Beta Blockers Will Lower Your Heart Rate
The meaning of BETA-BLOCKER is any of a class of drugs (such as propranolol) that decrease the rate and force of heart contractions and lower high blood pressure by blocking the activity of beta-receptors.
Medications may not work right away. Beta blockers are often prescribed in pill form and can take one to two hours to cause physical effects. In some cases, these medications are taken on a schedule to consistently prevent adrenaline production, maintain a low heart rate, and maintain a “ca...
To explore the effect of beta-adrenergic blockade on low heart rate-related (mental stress) ischemia, 19 patients with coronary artery disease were randomized into a double-blind crossover trial of metoprolol, 100 mg twice daily, and underwent serial mental stress/bicycle exercise studies. Mental ...
abeta blocker; beta-adrenergic inhibitor that slows heart rate and decreases cardiac contractility and cardiac output, thereby lowering blood pressure; beta blockers are less effective in African Americans than they are in Caucasians; the same is true for angiotensin-converting enzyme (ACE) inhibitors...

The beta blockers are a benefit due to the reduction of the heart rate which will lower the myocardial energy expenditure. This is turns prolongs the diastolic filling and lengthens coronary perfusion.[9]Beta blockers have also been a benefit to improving the ejection fraction of the heart desp...
