100% Correct (Verified Solutions)
1. Cardiac conduction: what it does? generated by
what? travel through what? order of travel?: -Generate
impulses needed to initiate electrical chain of events to
cause heartbeat -Impulses generated by SA nodes
-Impulses travel through internodal pathways to depolarize atria
-Atria ’ AV node ’ bundle of his ’ bundle branches
2. Cardiac conduction summary: -P wave = Atria contracting
-QRS complex = Ventricles contracting (& atria repolarizing)
>Big one in the middle
>Getting ready for their next contraction *?
-T wave = Ventricles repolarizing
Getting ready to contract an additional time *?

3. Cardiovascular diagnostic tests: electrocardiogram (ECG):
•12-lead ECG
•Cardiac monitor
•Telemetry
•Holter monitor
4. Cardiovascular diagnostic tests: electrocardiogram (ECG) --
12-lead ECG: -Bedside machine
-Take quick and detailed snapshot of pt's heart rhythm at that specific
time
-12 leads all over chest, one on each leg, one on each arm
-Useful for diagnosing acute conditions
>*if pt has chest pain
>Heart attacks
>Arrhythmias
5. Cardiovascular diagnostic tests: electrocardiogram
(ECG) -- Cardiac monitor: -To continuously monitor
-Uses less leads

NUR 210
>Usually 5
>Needs at least 3 to get a rhythm
-See in ICU
-Can see rhythm on screen right at
bedside -Problem:
>Pt is bedbound
>Only used in hospital
6. Cardiovascular diagnostic tests: electrocardiogram
(ECG) -- Telemetry: -Use if pt wants to get up and move around
-5 leads
-Wire connect to little box that they carry with them
-Box sends info to other station
-Only used in hospital
7. Cardiovascular diagnostic tests: electrocardiogram (ECG) --
Holter monitor: -If pt doesn't need to be in hospital
-Similar to telemetry
-Can use at home (go anywhere they need to)
-Records rhythm for about 24-48 hours

-Pt should be writing down activities throughout the day
>Ex. you had palpitations when you went on run or when you drank
coffee
8. Cardiovascular Diagnostic Tests - Labs: •Troponin
•Creatinine Kinase MB (CK-MB)
•Myoglobin
•B-type natriuretic peptide (BNP)
Serum Lipids:
•High-Density Lipoprotein (HDL)
•Low-Density Lipoprotein (LDL)
•Triglycerides
9. Cardiovascular Diagnostic Tests - Labs: Troponin: -Gold
standard for detecting heart muscle damage specifically -Heart
attack will always have troponin order
-Levels high for awhile
