Final answer:
A patient with persistent tachyarrhythmia with stable hemodynamics may be managed with medications like beta blockers and antiarrhythmic agents, or with a pacemaker in chronic cases. For severe arrhythmias, cardioversion or defibrillation may be necessary.
Step-by-step explanation:
A patient with persistent tachyarrhythmia with stable hemodynamics can typically be managed with various treatments depending on the specific type of arrhythmia and underlying cause. Medications such as beta blockers or antiarrhythmic agents like procainamide are often used to help restore a normal heart rhythm. For chronic cases, medical procedures may be required, such as the insertion of a pacemaker which can regulate the heart's rhythm using electrical impulses. In life-threatening cases of arrhythmias, like ventricular fibrillation, a controlled electric shock via cardioversion or defibrillation might be necessary to restore a normal heart rhythm. It's also crucial to address the underlying causes of the arrhythmia, which could vary from stress, metabolic imbalances, thyroid issues, to more serious heart conditions.
