Which one of the following drugs should be avoided in Wolff-Parkinson- White (WPW) Syndrome ?
## **Core Concept**
Wolff-Parkinson-White (WPW) Syndrome is a condition characterized by the presence of an accessory electrical pathway between the atria and ventricles, known as the Bundle of Kent. This pathway can cause the heart to beat too quickly, leading to tachycardia. The management of WPW Syndrome involves avoiding certain medications that can worsen the condition.
## **Why the Correct Answer is Right**
The correct answer, , is a medication that should be avoided in WPW Syndrome because it can accelerate conduction through the AV node, potentially increasing the heart rate and worsening the tachycardia. Atropine is an anticholinergic drug that can increase the conduction velocity through the AV node, which might be harmful in WPW Syndrome as it could potentially enhance anterograde conduction down the accessory pathway.
## **Why Each Wrong Option is Incorrect**
* **Option A:** - This option might seem plausible but is not the best choice for WPW Syndrome management.
* **Option B:** - This is not directly related to the acute management of WPW Syndrome.
* **Option C:** - This option could potentially be used in certain cases of WPW Syndrome.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl for WPW Syndrome is that **atropine and digoxin should be avoided** because they can increase the risk of accelerating conduction through the accessory pathway, potentially worsening the arrhythmia.
## **Correct Answer:** . Atropine
