Q

What is an Atrial Flutter

A

Occurs when rapid impulse originates in atrial tissue. Atria is not coordinated

17
Q

How to identify Atrial Flutter

A

Sawtooth pattern, F waves constant
Atrial rate: 250-350 bpm

18
Q

How to calculate atrial rate in an Atrial Flutter?

A

(Ventricular rate)×(number of Flutters per QRS complex)

19
Q

What is Atrial Fibrillation

A

A-Fib
Occurs when electrical impulses come from areas of multiple ectopic foci. Whole atrium quivers

20
Q

What is Atrial Fibrillation

A

A-Fib
Occurs when electrical impulses come from areas of multiple ectopic foci. Whole atrium quivers

21
Q

How to identify Atrial Fibrillation

A

Chaotic atrial electrical activity
Irregular R-R intervals

22
Q

What is dangerous about A-Fib?

A

Blood clots are prone to forming in the atria and can travel which can block blood from going to places

23
Q

A patient with AFib is at an increased risk of developing?

A

Cerebrovascular Accident (CVA or Stroke)
Myocardial Infarction (heart attack)
Pulmonary embolism (PE)
Renal Infarction
