I an new here. After 6 years of no incidents my ICD decided to fire 5 months ago. After various checks and re calibration of unit plus change of some medication and the addition of 100mg Amioderone I have not had any further incidents however I have an ongoing fear of the unit firing again and have noticed a bit of a drop in physical capabilities. ie stairs, gradients when walking and walking in general. Has anybody else out there experienced these issues.
