Figure 4 : 

Prevalence of ‘J waves’ in those with ventricular fibrillation (VF) during acute coronary syndrome and inhospital mortality. The prevalences of ‘J waves’ in the study and control groups are shown in the centre of the figure. Inhospital mortality is shown on each side for the four subgroups, which are: (1) ‘J wave’ and VF; (2) ‘J wave’ and no VF; (3) absence of J wave and VF; (4) absence of J wave and no VF. Same subgroups as in Table 3.
