Anti-interference electrocardiographic examination device

The invention belongs to the technical field of electrocardiographic examination, and particularly relates to an anti-interference electrocardiographic examination device which comprises an electrocardiographic examination instrument and a signal shielding device mounted on the surface of the electrocardiographic examination instrument, and further comprises a storage assembly arranged on the surface of the electrocardiographic examination instrument. The storage assembly comprises a placement box, a baffle, a rectangular iron plate and a winding block, the placement box is fixedly connected to the face, away from the signal shielding device, of the electrocardiograph, and a limiting groove is formed in the inner wall face of the placement box; according to the electrocardiograph, the detection line can be conveniently stored, the phenomenon that the detection line is lost and lost due to the fact that the detection line is randomly placed after the electrocardiograph is used is avoided, the signal shielding
