Subgroup analysis of the percentage of patients who developed new arrhythmias by 168 h after randomisation.

The size of the markers represents the number of patients included in the subgroup. Hazard ratios are plotted on a log-scale. Results of the multivariate analysis with adjustment for age and heart rate at baseline are shown in Fig. S2.

APACHE = Acute Physiology and Chronic Health Evaluation; ARDS = acute respiratory distress syndrome; beats/min = beats per minute; CI = confidence interval; eGFR = estimated glomerular filtration rate; NC = upper limit not calculable; SOFA = Sequential Organ Failure Assessment.
