Study of gekoTM Interaction With Cardiac Pacemakers

The gekoTM device is a small disposable battery powered device that attaches to the lower leg near the knee and stimulates the common peroneal nerve, causing muscle contraction of the lower leg. This contraction increases blood flow and the device is used to treat several conditions including deep vein thrombosis and venous leg ulcers. There is evidence that some powered muscle stimulators and related devices can affect Cardiac Demand Pacemakers. This study is to ascertain if there is any such interaction between the gekoTM device and permanently implanted cardiac pacemakers.
