E.coli-induced diarrheal infection usually presents milder symptoms and recovers with antibiotics. But this case presents with atrial fibrillation, instead of ventricular arrhythmias which is the rarest complication of low potassium. The most prevalent sustained arrhythmia in older adults is atrial fibrillation. A three- to five-fold greater risk of stroke is linked to atrial fibrillation, as well as a greater risk of heart failure, cardiac mortality, and overall mortality. Hypokalemia (3.5 mmol/l), or low serum potassium, is thought to increase the risk of cardiovascular illness, particularly ventricular arrhythmias and cardiac arrest. The relationship between serum potassium levels and the risk of atrial fibrillation has only been briefly studied in the past. When E. coli causes diarrhoea, Low serum potassium, which is connected to a lengthening of P waves, a measure of atrial conduction. Atrial fibrillation risk has been linked to an increase in P-wave duration.
