Ep. 19 - Current ECG + Master Your Medics | TCA Overdose Case Study

On this episode, Current ECG teams up with Master Your Medics to present a TCA Overdose case! Dave discusses the pathophysiology behind sodium channel blocking medications and how they affect cardiac depolarization at the cellular level. This is important because it affects how we interpret the ECG. Cardiac toxicity can develop quickly in TCA overdose, so get an ECG early in the clinical course if suspecting the diagnosis. Dave also discusses how sodium bicarbonate works to alter the patients ph level as well as competitively binding to sodium channel receptors helping to reverse the acidosis and TCA availability in the blood. Treatment options include: Oxygen Sodium bicarbonate for a QRS complex wider than 100ms. Assisted ventilations via BVM with potential for early intubation consideration which will help to blow off C02 0.9% Normal Saline What are some signs of TCA Overdose on the ECG? Sinus Tachycardia – most frequent dysrhythmia Widening of the QRS complex Prolongation of the PR or QT interval Right bundle branch block Non-specific intraventricular conduction delay (IVCD) Brugada pattern Wide-complex tachycardia (not ventricular tachycardia) Ventricular tachycardia / fibrillation How wide is too wide?
