Sotalol -> QT prolongation and TdP
What's the QRS (wide = 3-4 amps bicarb)?
Hows their contractility (decreased = glucagon 10 mg, 1 unit/kg insulin w/D50)?
How's SVR (pressors)?
What's the rate (brady = glucagon 1- mg, levophed, pacing)? |

TCA Tox
QRS > 100 ms in lead 2, R' in aVR, usually sinus tachTwo main adverse effects -> seizures QRS > 120 and ventricular arrythmias (QRS > 160)
Serum alkalinization -> Hyperventilate to pH of 7.5ish, NGT for charcoal, Tx seizures with benzos, Bicarb drip = D5W, 40 meQ of K, 3 amps Na Bicarb, 2 x maintenance, 1...
Causes include: Sodium channel blockade is seen in TCAs, Antiarrhythmics, Local anaesthetics, antimalarials, propranolol, Carbamazepine, Quinine |

3rd degree heart block
Atrial rate is ~ 85 bpm.
Ventricular rate is ~ 38 bpm.
None of the atrial impulses appear to be conducted to the ventricles.
Rhythm is maintained by a junctional escape rhythm.
Marked inferior ST elevation indicates that the cause is an inferior STEMI.
Tx: Place pacer pads, Unstable = Atropine unless QRS is wide |
