evidence: In the course of the patient’s atrial flutter and fibrillation, she was able to identify triggers to her episodes of atrial arrhythmias, which included lack of sleep and ingestion of cold beverages and foods. More than 5 episodes occurred and were confirmed with her home KARDIA device after consumption of cold beverages and foods, such as mango juice (Figure 2), cold soda (Figure 3), and refrigerated fruits (Figure 4). She also noted that the speed of ingestion increased reproducibility of triggered atrial fibrillation episodes.
