What can be a rare side effect of Beta I stimulation?

Beta-1 stimulation primarily affects the heart, where it leads to increased heart rate and contractility. While it is generally associated with positive inotropic and chronotropic effects, a rare side effect can indeed include the development of arrhythmias. This occurs because excessive stimulation of beta-1 receptors can disrupt the normal electrical conduction pathways in the heart, leading to various types of arrhythmias such as atrial fibrillation or ventricular tachycardia.

Arrhythmias can present as a consequence of heightened adrenergic activity, especially in individuals who may have underlying heart conditions or are sensitive to beta-agonist medications. It's important to monitor patients receiving beta-adrenergic agents for signs of dysrhythmias, ensuring an appropriate and safe response to the medication.
