Not completely safe: The trigger for svt needs to be determined. Stress ; holter. Metoprolol comes in 3x/day ; once daily forms. Daily form at doses of 12.5-25 mgs unlikely to lower BP in a young hydrated person and may control svt. Diltiazem er has some blood pressure lowering properties but is a good choice for svt. Diltiazem sa 120mgs is anti-inotropic, but this is a low dose. Both but may reduce endurance mildly.
