Table 3. High cardiac risk- at T1 hypokalemia vs normokalemia after bowel cleansing.
| Hypokalemia | Normokalemia | Unadjusted | ||
| N = 104 | N = 1769 | OR (95 % CI) | P value | |
| Congestive heart failure | 4 (3.8 %) | 40 (2.3 %) | 1 | 0.31 |
| Ischemic heart disease | 10 (9.6 %) | 142 (8.0 %) | 1.22 (0.62–2.39) | 0.57 |
| Serious arrhythmias | ||||
| Atrial tachycardia 1 | 10 (9.6 %) | 128 (7.2 %) | 1.36 (0.69–2.68) | 0.37 |
| Ventricular tachycardia 2 | 0 | 1 (0.6 %) | – | 1.00 |
| Bradycardia | 0 | 2 (0.1 %) | – | 1.00 |

1
Tachycardias originating in the atria in this study include atrial fibrillation (N = 135), atrial flutter (N = 3), supraventricular tachycardia (N = 0), Wolff-Parkinson-White Syndrome (N = 0).
2
Tachycardias in the ventricles include ventricular tachycardia (N = 0), ventricular fibrillation (N = 1), long QT-syndrome (N = 0).
Note: some patients are included in ≥ 1 risk category (compared to high cardiac risk in Table 1 ).
