I was wondering if anyone can tell me what a 24 hour holter monitor can determine? I had asked the nurse who hooked me up and her reply was alot of things. Can a holter monitor show blockages or a previous heart attack? I had one done last week and I am still waiting on results.
1. Abnormally fast or irregular heart rhythms.
2. Abnormally slow heart rhythms.
3. Abnormal conduction of cardiac impulses, which may suggest underlying cardiac or metabolic disorders.
4. Evidence of the occurrence of a prior heart attack (myocardial infarction).
5. Evidence of an evolving, acute heart attack.
6. Evidence of an acute impairment to blood flow to the heart during an episode of a threatened heart attack (unstable angina).
7. Adverse effects on the heart from various heart diseases or systemic diseases (such as high blood pressure, thyroid conditions, etc.).
8. Adverse effects on the heart from certain lung conditions (such as emphysema, pulmonary embolus (blood clots to lung), etc.).
9. Certain congenital heart abnormalities.
10. Evidence of abnormal blood electrolytes (potassium, calcium, magnesium).
11. Evidence of inflammation of the heart or its lining (myocarditis, pericarditis).

Reason: I orig. edited to change from a link to just the website, but neither is acceptable here, I guess.
What is Holter Monitor? A Holter monitor is a continuous tape recording of a patient's EKG for 24 hours. Since it can be worn during the patient's regular daily activities, it helps the physician correlate symptoms of dizziness, palpitations (a sensation of fast or irregular heart rhythm) or black outs. Since the recording covers 24 hours, on a continuous basis, Holter monitoring is much more likely to detect an abnormal heart rhythm when compared to the EKG which lasts less than a minute. It can also help evaluate the patient's EKG during episodes of chest pain, during which time there may be telltale changes to suggest ischemia (pronounced is-keem-ya) or reduced blood supply to the muscle of the left ventricle.
How will the physician know you're walking or doing something that can raise the heart beats while wearing this? For example, if you're wearing the holter and taking a walk that can speed up the heart rate, won't that appear and how does he/she know that was the time you were walking or doing something physical?
You keep a log, but usually this is for when you experience symptoms so they can then corrolate it with the ekg. I think if you are concerned your heart rate will go up then it would be something you would write down.
A few years ago I was on a 24 hour holter monitor and they gave me a little booklet and I had to write down everything I did all day, even when I go to the bathroom they told me. I do an exercise walk every day, so I wrote down exactly when I started to walk and when I stopped, and so forth.
