  2. Bradycardia - Wikipedia

    en.wikipedia.org/wiki/Bradycardia

    The term "relative bradycardia" can refer to a heart rate lower than expected in a particular disease state, often a febrile illness. [8] Chronotropic incompetence (CI) refers to an inadequate rise in heart rate during periods of increased demand, often due to exercise, and is an important sign of SND and an indication for pacemaker implantation.

  3. Beta-adrenergic agonist - Wikipedia

    en.wikipedia.org/wiki/Beta-adrenergic_agonist

    Increased heart rate and heart muscle contraction are associated with the β1 receptors; however, β 2 cause vasodilation in the myocardium. [citation needed] β3 receptors are mainly located in adipose tissue. [5] Activation of the β 3 receptors induces the metabolism of lipids. [6]

  4. Sympathomimetic drug - Wikipedia

    en.wikipedia.org/wiki/Sympathomimetic_drug

    Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines) are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. Examples of sympathomimetic effects include increases in heart rate , force of cardiac contraction , and blood pressure . [ 1 ]

  5. Chronotropic - Wikipedia

    en.wikipedia.org/wiki/Chronotropic

    Chronotropic effects (from chrono-, meaning time, and tropos, "a turn") are those that change the heart rate. Chronotropic drugs may change the heart rate and rhythm by affecting the electrical conduction system of the heart and the nerves that influence it, such as by changing the rhythm produced by the sinoatrial node. Positive chronotropes ...

  6. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    Heart rate recovery (HRR) is the reduction in heart rate at peak exercise and the rate as measured after a cool-down period of fixed duration. [56] A greater reduction in heart rate after exercise during the reference period is associated with a higher level of cardiac fitness. [57]

    A wealth of recent research, including a new study published this month in the Journal of Alzheimer's Disease, suggests that any type of exercise that raises your heart rate and gets you moving ...

  8. Athletic heart syndrome - Wikipedia

    en.wikipedia.org/wiki/Athletic_heart_syndrome

    The heart becomes enlarged, or hypertrophic, due to intense cardiovascular workouts, creating an increase in stroke volume, an enlarged left ventricle (and right ventricle), and a decrease in resting heart rate along with irregular rhythms. The wall of the left ventricle increases in size by about 15–20% of its normal capacity.

    Exercise mimetics are a proposed class of drugs that aim to do exactly what the name suggests: mimic the health benefits of exercise. SLU-PP-332 and the new compounds fall into this category.
