This causes the blood runs the wrong way and the heart production falls. This condition causes by VVI pacemaker can be resolved by reprogramming the pacemaker or replacement for a dual chamber pacemaker.VVI pacemaker is not sufficient when the ventricles are not able to beat together in the cases of congestive cardiac failure and then dual chamber pacemaker is required.Possible problems during implementation of VVI pacemakers are: 1  collapsed lung. 2  infection.VI pacemaker is not sufficient when the ventricles are not able to beat together in the cases of congestive cardiac failure and then dual chamber pacemaker is required.
