Flashcards in Cardio arrhythmia Deck (22):
1

little box in ecg?

.04 seconds. One big box is .2 econds

2

1st degree heart block is what?

Tx?

Longer Pr. greater than 0.2 seconds (one big box)

No tx

3

2nd degree heart block type 1 is what?

Caused by what?

Wenckeback (w for warning). One-kebock (to remember it is mobitz type 1.

Progressively lengthening then dropped beat.

Caused by meds slowing heart rate. B blockers, dig, calcium channel blockers

Treatment not necessary unless symptomatic bradycardia. Otherwise not concerning

4

2nd degree type 2?

Randomly skipped without warning. Problem with av or bundle system

Can progress so often given pace maker

5

3rd degree heart block?

Hypotension. No P wave QRS symptoms

NEEDS PACING

6

What do you need pacing for?

2nd degree Mobitz II and 3rd degree

7

Supraventricular tachy tx?

Might see P waves in T waves. Might see delta wave in WPW

Carotid or valsalva
IV adenosine (tx and dx)
Calcium channel or beta blockers, cardioversion or ablation!

8

Multifocal atrial tachycardia ekg finding

EKG variable P wave morphology.

HR greater than 100

Tx: verapamil or dilt. Beta blockers. Correct magnesium and hypokalemia

Surgery like ablation

9

Endocrine cause of A fib you want to check?

HYPERTHYROIDISM!

10

A fib less than 48 hours? Tx

Cardioversion. If longer than that, don't convert b/c risk of thrombus. IF LONGER you can anticoagulant then cardiovert

11

Chronic a fib workup and quick tx

Anticoag and transesophageal echo

NEED HEPARIN BRIDGE!!!

12

Tx of chronic afib?

Rhythm control with amiodarone or sotalol

OR RATE control, with beta blocker or nondihydropyridine or dig

If staying in AFIB, need anticoag

13

Tx of a flutter?

Rate control with calcium channel blockers

Cardioversion
Catheter ablation if need be

CAREFUL can become afib

14

When are PVCs concerning?

more than 3 per minute or three in a row or more

Usually don't tx

15

Vtach tx?

Cardioversion. may need pacemaker if recurrent

16

Torsades tx?

IV PUSH!!!

17

Vfib tx?

shock the shit them. CPR first

18

Classes of antiarrhtymic mnemonic?

No Boy Keeps Clean

Na
Beta Blocker
Potassium
Calcium (ver and dilt)

19

Class 1 b drugs are what and used for what?

lidocaine and tocainide
used for v fib

20

Class 2

beta blockers used for

Rate control
Multifocal atrial tachycardia (basically protect the ventricles)

21

Class 3

Amiodarone, sotalol and bretylium

Rhythm control of fib and flutter

Amiodarone can cause thyroid and liver dysfucntion and fibrosis of lung

22

What is sotilol?

potassium blocker for rhythm control
