There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). If there had been — a temporary atrial pacemaker could have been considered as a way of increasing the heart rate to suppress a bradycardia-dependent arrhythmia ("overdrive pacing").

Our collaboration with Orchestra BioMed will explore how cardiac pacing can go beyond management of bradycardia and conduction disease to treat hypertension as well,” said Robert C. Heart Disease and Stroke Statistics – 2017 Update: A Report from the American Heart Association. Circulation. 2017; 135: e146. Kowal, M.D.,

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].

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). 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.
