subclavian approach to the cephalic approach of transvenous lead
introduction?

implanted with an ICD. At the time of implant, there is a concern that he may
be too unstable to tolerate DFT testing. An advantage of performing the DFT
testing would be:
a) Check integrity of the system
b) Check lead connections
c) Confirm adequate VF sensing
d) All of the above
D. All the above
