Cardizem, or diltiazem, is a calcium channel blocker. A Cardizem bolus is a rapid intravenous administration of the drug, typically used for immediate control of rapid heart rates (tachycardia) or elevated blood pressure (hypertension).
Doctors administer a Cardizem bolus in specific situations requiring immediate action. These include:
| Supraventricular tachycardia (SVT) | Slows the heart rate by reducing electrical conductivity in the heart. |
| Hypertensive crisis | Rapidly lowers blood pressure in dangerously high situations. |
| Atrial fibrillation with rapid ventricular response | Controls the rapid heart rate associated with this irregular heart rhythm. |
| Chest pain (angina) | Can reduce chest pain by improving blood flow to the heart. (Usually alongside other treatments) |
The dosage of a Cardizem bolus varies greatly depending on the patient’s condition, medical history, and other medications. Always follow your doctor’s instructions carefully. A healthcare professional monitors the patient’s heart rate and blood pressure closely after administration to ensure the treatment is safe and effective. Side effects are possible and should be reported immediately. This information should not replace advice from your doctor or other healthcare provider.
