Hi,
There are tests that can check the function of the heart such as ECG, echo, treadmill, cardiac angiogram, and holter. The ecg would look at the
heart rate, rhythm and can also identify if there are areas not getting enough blood or signs of a previous
heart attack. The Echo can look at the overall size of the heart, the size of the different chambers, how the walls are moving and how effectively the heart receives and lets out blood.
The treadmill would look at the body's response during periods of physical
stress to see if there is a change in blood supply. The cardiac angiogram would look into the blood vessels to see if there are any blockages. The holter is essentially a 24 hour ECG, would look to see if there are times in the day where there is a change in the heart rate and rhythm.The heart test chosen would depend on his signs and symptoms but initial test are usually an ECG and echo.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Michelle Gibson James
