“…We therefore hypothesize SSEP stimulation may trigger a vasovagal reaction, similar to the proposed mechanism for dural traction-induced arrhythmia. Indeed, case reports describe bradycardia or/and asystole which normalize with cessation of MEPs or SSEPs [ 18 , 19 ], MEPs have also been implicated in the conversion from hemiblock to complete heart block in a case report [20] , similar to our observation in Case 4. The mechanism by which SSEP stimulation causes arrhythmia may be via afferents from peripheral nerves which trigger a vagally mediated response which in turn depresses the sinoatrial node.…”

Highlights Although multiple factors have been implicated, our case series highlights SSEP stimulation as a common etiology of arrhythmia. Significant bradycardia and CA during spine surgery does not always require termination of the surgical procedure. Decision making should be undertaken in each case individually based on patient condition and circumstances of each event. Surgeons and anesthesiologists should be aware of and prepared to treat significant cardiac arrhythmias during spine surgery even in otherwise healthy patients without known risk factors.

“…This may disturb the heart rhythm in SEP recordings and even may cause cardiac arrest (Morano and Tung, 2019). Although very rare, transcranial stimulation is reported to cause bradycardia (Ponder et al, 2003) or affect the heart rhythm as shown in Fig. 5.2 in our own experience.…”

“…Electric currents can also activate the heart muscle by eliciting triggering effects on heart rhythm, induction of brady-and tachycardia, atrial or ventricular fibrillation, and heart failure (Ponder et al, 2003;Morano and Tung, 2019). Fatal ventricular fibrillation with a probability of 100% will occur at a current from an intracardiac electrode of only 0.5 mA.…”
