Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. For example — bradycardia and AV conduction disturbances are not uncommon with Hyperkalemia , with these conduction disturbances most often resolving once serum K+ is corrected. She was started on isoprenalin (isoproterenol).

RBBB is no longer seen after conversion to sinus rhythm — which supports our suspicion that the intermittent RBBB conduction seen every-other-beat during the tachycardia ( in Figure-1 ) was rate-related. Note that QRS morphology after conversion to sinus rhythm is very similar to QRS morphology of odd-numbered beats during the tachycardia.

This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). He required multiple defibrillations within a period of a few hours.

Abstract Introduction Severe transitory episodes of bradycardia with subsequent syncope in children are common, and generally portend a benign prognosis. Patients with SP or AVB, 21 years of age or younger, who underwent CNA between 2015 and 2021 were included. Methods This is a single-center, case series study. The median age was 18.9

After initiating treatment for hyperkalemia, repeat ECG showed resolution of Brugada pattern: The ECG shows sinus tachycardia. ST elevation in aVL with reciprocal ST depression in the inferior leads Shock, bradycardia, ST Elevation in V1 and V2. He also received insulin with D50, sodium bicarbonate, and kayexalate for hyperkalemia.

All costs are reported in 2021 US dollars. The mean cost per hospital discharge was the highest for peripheral vascular disease ($33 700 [95% CI, $33 300–$34 000]) and ventricular tachycardia/ventricular fibrillation ($32 500 [95% CI, $32 100–$32 900]).

There was never ventricular fibrillation (VF) or ventricular tachycardia (VT), no shockable rhythm. Here is a similar case: Collapse, Ventricular Tachycardia, Cardioverted, Comatose on Arrival. Agitation, Confusion, and Unusual Wide Complex Tachycardia. There is sinus tachycardia at ~115/minute.
