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. The ECG was interpreted as showing atrial flutter with 2:1 conduction. The last echocardiography 12 months ago showed HFmrEF.

Negative predictors of adverse outcome: Pacemaker Pre-syncope or "near-syncope," but there is still some small risk (5, 18) These last two are identified in studies, but I consider them dangerous signs and symptoms in their own right, as above: 10. —QRS Syncope with Exertion (EGSYS) 7. S yncope while supine (EGSYS) 8. orthostatic vitals b.
