(FIT)-Module 4 Workshop 6: Electrocardiographic and Electrophysiological Correlations-Poole Case 6 Answer

Video Transcription

Video Summary

The video discusses severe hypokalemia following the reversal of digoxin toxicity with digifab. This occurs due to reactivation of the sodium-potassium pump, causing potassium to shift intracellularly, potentially leading to life-threatening conditions. Symptoms include increased thirst and muscle weakness. The video also highlights digoxin toxic rhythms, such as bidirectional VT, identifiable by AV dissociation, and atrial tachycardia with block and PBCs, showing AV node suppression and increased automaticity. Digoxin can increase intracellular calcium, triggering ventricular arrhythmias.
