What are the s/sx of 3rd degree heart block (complete)? - ANSWER-light-headedness, dizziness, fainting, fatigue, chest pain, bradycardia
ventricles fire own impulse (wide and wacky), atrial and ventricular rates are independently regular, atrial rate = 60-100, ventricular rate = 20-40, p waves are normal but not related to QRS, no PRI due to dissociation, QRS depends on level of escape rhythm
What is the treatment for 3rd degree heart block? - ANSWER- Call for help
