Final answer:
In treating cardiac arrhythmias, normal heart rate and rhythm are restored through medications, medical procedures, or surgery, considering individual factors like electrolyte balance and intravascular volume.
Step-by-step explanation:
Cardiac arrhythmias are abnormal heart rhythms that may manifest as bradycardia (slow heart rate) or tachycardia (fast heart rate). Treatment prioritizes restoring normal heart rate, rhythm, and blood pressure. Addressing electrolyte imbalances and ensuring adequate intravascular volume can be crucial in managing dysrhythmias.
For tachycardia, medications like beta blockers or antiarrhythmic agents such as procainamide may be used. In bradycardia cases, a pacemaker might be necessary if the condition is severe. Patients with chronic problems might maintain a junctional rhythm, where an artificial pacemaker can help restore full sinus rhythm. For acute severe symptoms or life-threatening scenarios, treatments like cardioversion or defibrillation may be employed.
