Echocardiogram, ct heart scan or cardiac mri. what does each one test for and how accurate are they? holter results less than 1% of beats pacs an pvcs

Imaging tests: Echo uses sound waves to image cardiac structure and function. Ct scan uses computerized x-ray examination to do similar imaging and MRI uses yet another technology. Echo gives real time wall motion imaging while the other two are almost real time. They are all very accurate and each has its own strengths and weaknesses. We choose depending on what specifically we need in information.
