when a patient has an m.i. one of the electrolytes looked with the heart is potassium. however, it is also important to understand the physiology of the heart and it's electrical system. potassium has a direct effect on the electrical system of the heart. in addition, sodium and calcium are crucial to the muscular activity of the actual heart beat. so these three electrolytes are most important. you need to look at the cellular physiology of the heart and the heart muscle to get a better understanding of why these electrolytes are the most important when the heart is infarcting. these are the electrolytes that are looked at in the acute stages and brought back into balance as soon as possible. among the drugs used to treat will be potassium and calcium channel blockers.
here is a short tutorial on potassium.
- a discussion about heart attacks from lab tests online. make sure you click at the bottom of the page to get to all pages and note the listing of all the relevant lab tests ordered for someone suspected of having an m.i.
electrolytes important in the functioning of the heart:
- blood tests to evaluate heart disease
just in case you need a tutorial on the electrical pathway of the heart, here is a great site to help understand that:
- cyberheart - tutorials for basic heart anatomy, physiology and ekgs from professor crimando at gateway community college
here is some information on heart attack and electrolytes
information on myocardial infarction:
- physician guidelines for immediate management of myocardial infarction
- is the main site and the next link is more specifically on heart attacks
- may need to register (it's free) in order to view entire text of articles and videos - this site is more for patients, but i like it because it has great animated videos of all kinds of heart anatomy and heart related procedures
