This is the third shock, since
two programmable shocks
have been delivered.
When the rhythm decelerates to the VT-1 zone, ATP2 of the VT-1 zone is
not delivered since a shock had already been delivered in the VT zone. So
the next higher strength therapy (Shock 1 of the VT-1 zone) is delivered.

If the arrhythmia persists in the VT-1 zone after the second shock delivery,
no further shock therapy will be delivered unless the arrhythmia accelerates
to a higher zone since Shocks 3-5 are programmed Off in the VT-1 zone.
