The Role of Sodium Bicarbonate in the Management of Some Toxic Ingestions

Figure 2

(a) Sodium channel toxicity on 12-lead ECG (taken from https://lifeinthefastlane.com). On this 12-lead ECG you can see regular wide QRS tachycardia with no clear P waves, right axis deviation, tall R wave in AVR, and poor R wave progression in precordial leads. (b) Sodium channel toxicity on 12-lead ECG after administration of sodium bicarbonate (taken from https://lifeinthefastlane.com). On this 12-lead ECG after administration of sodium bicarbonate you can see atrioventricular dissociation with normal QRS, normal axis, and resolution of tall R wave in AVR.
