1. antihypertensive ËACE inhibitors, "pril"
drugs ËARBs, "sartan"
ËAlpha blockers, "osin"
ËBeta blockers, "lol"
ËCalcium channel blockers, "dipine"
ËDiuretics, "ide"
2. Beta Blockers "lol"
Beta blockers cause the heart to beat more slowly and with less force. This
lowers blood pressure. Beta blockers also help widen veins and arteries to
improve blood flow.
3. Calcium Channel "dipine"
Blockers Calcium channel blockers are medicines used to lower blood pressure. They
stop calcium from entering the cells of the heart and arteries. Calcium causes
the heart and arteries to squeeze more strongly. By blocking calcium, calcium
channel blockers allow blood vessels to relax and open.
Some calcium channel blockers also can slow the heart rate
4. Digoxin used to improve the strength and efficiency of the heart, or to control the rate
and rhythm of the heartbeat.
5. Amiodarone antiarrhythmic
It works directly on the heart tissue and will slow the nerve impulses in the
heart. This helps keep your heart rhythm normal.
It is used to treat life-threatening heart rhythm problems called ventricular
arrhythmias
6. atrial fibrillation rapid, random, ineffective contractions of the atrium
HR: 350-650, slow to rapid
rhythm: irregular
No P wave
QRS: <.12 seconds

7. atrial fibrillation risk Increasing age
factors Hypertension
Diabetes
Obesity
Valvular heart disease
Heart failure
Obstructive sleep apnea
Alcohol abuse
Hyperthyroidism
MI
Smoking
Exercise
Cardiothoracic surgery
Family History
8. atrial fibrillation Quivering atria
complications "Fibbing of the P waves"
Heart failure due to backup
Myocardial ischemia bc of clot
Embolic events like stroke bc of clot
Pulmonary embolism bc of clot
- Rapid & irregular ventricular response = reduced ventricular filling = smaller
stroke volume
9. atrial fibrillation some asymptomatic
manifestations palpitations
SOB
dyspnea, dyspnea on exertion,
hypotension
lightheaded

tachycardia
fatigue
pulse deficit (numeric difference btw apical & radial pulse rates)
10. atrial fibrillation - antithrombotic meds: anticoagulant to prevent atrial clots, antiplatelet
pharmacotherapy - control HR: BB (-olol), CCB (-dipine)
- control heart rhythm: amiodarone, dofetilide (metoprolol, digoxin)
11. atrial fibrillation - synchronized cardioversion (anticoagulant admin. before)
treatments - catheter ablation therapy
12. synchronized car- the passage of an electric current through the heart during a specific part of
dioversion the cardiac cycle to terminate certain kinds of dysrhythmias
Synchronized shock
13. catheter ablation Sound waves or cold temperatures are passed through catheter placed at or
therapy near origin of arrhythmia, causing thermal injury, localized cell description
destruction, & scarring
14. Atrial Fibrillation: In- Administer oxygen.
terventions Administer anticoagulants as prescribed because of the risk of emboli.
Administer cardiac medications as prescribed to control the ventricular
rhythm and assist in the maintenance of cardiac output.

Prepare the client for cardioversion as prescribed.
Instruct the client in the use of medications as prescribed to control the
dysrhythmia
15. ventricular tachy- a life-threatening arrhythmia in which the ventricles, rather than the SA node,
cardia initiate the heartbeat; the heart rate is between 150 and 250 bpm
16. ventricular tachy- ventricular fibrillation and death
cardia complica-
tions
17. ventricular tachy- - assess client (PULSE)
cardia treatment - vital signs
- antiarrhythmic medications IV drip: procainamide, amiodarone, lidocaine
