Why does potassium affects the heart rate?

Expert Solution

1) Potassium plays a role in every heart beat. It helps trigger your heart to squeeze blood through your body. It also help your muscles to move, your nerves to work, and your kidneys to filter blood.

The flow of potassium in and out of heart cells helps regulate your heart beat. An above normal level of potassium can interfere with proper electric signals in that muscle layer and leads to different types of heart arrhythmias.

Having too much potassium in your blood is hyperkalemia and it can be dangerous. Too much potassium in your blood cause suppretion of electrical activity of the heart and cause irregular heartbeat it may leads to heart attack.

Low level of potassium called hypokalemia. It may cause symptoms like heart palpitations and leads to serious heart condition.

John is a physician who is interested in learning to what extent running affects heart rate in 18-25 year-olds. John believes that only a minority of 18-25 year-olds will experience a heart rate of at least 120 beats per minute (bpm) after running a mile. John gets a random sample of people aged from 18-25 to run a mile and records their heart rate. He finds that 40% have a heart rate of at least 120 bpm. He conducts a...

Answer the following: Describe the mechanisms by which acetylcholine affects heart rate. Describe the mechanisms by which epinephrine affects heart rate. Describe the mechanisms by which atropine followed by acetylcholine affects heart rate. Epinephrine mimics the effects of which branch of the autonomic nervous system? Compare the effect of acetylcholine on cardiac muscle with its effect on skeletal muscle. Can you explain the mechanistic basis for the difference?

5. Write an essay explaining how potassium chloride stops the heart. I understand that the potassium chloride will disrupt the electrical signaling of potassium and sodium ions which maintain the heartbeat, but I need to know more of the mechanism of the process with how it does so. If you could explain. Thank you.

This question is about the potassium ion: 1) what does potassium do at the passive potassium channels of neurons, 2) what is the role for potassium in the voltage-gated potassium channels, and 3) what is the role of potassium in chemically-gated channels that open a channel for potassium? Also, for 1), 2), and 3), where are each of these located on the neuron?

Identify the Test that is required and explain why: A researcher uses heart rate as a measure of excitability in rats. He knows the average heart rate in rats and compares his sample of rats to that average. The sample has been bred with the hope that as a group the rats have a less excitable temperament.
