Will an echocardiogram show any arrhythmias?
While getting an echocardiogram, they may see that your heart is beating irregularly, but it is not the best test to detect an arrhythmia. The best test for this would be an electrocardiogram, commonly called an EKG. This shows us the electrical activity of the heart and allows physicians to diagnose arrhythmias. Echocardiograms are best at showing us the actual function of the heart, allowing us to measure wall thickness, and allowing us to see if the blood flow through the heart and heart valves is normal.
