used to stop av nodal reentry, terminates SVT, will cause brief period of asystole after dose. must give quickly, large bore IV, 6mg, flush, raise arm. follow with 2nd & 3rd dose of 12mg, max dose 30 mg
Calcium channel blockers used for hypertension or SV tachycardia (Type 4). Systemic vasodilator, prolongs AV nodal conduction time. Contraindicated with Beta Blockers. Give slowly (BP will drop). 5-10 mg IV q 15-30 minutes. 30 mg max dose
Main drug used in cardiac arrest, increases the likelihood of successful defibrillation. neurotransmitter
stimulates beta 1 & beta 2 adrenergic receptors (increases cardiac HR)
stimulates aplha 1
causes vasoconstriction (increases blood flow to heart muscle) 1 mg q 3-5 minutes
One time dose of 40 units IV for v fib/ pulseless v tachy; wait 20 min before giving another drug, may replace either 1st or 2nd dose of epi
• For PEA or asystole: 1 mg IV/IO Q 3 - 5 min
• Max: 3 doses or 3 mg
• 2 - 2.5 mg endotracheal if IV/IO not accessible
• Limited beneficial effects (asystolic arrest almost
Increases HR in bradycardia's and high degree AV nodal block.
• Relative safety of use, ease of administration, low
cost, theoretical advantages
most commonly used, V-Fib, V-tachycardia, A-Fib, A-flutter, cardiac resucitation. can be given once following epi or vasopressin if defibrillation is unsuccessful. also of potential value if VT or VF reoccurs following successful defibrillation.
