A 50yo pt with h/o of HTN, DM and end-stage renal disease is admitted due to dyspnea and change in sensorium.
This looked like the REALLY WIDE QRS tachycardia mentioned in Dr. Amal Mattu's blog --->>> Consider toxic/metabolic causes. The K came back 8.5 (hyperkalemia). Because of the dyspnea, pt was intubated and calcium gluconate, NaHCO3, insulin and kayexalte were given. Patient was dialyzed. After a few days pt was discharged improved.
