The development of the ERG 911 LS is based on the technology of the ERG 911 L couch/semi-couch safety ergometers.

Thanks to an additional pivot axis of the couch, the patient can be positioned in an angle of up to 45 degrees to the left during exercise. This ensures a particularly favourable position for high-quality ultra-sound images during stress echocardiography. The stable shoulder support ensures a comfortable and safe positioning of the patient while the couch is tilted to the left.
