Her Apple Watch suddenly told her that she is in atrial fibrillation. Patients with healthy AV nodes who are not on AV nodal blockers and who are not hyperkalemic should have a rapid ventricular response if they have paroxysmal Atrial fibrillation. Exam was completely normal except for an irregular heart rate.

She also has a hx of paroxysmal atrial fibrillation and is on oral anticoagulant treatment. She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Are you confident there is no ischemia? The heart rate could be compatible with that of a 2:1 conducted atrial flutter.
