MindMap Gallery Atrial Fibrillation Concept Map
Atrial fibrillation is an irregular and often rapid heart rate that occurs when the two upper chambers of your heart experience chaotic electrical signals.
Mind maps are a great resource to help you study. A mind map can take complex topics like plant kingdom and illustrate them into simple points, as shown above.
Mind maps are useful in constructing strategies. They provide the flexibility of being creative, along with the structure of a plan.
Vitamins and minerals are essential elements of a well-balanced meal plan. They help in ensuring that the body is properly nourished. A mind map can be used to map out the different vitamins a person requires.

EKG showing afib
no P wave, wavy baseline instead
Rapid heart rate
110 to 180 beats per minute
Complications

metoprolol orcarvedilol
calciumchannelblockers
diltiazem
Cardiacglycoside
Digoxin
PermanentPacemaker
Anticoagulation Management
CHADS2 score of 2 or more
Pradaxa or Coumadin
Rhythm Contorl
Antiarrhythmia medication
Tikosyn
must be hospitalized for initiation
Sotalol
Amiodarone
side effects
Hypothroidism
Pulmonary fibrosis
Flecainide
Propafenone
Ablation
Targeted/focal
return to NSR if successful
AV node
often symptom control, not rhythm control
destroys ability of AV node to send electricalimpulses
Permanent Pacemaker required
MAZEprocedure
incisionsmade on atria
Scar tissueforms
Abnormal electical impulsesdisrupted
Cardioversion
return to NSR is successful
starting dose 100 to 120 Joules
Diagnosis
Cardiac monitoring
Holter monitor
portable event monitor
EKG
Electrophysiologist/cardiologist consult
