The rule of thumb is less accurate, and the risk is higher because a long QT in the presence of bradycardia ("pause dependent" Torsades) predisposes to Torsades. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval. Other Research: According to this study b y Batchvarov et al. ,

To improve visualization — I've digitized the original ECG using PMcardio ) MY Thoughts on the ECG in Figure-1: This is a challenging tracing to interpret — because there is marked bradycardia with an irregular rhythm and a change in QRS morphology.
