final answer:
The antiarrhythmic drugs for treating tachycardia with a pulse according to AHA ACLS protocols include procainamide, amiodarone, and sotalol, making the correct answer 'A, B, and C'. Procainamide and amiodarone are potassium channel blockers affecting the repolarization phase of cardiac action potentials.
Step-by-step explanation:
The antiarrhythmic infusion drugs used to treat tachycardia with a pulse in Advanced Cardiac Life Support (ACLS) guidelines by the American Heart Association (AHA) include procainamide, amiodarone, and sotalol. Therefore, according to the AHA protocols, the correct answer for the given options would be (e) A, B, and C. It is important to note that procainamide and amiodarone both act as potassium channel blockers and can be used to treat cardiac dysrhythmias by affecting the movement of K+ through voltage-gated K+ channels, particularly influencing the repolarization phase of the action potential.
Beta blockers are another class of antiarrhythmic agents used for treating cardiovascular diseases and arrhythmias by blocking the sympathetic ß-receptors, thereby reducing heart rate and cardiac output. However, they are not typically mentioned as part of the AHA ACLS antiarrhythmic infusion for tachycardia with a pulse, and are not listed among the given options.
