Figure 3: Clinical outcomes regarding cardiac survival rate among patients without VT/VF, those with early VT/VF, and those with late VT/VF during the 30-day period. Notes: log-rank test p <0.001 for comparisons between patients without VT/VF and those with early VT/VF, those without VT/VF, and those with late VT/VF, and between those with early VT/VF and those with late VT/VF. VT/VF: ventricular tachycardia or ventricular fibrillation.
