What do you do if there’s hemodynamics compromise
Sedate and shock
3 cardinal signs of hemodynamics compromise
Angina
Hypotension
Heart failure (pulmonary edema, rales)
Rate control drugs for a fib and a flutter
Beta blockers (metoprolol, esmolol)
Calcium channel blockers (diltiazem, verapamil)
Amiodarone
Digoxin
Why is diltiazem better than verapamil for rate control in a fib and flutter
Doesn’t lower BP as much
Less likely to worse HF
Don’t use beta blocker if
COPD
Asthma
Target heart rate for rate control drugs
<110
Ablation strategy for a fib and flutter rate control
Ablate AV node
Implant permanent pacemaker
What drugs are used for rhythm control
Dofetilide Dronedarone Flecainide Propafenone Sotalol
Ibutilide (acute)
Amiodarone (second line)
Only rhythm control drug you can use if have HF or other significant structural heart disease
Dofetilide
What rhythm control drugs can prolong QT interval
Dofetilide
Propafenone
Sotalol
Ibutilide (acute)
First line rhythm control if have HF
Amiodarone
Dofetilide
Ablation to treat a fib
Ablate pulmonary veins
Good candidate for rate control drugs
Young symptomatic patients with good rate control
Characteristics of accessory pathway tissue
Fast response (unlike AV node) Na channels (unlike AV node, which uses Ca)
A fib plus accessory pathway. What drug should you not give
AV blockade drugs like adenosine
A fib and accessory pathway. What drugs can you give
Procainamide
Ibutilide
Best option for patients with a fib and accessory pathway
Sedate and shock
What to do if have AV nodal reentry
Block AV node
What to do if have AV reentry with accessory pathway
Block AV node
Best drug for paroxysmal SVTs
Adenosine (if no asthma)
If person has paroxysmal SVTs and asthma, what can you give
Diltiazem
Verapamil
Have paroxysmal SVTs. What 2 options for chronic treatment
Ablation Drugs except class IB
If can’t tell what pt has on EKG, what drug can you give them
Adenosine
Adenosine side effects
Chest pain
Atrial and ventricular arrhythmias
Bronchospasm
