Betaloc is commonly used for an Myocardial Bridge because beta-blockers help slow the heart rate and reduce the squeezing force of the heart, which can lessen compression of the LAD artery during systole. A dose of metoprolol 25 mg twice daily is a commonly used starting regimen, but the ?right? dose varies depending on symptoms, blood pressure, heart rate, and overall heart condition. In cases with severe systolic obliteration (such as 80%), regular follow-up with a cardiologist is important to monitor symptoms and decide whether medicines alone are sufficient or if other treatments are needed.
