Table 1 Results of systolic ShMOLLI T1 map acquisitions in patients with tachyarrhythmia—either atrial fibrillation (AF) or sinus tachycardia (ST). The majority of acquisitions were undertaken with TD 0 ms (resulting in trigger times ≤ 223 ms) but in five patients a different systolic TD was chosen by the operator. All short-axis systolic T1 maps acquired for each patient are included in this analysis
