Nothing would touch these episodes - the doctor and I tried increasing verapamil, <span style = 'background-color: #dae8f4'>digoxin</span>
and flecainide. The only thing that would terminate these episodes was a large oral dose of magnesium and potassium. However, the doctor remained skeptical that the magnesium was helping.
About two months ago after another attack of tachycardia that I terminated with the mag and potassium, I quit taking the verapamil.
