Resting ECG
Used to determine if arrythmias are present
Used to assess HR General assessment

Electrocardiogram (ECG)
Records the heart's electrical activity and monitors cardiac changes
The P wave—atrial depolarization
The QRS complex—ventricular depolarization and atrial repolarization
The T wave—ventricular repolarization

BP
The three most important variables affecting BP– 1. Stroke Volume– 2. Total Peripheral Resistance– 3. Heart Rate
– BP= HR x SV x TPR
![Page 7: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/7.jpg)
BP
A measure of the pressure exerted by the blood on the arteries– systolic BP - the pressure in the arteries
during systole (the contractile phase of the cardiac cycle)
– diastolic BP - the pressure in the arteries during diastole (the relaxation phase of the cardiac cycle)
![Page 8: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/8.jpg)
Cardiac Cycle
Events that occur between two consecutive heartbeats (systole to systole)
Diastole—relaxation phase during which the chambers fill with blood (T wave to QRS)
Systole—contraction phase during which the chambers expel blood (QRS to T wave)
![Page 9: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/9.jpg)
Cardiac Cycle
A. Systole– 1. Isovolumetric (no change in volume)
Contraction• ventricles are excited and begin to contract (no
blood moving)• valves are closed• ventricular P is
![Page 10: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/10.jpg)
Cardiac Cycle
Systole (cont.)– 2. Ejection
• when P in vent>aorta (~120mmHg)• semilunar valves open• blood ejected from ventricles into aorta and
pulmonary artery

Cardiac Cycle
B. Diastole– 1. Isovolumetric Relaxation
• ventricles are relaxed• semilunar valves closed• ventricular P is • atrial P<vent P• vent P<aorta P

Cardiac Cycle
Diastole (cont.)– 2. Filling
• AV valves open• blood flows into vent• vent P<atrial P

Methods of Assessing BP
Auscultation using a stethoscope and sphygmomanometer– 1. Seated for at least 5 minutes with arm
the level of the heart (no caffeine or smoking 30 min prior)
– 2. Align cuff with brachial artery (the bladder should encircle 80% of an adults arm and 100% of a child’s arm)
![Page 16: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/16.jpg)
Methods of Assessing BP
– 3. Place stethoscope bell over the brachial artery beneath the cuff
– 4. Inflate cuff quickly to 20 mmHg above estimated systolic
– 5. Slowly release valve (2-3mmHg/s) noting first Korotkoff sound)
![Page 17: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/17.jpg)
Methods of Assessing BP
– 6. Continue releasing until sound becomes muffled (4th) and then disappears (5th)
– 7. Wait 30s and repeat (use the average)
![Page 18: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/18.jpg)
What causes the sounds you here?
![Page 19: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/19.jpg)
BP Sounds
The sound of blood moving through the vessels is normally silent.
Smooth laminar blood flow - blood in center of vessels moves faster than blood closest to vessel walls (produces little sound)
![Page 20: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/20.jpg)
BP Sounds
Pinching the artery causes turbulence and is noisy
The tendency of the cuff pressure to constrict the artery is opposed by blood pressure
If cuff pressure is greater than systolic pressure the artery is completely constricted and no sounds are heard.
![Page 21: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/21.jpg)
BP Sounds
When pressure is released from the cuff the first sound you hear (1st Kortokoff sound) is when the cuff pressure reaches the systolic pressure
Blood is passing turbulently as the artery becomes unconstricted
![Page 22: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/22.jpg)
BP Sounds
You continue to hear sounds at every systole (contraction of the heart) as long as the cuff pressure remains above diastolic pressure
When sound becomes muffled is called the 4th Kortokoff sound (7-10 mmHg higher than 5th Kortokoff sound)
![Page 23: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/23.jpg)
BP Sounds
When cuff pressure reaches diastolic pressure the sounds disappear (5th Kortokoff sound) since the artery opens and laminar blood flow begins
Use 5th sound as an index of diastolic pressure
![Page 24: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/24.jpg)
Heart Rate Assessment
Classifications for Exercise
![Page 25: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/25.jpg)
HR Assessment
Methods– Auscultation - using stethoscope, count
beats for 30-60 seconds– Palpation - at brachial, carotid, radial, or
temporal artery– Heart Rate Monitors– ECG
![Page 26: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/26.jpg)
Palpation
Use tips of index and middle fingers (not the thumb)
Don’t apply heavy pressure to carotid (baroreceptors will slow the heart)
Count beats for 6 (x10), 10 (x6), 15 (x4), 30 (x2), or 60 second (6 and 10 when exercising or immediately post-exercise; 15, 30, 60 for resting)
![Page 27: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/27.jpg)
Assessing Cholesterol
Classifications for Exercise
![Page 28: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/28.jpg)
Fats/Cholesterol
Fats = triglycerides and cholesterol Cholesterol = fat-like substance found in
foods of animal origin Triglycerides = three fatty acids
attached to a glycerol molecule– saturated or unsaturated
![Page 29: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/29.jpg)
Lipoproteins
Transport fat-like substances (cholesterol/triglycerides) through the blood– Very Low Density Lipoproteins (VLDL) -
major carrier of triglycerides– Low Density Lipoproteins (LDL) - major
carrier of cholesterol deposited on artery walls.
![Page 30: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/30.jpg)
Lipoproteins
– High Density Lipoproteins (HDL) - carry cholesterol to liver to be disposed of
![Page 31: Initial Resting Assessments Blood Pressure, Heart Rate, Cholesterol.](https://reader030.fdocuments.in/reader030/viewer/2022032722/56649ce45503460f949b02cb/html5/thumbnails/31.jpg)
