<prompt> Answer this question truthfullyCould you provide me with the current phrasing of the statement that needs to be rephrased?  <response>: <reason> There is insufficient evidence to recommend routine screening for Catecholaminergic polymorphic ventricular tachycardia. But screening among relatives is indicated when a likely pathogenetic mutation is identified in clinically affected index cases. Screening methods for CPVT are exercise stress testing and genetic testing.
