A rate-independent method of assessing QT-RR slope following conversion of atrial fibrillation.

abstract：:Similar to the surgical mini-maze procedure, the posterior "box" lesion set employs linear ablation lesions along the anterior aspects of both sets of PVs connected by a roof line and an inferior line to electrically isolate the PVs and complete posterior LA wall en masse. However, creating fully transmural linear atr...
