Intravenous diltiazem, verapamil, or metoprolol can be useful in terminating hemodynamically stable regular SVT of uncertain type (moderate-quality evidence for diltiazem and verapamil and low-quality evidence for -blockers), multifocal atrial tachycardia (low-quality evidence for metoprolol and verapamil and none for diltiazem
For patients with more robust hemodynamics and lower risk of hypotension, either a beta-blocker or diltiazem may be chosen (more on this below). beta-blocker (usually metoprolol) vs. diltiazem? One of the longstanding controversies in AF management has always been selecting between metoprolol and diltiazem.
Avoid Diltiazem with Metoprolol (risk of AV Block) If already on a rate control agent (e.g. Metoprolol or Diltiazem) when presented with RVR.

by JL Martindale Cited by 42(n=92) comparing IV diltiazem with IV metoprolol. The combined relative risk of acute rate control by diltiazem versus metoprolol was 1.8 (95% CI 1.2-2.6).

The articles reviewed comparing intravenous diltiazem and metoprolol for the acute treatment of AF with RVR suggest diltiazem may be more
diltiazem vs metoprolol for acute AF. However, patients with diltiazem had higher incidence of worsening CHF symptoms defined as increased
