What gives better heart info, an ekg, angiogram or a cardiac CT scan?

All important. All are important -- ekg provides electrical and rhythm information. Much can be learned from an ekg. Angiogram/cardiac ct provides anatomic information about coronary arteries and myocardium (muscle of the heart).
Dependent. Selection based on patients conditions to determine the type of examination.

Been getting heart palpitations and an off balance for awhile now. Had 4 ekgs. Blood work. Chest xray. Ct scan-angiogram. All normal. Heart good?

Maybe. If you were having palpitations at the time ECG was done and ECG was normal, then palpitation is not related to heart rhythm abnormalities. The normal studies mentioned do not necessarily rule out all cardiac disease. Depending on symptoms and frequency, echocardiogram and/or ECG monitoring may be considered. Consider seeing a cardiologist for further evaluation. Read more...

I have to have a cardiac ct scan. The dr said I will get BB to slow heart rate? Will it be in a pill?

For short term. it is probably intravenous. CT of heart can be overstated on the importance of the results. About 90 % of middle aged people have some hardening of the arteries. This is not very predictive of heart attack nor a reason for stents/bipass. Read more...

Can a cardiac ct scan show soft plaque in heart?

I don't believe it c. Cardiac CT scan mainly shows calcium deposits which are only present in a mature plaque. So a soft plaque is not visible in the coronary arteries(that is where they locate themselves, not in the heart itself). Read more...

How slow does your heart rate have to be for a cardiac ct scan?

It depends on the. scanner. If it is 64 slice scanner, HR should be 65 or less. The slower the heart rate, the better the pictures. Docs use beta blocker meds to decrease the heart rate. I give 25-100 mg as needed. If someone's HR is over 90 before going for scan (before the meds), it can be hard to get HR down. If it is a high speed scanner, HR could be faster.

Dear wants to check for plaque in heart. He's doing a cardiac ct scan with contrast. Is this a good test for this?

Yes. The cardiac CT is a very accurate test for seeing any plaque (cholesterol buildup) in the heart. It is more sensitive than an angiogram at seeing early blockages. It is more sensitive than a nuclear stress test, stress echo, or treadmill stress test. Check out my website CardioGauge.com for heart health education. Best wishes! Read more...

If my total body exposure to radiation is 22 msv, how much more radiation is my heart exposed to in a cardiac CT scan?

Not sure. I have not seen the radiation dose to the heart specifically separated out. In general cardiac ct will result in around 7-15 msv exposure. The newer generation scanners are using a lower dose of radiation so this value is dropping. Read more...
Not sure. You would need a medical physicist to calculate the actual exposure dose. Read more...
