Hi my dad is 77 years old. Led an extremely healthy life - no ailments except irregular heart beat diagnosed in 2008. He wasn't on any meds. Last November he was diagnosed with bullous pemphigoid for which he was prescribed wysolone and endoxan. He has suffered from palpitations since then,been to ER three times in last 1.5 months. He is in the hospital being administered corderone and metalor. I feel that the wysolone may be causing it but the doctors are treating the symptoms not the cause.
