   Some drugs and medications affect heart rate, meaning you may have a lower maximum heart rate and target zone, says Dr. Steinbaum. ... It is also normal that resting heart rates go down over time ...

3. Beta blocker - Wikipedia

   en.wikipedia.org/wiki/Beta_blocker

   Beta blockers are known primarily for their reductive effect on heart rate, although this is not the only mechanism of action of importance in congestive heart failure. [17] Beta blockers, in addition to their sympatholytic β 1 activity in the heart, influence the renin–angiotensin system at the kidneys.

4. Bradycardia - Wikipedia

   en.wikipedia.org/wiki/Bradycardia

   Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.

5. Isoprenaline - Wikipedia

   en.wikipedia.org/wiki/Isoprenaline

   Isoprenaline, also known as isoproterenol and sold under the brand name Isuprel among others, is a sympathomimetic medication which is used in the treatment of acute bradycardia (slow heart rate), heart block, and rarely for asthma, among other indications. [9]

6. Antiarrhythmic agent - Wikipedia

   en.wikipedia.org/wiki/Antiarrhythmic_agent

   Class IV agents are slow non-dihydropyridine calcium channel blockers. They decrease conduction through the AV node, and shorten phase two (the plateau) of the cardiac action potential. They thus reduce the contractility of the heart, so may be inappropriate in heart failure.

   If your heart rate is slow and you feel dizzy and that you are about to pass out, it is important to see a doctor right away, says Paul Wang, M.D., director of the Stanford Cardiac Arrhythmia ...

   en.wikipedia.org/wiki/List_of_cardiology_mnemonics

   Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles). Digoxin: Helps slow the heart rate by blocking the number of electrical impulses ...

9. Ivabradine - Wikipedia

   en.wikipedia.org/wiki/Ivabradine

   Blocking this channel reduces cardiac pacemaker activity, selectively slowing the heart rate and allowing more time for blood to flow to the myocardium. [15] [16] By inhibiting the I f channel, ivabradine reduces the heart rate and workload on the heart. This is relevant in the usage of the medication to treat angina as well as congestive heart ...
