What Treatments Are Available for QRS Widening Due to Toxicity?
Management strategies depend on the underlying cause of the QRS widening:
Sodium Bicarbonate: Commonly used in TCA overdose to narrow the QRS complex by reversing sodium channel blockade. Antiarrhythmics: In some cases, specific antiarrhythmic drugs may be administered to stabilize the cardiac rhythm. Electrolyte Management: Correcting electrolyte imbalances, such as administering calcium gluconate for hyperkalemia, can also normalize the QRS complex.
