The rule of thumb is less accurate, and the risk is higher because a long QT in the presence of bradycardia ("pause dependent" Torsades) predisposes to Torsades. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval. 3) At heart rates below 60, far more caution is due.

For now, the 2017 AHA/ACC/HRS guidelines for asymptomatic patients that have inducible types of Brugada syndrome recommend observation without any specific therapies or interventions [8]. Induced Brugada-type electrocardiogram, a sign for imminent malignant arrhythmias. Heart Rhythm, 13(7): 1515-1520. [2]:

Abnormal Electrocardiogram (ECG): Defined (San Fran syncope rule) as any new changes when compared to the last ECG or presence of non-sinus rhythm. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful. Abnormal ECG – looks for cardiac syncope.

Theres sinus bradycardia, borderline PR interval, narrow QRS; normal axis/R wave progression; low precordial voltages, and subtle peaked T waves (most obvious in V2, but all T waves are symmetric with a narrow base). Theres no prior ECG to compare - but the bradycardia, prolonged PR and peaked T waves could all be from hyperkalemia.

This is based on the Sieira et al, 2017, risk calculator , which gives a borderline risk score (2). Regardless of further evaluation, she should avoid bradycardia, AV nodal blockers, Na channel blockers, and fevers. --If Follow up the next AM: Brugada pattern is resolved Below is what the electrophysiologist recommended.
