Calcium channel blockers used to treat supraventricular tachycardia include diltiazem and verapamil, states WebMD. As of 2015, diltiazem exists in forms such as Cardizem, Taztia and Tiazac, while verapamil exists as Covera-HS, Calan and Verelan. However, these medicines may result in breathing difficulty, tiredness, constipation, hives and facial inflammation. It is advisable to seek immediate medical care if side effects appear.

Beta-blockers act as a hindrance to adrenaline hormone effect in the body, leading to a reduced pulse rate, explains WebMD. Examples of beta-blockers include atenolol, propranolol, nadolol, metoprolol and acebutolol. Though usually safe, these medicines may also cause side effects such as hives, difficulty breathing, dizziness, leg inflammation and abnormally low pulse rate, which necessitate immediate medical care.

Adenosine is an anti-arrhythmic medicine that renders a quick and often short-term effect on supraventricular tachycardia patients, WebMD notes. Brands for adenosine include Adenoscan and Adenocard. Other than slowing the pulse rate, it is also applicable in diagnosing tachycardia and locating rapid pulse rate. Though helpful, adenosine may lead to headache, nausea and thoracic pressure.
