Butterfly and reverse butterfly: usefulness of a resistance band to provoke exercise-induced arrhythmias during catheter ablation in a patient refractory to pharmacological stimulation

Ventricular arrhythmias arising from the right ventricular outflow tract (RVOT-VA) are a frequent finding in young physically active patients . Catheter ablation represents a widely accepted therapeutic option for patients suffering from symptomatic RVOT-VA. However, the exact localization and ablation can be hindered by a low arrhythmia burden during the ablation procedure. In these particular cases, pharmacological stimulation may help increasing the number of RVOT-VA during the procedure. However, even extensive pharmacological stimulation may fail inducing the clinical arrhythmia. Elastic exercise bands (resistance bands) are widely used for strength training in healthy individuals as well as in patients recovering from surgery or phases of prolonged inactivity . Resistance bands are inexpensive and readily available, and exercise can be performed in almost any body position including the supine position. In this case, we tested whether intraprocedural exercise using a...
