If you responded to a person who is sick at home and that patient has not been taking their K-Dur medicine for a few days and you find your CHF patient, who had been prescribed Labetalol, Lasix
and K-dur,
and showed monomorphic V-tach on
the monitor, would you synchonize cardiovert
the patient first if he was hemodynamically unstable knowing that he is low on potassium which might convert your patient into unwanted and nonperfusing rhythm? Would we harm the patient if we shock them?
