The pacemakers senses signals on the marker  
The pacemakers senses signals on the marker channel that do not correspond to the ECG pattern. This can be physiologic (e.g. ventricular pulse or myopotentials) or non-physiologic (e.g. lead fracture or if the lead is loose from the pacemaker pulse generator or outside interference such as TENS therapy or surgical diathermy).

ICDs are implanted under local anaesthesia in a sterile operating room or catheterization laboratory. Transvenous ICD implantation starts, like pacemaker implantation, with inserting the ICD leads in the left or right cephalic vein. Fluoroscopy is used to ensure the appropriate location in the atrium or ventricle. Leads are often positioned in the auricle of the right atrium and/or the right ventricular apex.
