The wall mountable lighting fixture does not require tools to attach and remove the fixture from a wall surface. The wall mountable lighting fixture includes an attachment mechanism that can be manipulated from a first position to a second position by the push of a button. The button is pressed and the dimension of the attachment mechanism is increased and placed about the edges of a DIN rail attached to the wall.

Methods and devices are disclosed for employing mechanical measurements to synchronize contractions of ventricular wall locations. Accelerometers that may be placed within electrode leads are positioned at ventricular wall locations, such as the left ventricle free wall, right ventricle free wall, and the anterior wall/septum wall. The accelerometers produce signals in response to the motion of the ventricular wall locations.
