The authors report a case of a 64-year-old woman who presented with breathlessness on exertion for 6 months, for which coronary angiogram (CAG) was done, which showed single-vessel disease of the left anterior descending coronary artery (LAD). The patient underwent PTCA + DES (percutaneous transluminal coronary angioplasty + drug-eluting stent) to mid LAD. On the third postprocedural day, she complained of palpitations with chest pain. Electrocardiographic monitor showed wide complex QRS tachycardia and she was hemodynamically stable. Further evaluation showed potassium of 2.8 mEq/L, for which intravenous (IV) KCl (potassium chloride) correction was given, and recheck CAG was done, which showed patent stent. Meanwhile, the patient was evaluated for the cause of hypokalemia, and no definite cause was evident.
