The first ECG in this case showed sinus tachycardia with a widened QRS (black arrow), a rightward axis, prolonged corrected QT interval (QTc), and terminal R wave in AVR (white arrow). There are several potential causes for these ECG findings, but put together with the patient’s history, we were suspicious of sodium channel blockers being the most likely cause. The second ECG, after sodium bicarbonate was administered, demonstrated a normal QRS (black arrow) and no rightward axis deviation, reduction of the QTC and resolution of the terminal R wave (white arrow). We later learned that the patient’s cardiologist recently increased her propafenone dose.
