Cardizem, or diltiazem, is a calcium channel blocker frequently used to control the rapid ventricular response associated with atrial fibrillation (Afib). It slows the heart rate by reducing the conduction of electrical impulses through the atrioventricular (AV) node.
Doctors often prescribe Cardizem intravenously (IV) as a drip for rapid rate control in patients with Afib, particularly during acute episodes. This method allows for quick and precise adjustment of the dosage to achieve the desired heart rate. Close monitoring of blood pressure and heart rate is vital during IV administration.
Oral diltiazem is also an option for long-term management of Afib’s rapid ventricular response. Your doctor will determine the appropriate dosage based on your individual needs and response to treatment. Potential side effects include dizziness, headache, nausea, and edema. Always report any concerning symptoms to your healthcare provider.
While Cardizem effectively controls the heart rate, it doesn’t treat the underlying Afib. It often works best in conjunction with other treatments, such as anticoagulants to prevent stroke, and may be part of a broader strategy including lifestyle modifications and other medications. Your cardiologist will create a personalized treatment plan.
