An ECG, or electrocardiogram, is a medical test that records the electrical activity of the heart. It's like a graph that shows how the heart is working. If the heart beats in a regular rhythm and at the right speed, the ECG is said to be normal. However, if there are unusual patterns or speeds, this could indicate a problem with the heart. For example, "flipped T-waves" refers to a specific pattern on the ECG that can suggest different heart conditions.
