Web1 Jul 2015 · This doesn't look too bad, but remember that the VOO pacemaker is totally unconcerned about when it fires. If it happens to fire during the "vulnerable period", it may produce an R wave on top of a T wave (the R - on - T phenomenon) which will then give rise to a polymorphic VT or VF. This risk of R on T is great, and well-documented.
