Key result
The duration of the base of the triangle at 0.5 mV from high take-off ≥160 ms accurately distinguished Type-2 Brugada pattern from healthy athletes (specificity 95.6%, sensitivity 85%).
Why the study?
Do new ECG criteria based on the r'-wave triangle in leads V1-V2 accurately differentiate Type-2 Brugada pattern from healthy athletes?
Case-Control (n=108)
Do new ECG criteria based on the r'-wave triangle in leads V1-V2 accurately differentiate Type-2 Brugada pattern from healthy athletes?
New ECG criteria based on the r'-wave triangle in leads V1-V2 can accurately distinguish Type-2 Brugada pattern from the normal r'-wave pattern seen in healthy athletes.
No takes yet. Share an insight, caveat, or question.
May aid ECG differentiation of Type-2 Brugada pattern in athletes; leaves open prospective validation before clinical adoption.
Serra et al. (2014) conducted a case-control in Type-2 Brugada pattern (n=108). New ECG criteria (triangle base duration at 0.5 mV from high take-off ≥160 ms) was evaluated on Differentiation of Type-2 Brugada pattern from healthy athletes with r'-wave in leads V1-V2. The duration of the base of the triangle at 0.5 mV from high take-off ≥160 ms accurately distinguished Type-2 Brugada pattern from healthy athletes (specificity 95.6%, sensitivity 85%).
