WebThese drugs lower heart rate and blood pressure. Central-acting agents lower heart rate and reduce blood pressure. The medicine blocks signals from the brain to the nervous system that increase the heart rate and narrow blood vessels. As a result, the heart doesn't pump as hard and blood flows more easily through the body's veins and arteries. WebJul 14, 2016 · Glucagon activates adenylate cyclase in the myocardium, which increase cAMP production. At high enough concentrations, cAMP activates a non-adrenergic pathway that improves inotropy and chronotropy. In other words, glucagon can improve cardiac contractility and AV conduction by circumventing an existing beta blockade. …
