What are some common adverse effects of Adenosine?

Adenosine is often used in the treatment of specific types of supraventricular tachycardia due to its effects on the heart's conduction system. One of the notable adverse effects of adenosine administration is transient asystole, which can occur as the drug temporarily affects the heart's rhythm while it decreases conduction through the atrioventricular (AV) node. Patients may also experience shortness of breath, which is another common side effect linked to adenosine, stemming from the rapid changes in heart rate and the body's response to the drug.

Transient asystole is typically brief and resolves quickly as the drug’s effects are short-lived, and shortness of breath may be related to the physiological changes and anxiety that accompany rapid heart rate changes.

Other listed adverse effects, such as persistent cough and nausea, severe headache and vertigo, or hypotension and bradycardia, are not commonly associated with adenosine usage. This context helps to solidify why options involving transient asystole and shortness of breath are correct, reflecting the specific pharmacological effects of adenosine on the cardiovascular system.
