Primary prophylaxis, NYHA Class I-III
Private driving is permitted beginning 4 weeks after implant. Commercial driving is not permitted (disqualified)**.
A primary prophylaxis ICD has been recommended but declined by the patient
Private driving is permitted with no restriction. Commercial driving is not permitted (disqualified)**.
Secondary prophylaxis for VF or VT with decreased level of conciousness; NYHA Class I-III
Private driving is permitted beginning 6 months after the event has occured. Commercial driving is not permitted (disqualified)*.
Secondary prophylaxis for sustained VT with no associated cerebral ischemia; NYHA Class I-III
Private driving is permitted beginning 1 week post implant, in addition to the appropriate waiting period for the VT (see Ventricular Arrhythmias). Commercial driving is not permitted (disqualified)**.
Any event resulting in device therapies being delivered (shock or ATP), in which level of conciousness was impaired, or the therapy(ies) delivered by the device was/were disabling
Private driving is permitted following 6 months restriction. Commercial driving is not permitted (disqualified)**.

*The 6 month period begins not at the time of ICD implant, but rather at the time of the last documented episode of sustained symptomatic ventricular tachycardia (VT), or syncope judged to be likely due to VT or cardiac arrest. For patients who have a bradycardia indication for pacing as well, the additional criteria under the permanent pacemaker section also apply. All patients must be followed from a technical standpoint in a device clinic with appropriate expertise.

**ICDs may sometimes be implanted in low-risk patients. Individual cases may be made for allowing a commercial driver to continue driving with an ICD provided the annual risk of sudden incapacitation is believed to be 1% or less.
