Not All “Idiopathic” <scp>PVCs</scp> Are Benign: Concealed Long <scp>QT</scp> Syndrome Unmasked by <scp>RVOT PVC</scp> Ablation
A young woman undergoing ablation for presumed idiopathic RVOT PVC developed torsades de pointes and was diagnosed with concealed LQT1. Subtle rate-dependent repolarization abnormalities on pre-ablation ECG may signal LQT1; careful ECG scrutiny is essential before intervention, as not all PVCs from the RVOT are benign.
