Dr. Smith's ECG Blog

He also had a history of chronic kidney disease, stage III. Angio had shown some acute disease in the saphenous vein graft to the posterior descending artery off of the RCA. There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Most recent echo showed EF of 60%.

Potassium 6.2 with narrow QRS: any indication for calcium?

Dr. Smith's ECG Blog

Theres no prior ECG to compare - but the bradycardia, prolonged PR and peaked T waves could all be from hyperkalemia.
