Intravenous push of lidocaine for premature ventricular contractions, can it be toxic?

Lidocaine treatment of ventricular premature beats will not be poisoned.
1. Lidocaine belongs to anesthesia and anti-arrhythmic drugs, mainly used for infiltration anesthesia, epidural anesthesia and the treatment of ventricular arrhythmia, acute myocardial infarction and frequent ventricular premature beats caused by digitalis intoxication. Adverse reactions mainly include drowsiness, sensory abnormalities and respiratory depression and bradycardia, atrioventricular block.
2. Premature ventricular contraction, also called ventricular pre-systole, is due to the ectopic pacing point of the ventricle sends out impulses in advance, causing abnormal contraction of the ventricle. Physiological premature ventricular contraction can be relieved by relieving mental stress and improving life; pathological premature ventricular contraction should be evaluated by cardiologists and then treated symptomatically, mainly by treating the primary disease, and catheter ablation can be carried out for the severe cases.
Lidocaine needs to be used under medical supervision, do not self-medicate.
