Do I need to calibrate for ECG measurements?

In the case of an electrocardiogram (ECG), calibration is not typically required because the device is designed to accurately measure the electrical activity of the heart. However, there are still some important steps to follow during the setup process to ensure that the ECG measurements are accurate.

One of these steps is selecting the position of the watch on the wrist. It is important to wear the watch on the wrist that is specified in the instructions, as this can affect the accuracy of the ECG measurements. For example, if you are using a Samsung Galaxy Smart Watch, the instructions may specify that the watch should be worn on the non-dominant wrist. This means that if you are right-handed, you should wear the watch on your left wrist, and vice versa.

In addition to selecting the correct wrist position, it is also important to follow any other instructions provided in the setup process, such as ensuring that the watch is securely fastened to the wrist and that the sensors are in contact with the skin. By following these instructions, you can help ensure that the ECG measurements are accurate and reliable.
