Which medication should be avoided in cases of supraventricular tachycardia (SVT)?

In cases of supraventricular tachycardia (SVT), the focus of management is often on medications that can effectively slow down the heart rate and restore normal rhythm. While Cardizem, which is a calcium channel blocker, can be used to help manage SVT, it should be used with caution due to potential side effects and the patient's hemodynamic status.

Adenosine is a first-line treatment for SVT because it can quickly interrupt the reentrant pathways and restore normal sinus rhythm. Amiodarone and Metoprolol can also be effective in managing SVT under certain circumstances, particularly for patients who have a more persistent or recurrent form of the tachycardia.

Some medications are contraindicated depending on the type and etiology of the tachycardia. In SVT cases with a wide QRS complex tachycardia or in patients with heart failure or poor ventricular function, slowing the heart rate with certain beta-blockers or calcium channel blockers may worsen hemodynamics. Thus, the recommendation against using a specific medication, such as Cardizem, stems from concerns regarding patient safety and effectiveness in specific situations.

Hence, the consideration in the management of SVT highlights why certain medications, despite their utility in
