In the management of short-term and long-term supraventricular tachycardias (SVTs), the use of calcium channel blockers is particularly beneficial. These medications are effective at slowing down conduction through the atrioventricular (AV) node, which is crucial in controlling heart rate in patients experiencing SVTs. By reducing the heart rate and allowing for better ventricular filling, they help alleviate symptoms and improve the hemodynamics in these patients.

Calcium channel blockers can provide rapid rate control during acute episodes of SVT and are also useful for long-term management in specific cases, especially in patients with certain characteristics or comorbidities. They can help to prevent recurrences of these tachycardic episodes when used appropriately.

While beta-blockers are also utilized in managing SVTs, especially for their heart rate reduction effects and symptom control, calcium channel blockers tend to be favored in certain situations depending on the underlying rhythm and patient's overall health profile. ACE inhibitors and diuretics play different roles, primarily in heart failure or hypertension, and are not first-line treatments for controlling SVTs.
