Which of the following is NOT an indication for Verapamil?

Verapamil is a calcium channel blocker primarily used in the management of cardiovascular conditions. It is indicated for various arrhythmias, particularly supraventricular tachycardia (SVT) or paroxysmal supraventricular tachycardia (PSVT) that does not respond to Adenosine, as it helps to slow down the conduction through the AV node and restore normal rhythm. Additionally, Verapamil is effective in treating hypertension by causing vasodilation and reducing peripheral vascular resistance, and it can also relieve angina by reducing myocardial oxygen demand and improving oxygen delivery, especially in cases of vasospastic or unstable angina.

However, the use of Verapamil in heart failure is generally contraindicated. It can lead to a decrease in cardiac contractility and may exacerbate the condition in patients with compromised left ventricular function. Therefore, heart failure is not an appropriate indication for Verapamil, making it the correct answer in this case.
