Table 4. Comparison of Brugada wave and J wave excluding V1-V3.
| Brugada wave | J wave excluding V1-V3 | |
|---|---|---|
| Male dominance | Yes | Yes |
| Age | Young to middle-Aged | Young to middle-aged |
| Incidence | Lower | Higher |
| Incidence of VF | Higher | Lower |
| VF trigger | Short-coupled PVC | Short-coupled PVC |
| Ameliorative response to quinidine | Yes | Yes |
| Dynamic changes | Common | Only in those prominent J wave that may be associated with VF |
| Bradycardia or pause dependent accentuation | Yes | Yes, but more significant in those prominent J wave |
| Vagally-mediated accentuation | Yes | Yes, but more significant in those prominent J wave |
| Induction or augmentation by hypothermia | Rare, particularly in V1 | Common |
| Induction or augmentation by fever | Relatively common | Rare |
VF: ventricular fibrillation
