Evidence suggests a reduced incidence of ventricular and atrial arrhythmias in patients with dapagliflozin or empagliflozin treatment. It is unclear to what extent the reduced arrhythmia burden is due to direct effects of the SGLT2 inhibitors or is solely a marker of improved cardiac function.

Age is an independent risk factor for the development of atrial fibrillation (AF). While AF arises in old age, the combined effects of widespread structural, electrophysiological and autonomic remodeling make it difficult to discern the exact mechanisms of arrhythmia generation.

BACKGROUND:The relationship between heart failure (HF) and atrial fibrillation (AF) is clear, with up to half of patients with HF progressing to AF. The pathophysiological basis of AF in the context of HF is presumed to result from atrial remodeling. We found that FOG2 repressed atrial gene expression promoted byTBX5.

Since the patient was stable and tolerating the arrhythmia it was decided to treat with IV Amiodarone for medical conversion. Whenever it is this fast, you need to be very careful to ascertain whether it is irregular ( as in atrial fibrillation with rapid ventricular respsonse ) or regular ( as in VT ). It is not VT; it is AF.
