By doing so, it helps to slow down the heart rate, decrease the force of heart contractions, and stabilize the heart rhythm.
2. Non-Selective Beta-Blocker
Betapace is classified as a non-selective beta-blocker because it acts on both beta-1 and beta-2 adrenergic receptors. Beta-1 receptors are primarily found in the heart, while beta-2 receptors are found in other organs such as the lungs, blood vessels, and skeletal muscles. The non-selective action of Betapace allows it to have a broader effect on various systems in the body.
3. Prolongs Repolarization
Another important property of Betapace is its ability to prolong the repolarization phase of the cardiac action potential. This means that it slows down the rate at which the heart’s electrical signals return to their resting state after each heartbeat. By prolonging repolarization, Betapace helps in suppressing abnormal electrical activity and preventing life-threatening arrhythmias.
4. Effects on QT Interval
The QT interval is a measure of the time it takes for the heart’s electrical system to recharge after each heartbeat. Betapace has been shown to prolong the QT interval, which is beneficial for patients with certain types of arrhythmias. However, it is important to monitor the QT interval closely during treatment with Betapace, as excessive prolongation can lead to a potentially life-threatening arrhythmia called torsades de pointes.
Research studies have indicated that the prolonged use of Betapace is associated with a small risk of torsades de pointes. However, this risk is outweighed by the significant benefits of Betapace in the treatment of ventricular arrhythmias. Regular monitoring of the QT interval and appropriate dosage adjustments are crucial to minimize the risk.
5. Additional Benefits
