My crt icd device developed a safety mode error.As i have complicated heart rate management for recurrent non sustained vt and replacement mitral valve.I rapidly became very unwell and had to be rushed to hospital where they couldn't diagnose the problem due to lack of electro physiologists over weekend.Due to my regular vt episodes i had to be drugged for 4 days to stabilize heart arrhythmia which was worsened by constant pacing.I had to lay in the same position as sitting up stopped the device pacing and i got shocked.Over the period i had 6 fully conscious inappropriate shocks which was highly distressing since after 16 years of having an icd.I have never experienced one since the settings were previous to the fault set purposefully with a high threshold and trigger time.Fda safety report id # (b)(4).
