From the Guidelines
Diltiazem (Cardizem) is not typically associated with causing tachycardia, and in fact, it is often used to treat certain types of tachycardia, such as supraventricular tachycardia (SVT) and atrial fibrillation with rapid ventricular response. As a calcium channel blocker, diltiazem works by slowing the heart rate and reducing the force of contraction, which can help to terminate or prevent tachycardia episodes 1. The 2015 ACC/AHA/HRS guideline for the management of adult patients with supraventricular tachycardia recommends the use of intravenous diltiazem or verapamil for acute treatment in hemodynamically stable patients with AVNRT 1. Some key points to consider when using diltiazem for tachycardia include:
- Diltiazem should only be used in hemodynamically stable patients, as it can worsen heart failure or exacerbate conduction disturbances in certain individuals 1.
- The drug can be effective in converting AVNRT to sinus rhythm, with success rates similar to those of adenosine and verapamil 1.
- Diltiazem may be used in conjunction with other therapies, such as vagal maneuvers or beta blockers, to enhance its effectiveness in terminating tachycardia episodes 1. Overall, the evidence suggests that diltiazem is a useful medication for treating certain types of tachycardia, rather than causing it 1.
From the Research
Cardizem (Diltiazem) and Tachycardia
- There are no research papers provided that directly discuss the relationship between Cardizem (Diltiazem) and tachycardia.
- The provided studies focus on Nicardipine, a different calcium channel antagonist, and its effects on blood pressure, angina, and other cardiovascular conditions 2, 3, 4, 5, 6.
- None of the studies mention Cardizem (Diltiazem) or its potential to cause tachycardia, making it impossible to draw a conclusion based on the available evidence.
