“…179,180,182,183,[219][220][221][222][223][224][225][226][227] In this regard, in 2010 the ESC offered revised recommendations for defining abnormalities in ECGs in trained athletes, 183 with the intent to create a mechanism for reducing expected false-positive results (and increasing specificity) in preparticipation screening ECGs, that is, from unacceptably high rates of up to 15% to 20% to rates of ≤5%. ** This strategy has been based in part on the assumed premise that in young athletes and other young people, isolated increases in QRS voltages (in the absence of other pattern alterations) have limited specificity and are unlikely to be indicative of pathological hypertrophy (eg, as encountered in HCM).…”
