Ischemia Testing and the Monomorphic VT Storm: Crossed Wires

Patients with a severe form of ventricular arrhythmia who may be referred for catheter ablation are often screened first for coronary artery disease (CAD) or ischemia. Researchers conclude, based on registry data, that such testing rarely affects the subsequent management or outcomes.

The findings, they say, call into doubt routine CAD/ischemia testing in patients like those studied, who had episodes of monomorphic ventricular tachyc....
