Risk stratification of sudden cardiac death in Brugada syndrome: an updated review of literature

The Egyptian Heart Journal

Table 1 Summary table of SCD risk stratification components and their references

Parameters	Influence on arrhythmic risk	References
Aborted sudden cardiac death	Increases the risk	[11, 14]
Presumed arrhythmic syncope	Increases the risk	[15,16,17,18,19,20,21,22]
Electrical pattern of BrS	Increases the risk	[37,38,39,40,41,42,43]
Age > 60 years old	Decreases the risk but needs to be confirmed	[33]
Female gender	Decreases the risk	[30, 34, 35]
VF inducibility in programmed ventricular stimulation	Increases the risk but there is a conflictual data	[5, 52, 53]
Sinus node dysfunction	Increases the risk but needs to be confirmed	[30, 33]
Fragmented QRS	Increases the risk but needs to be confirmed	[32, 45]
Early repolarization	Increases the risk but needs to be confirmed	[47,48,49]
Type 1 pattern in the inferior leads	Increases the risk but needs to be confirmed	[46, 48, 50]
