Cell phone heart rate measurement is generally inaccurate, there are some errors, if you want to have a more accurate test results, it is recommended to go to the local hospital to receive ECG test.
The speed of the heart rate will directly affect the health of the human body, and cell phone heart rate measurement may have some errors, so it is recommended that patients do not take the heart rate detected by the cell phone as the basis for diagnosis, but rather more professional testing as the basis for diagnosis, such as electrocardiogram testing, etc. Moreover, in most cases, cell phone measurements are not the heart rate, but the pulse, but the pulse and the heart rate are not identical, there are certain differences, such as atrial fibrillation patients whose pulse number is lower than the number of heart rate, the heart rate is lower than the number of patients with atrial fibrillation. For example, in patients with atrial fibrillation, the pulse number is lower than the heart rate number.
In addition, cell phones can be interfered with by clothing or other substances, further reducing their accuracy, so it is not recommended that patients test their heart rate in this way.
