What is the range of ECG?

The range of an electrocardiogram (ECG) typically refers to the frequencies it can detect, which is usually between 0.05 Hz to 150 Hz. This range allows the ECG to capture the electrical activity of the heart, including the P wave, QRS complex, and T wave. The standard paper speed for an ECG is 25 mm per second, which provides a clear representation of the heart's rhythms. Overall, the ECG is a crucial tool for diagnosing various cardiac conditions by analyzing these electrical signals.
