Nice strips! I often end up correcting folks who confuse coarse VF for TdP. Most people would have allowed a VF or two to slip into the mix, but I think these are all legit torsades. #4 is the one that's borderline—it's almost a touch too disorganized and a touch too fast for typical TdP—but I agree that it probably still is. Thanks for your consistently excellent collections of tracings.
