Flecainide,
Digoxin, Atenolol, verapamil can go into the bin. Also, the holter monitor report mentioned "ventricular runs" is not meant to v-tach. It is ventricular pacing. When my pacemaker is pacing my ventricle, I feel like an express train is running in my chest, sweat and exhausted.
Yes, with the pacemaker, you still can feel the irregular pulses. It depends the programming what the doc set to. If he set to permanent pace at ventricle then you might be unable to feel one.
