What's the source of the unusual electrocardiogram (ECG) findings in a patient presenting with dizziness and limb weakness? That's the mystery posed in a recent case report. The diagnostic challenge ...

There are only a few sinus rhythm QRS complexes available to examine on this ECG. Using lead V1 an incomplete right bundle branch block is seen. A prolonged QT interval is present that extends all the ...
