This wide QRS complex tachycardia has a typical left bundle branch block pattern, but two things give the clue that this is ventricular tachycardia. There is a fusion beat (second from left) present ...

QRS interval widening appears to be highly specific for the diagnosis of hyperkalemia in patients with end-stage kidney disease. ECG changes, in general, have poor sensitivities for hyperkalemia in ...
