Is there a difference between the ECG measured at home by the Tongxinluoke ECG monitor and the ECG measured at the hospital?

Through the heart Luo Ke twelve-lead dynamic cardiac monitor is twelve-lead medical grade cardiac equipment, with the hospital twelve-lead Holter, are medical grade accuracy. So these two measured out of the ECG is almost the same, I bought a use okay, their own home can measure the ECG, do not have to go to the hospital queue, this is very convenient.
