25
What are Beta-blockers ?
reduce nerve impulses to the heart and blood vessels | -(LOWERS BLOOD PRESSURE)
26
WHat are ACE inhibitors (ACE) ?
- inhibitors prevent the formation of a hormone called angiotensin II, which normally causes blood vessels to narrow. The ACE inhibitors cause the vessels to relax - LOWERS BLOOD PRESSURE
27
What are Calcium channel blockers (CCBs) ?
keep calcium from entering the muscle cells of the heart and blood vessels. This causes the blood vessels to relax - LOWERS BLOOD PRESSURE
28
What is a Pulse oximetry ? | attached to patients finger/ear lobe
non-invasive method of monitoring the percentage of haemoglobin (Hb) which is saturated with oxygen.
29
What are Some Cardiac Evaluation Tools? (6)
1. History 2. Heart rate, pulse and blood pressure 3. Auscultation 4. Laboratory tests i.e. Chest Xrays EKG, cholesterol, echocardiogram 5. Cardiac Stress Testing: Maximal, Sub Maximal 6. Fitness Testing
30
What is Auscultation?
heart reveals the normal audible (HEARING) cardiac cycle, which allows the clinician to assess heart rate, rhythm, and regularity
31
What is CAD: Coronary Artery Disease? (most common type of heart disease)
occlusion (closing of) of coronary artery leads to an inadequate oxygenation of an area of the heart and leads to a heart attack -angina is a symptom (pain in chest)
32
What is angina?
(pain) usually a symptom of CAD; a symptom of an underlying heart problem
33
Stable angina:
KNOWN: can go away with medication | *chest pain during activity or stress*
34
Unstable angina
UNKNOWN: (more serious) warning sign of an impending heart attack *chest pain at rest*
35
What is the most comomon congenital heart defect?
``` Ventriculoseptal defect (VSD) *hole in heart* ```
36
3 tyes of Valve disease?
1. Incompetence: poorly functioning 2. Stenosis: narrowing 3. Valve disease: can affect either the Mitral or Aortic valves
37
What is Mitral Valve Prolapse ?
displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole (contraction)
38
___ refers to an enlarged heart due to hypertrophy by overwork
Cardiomegaly
39
Cor Pulmonale?
enlargement of right side of heart is due to high blood pressure in the pulmonary blood vessels, usually caused by CHRONIC LUNG disease
40
Congestive Heart Failure (CHF) symptoms?
heart can't pump enough blood to the body's other organs. --most common signs: swollen legs/ ankles or difficulty breathing.
41
What is a Coronary Artery Bypass Surgery ?
a procedure to bypass a blocked section of a coronary artery and to deliver oxygen to the heart
42
Median Sternotomy?
incision into the sternum
43
**What are 6 Sternal Precautions (after incision) ? Precautions: for 8 – 12 weeks.
1. Avoid reaching behind you 2. Avoid reaching out to your side: this does NOT include using grab bars in the bath tub. 3. Avoid stretching your arms above your head. 4. Avoid heavy lifting (anything over 5 lbs). 5. Avoid pushing or pulling more than 5 lbs,. 6. Remember, two hands are better than one.
44
What is the Bruce Protocol? | Sub maximal Cardiac Stress Test
At each "stage" of exercise, the pulse, blood pressure and ECG are recorded, along with any symptoms the patient may be experiencing
45
A drop of less than ____ beats per minute after maximal exercise has been correlated with a significant increase in mortality*. Healthy Rate Recovery? (HRR)
12 | Normal range: 20 BPM
46
**Heart Rate Reserve (HRR) Calculations:
HRmax-HRest (220-18) - (60)= 142 difference between a person's resting heart rate and maximum heart rate
47
Astrand Cycle Ergometer's Validity: | correlation to VO2max approximately _____
0. 85-0.9 (very close) - pedal cycle ergometer at a constant workload: HR measured every minute, and the steady state heart rate is then looked up on published tables to determine an estimation of VO2max.
48
VO2 max?
maximum amount of oxygen in milliliters, one can use in one minute per kilogram of body weight
49
How can you increase your VO2 max?
work out that raises your heart rate for at least 20 minutes 3/week to raise your HR between 65-85% ex.- job 3/day
50
Several factors to be monitoring during CV exercise (5)
- Medical status of the patient - Contraindications for exercise - Orthopedic conditions - Pulse rate - Respiratory rate
51
What is Borg Perceived Exertion Scale?
how hard you feel like your body is working during physical acitivity -a person's exertion rating may provide a fairly good estimate of the actual heart rate during physical activity -increase: HR, breathing, sweating, etc.
52
**What is Target Heart Rate? | How do you calculate it ?
desired range of heart rate reached during Aerobic exercise which enables one's heart and lungs to receive the most benefit from a workout in a safe way -calculate by using a range of 50%–85% intensity
53
**Calculations for Simple THR?
THR = HRmax × %Intensity | ex. 202 x .50= 101
54
What is the Karvone Method ( similar to simple THR calculations) ? *its more accurate because it takes into account HRest (if its abnormally high or low)
THR = ((HRmax – HRrest) × %Intensity) + HRrest
55
When are "Fats mostly burnt? in which "Zone"?
Fitness Zone; 60-70 % max. HR
56
(DONT KNOW IF NEEDED) What are the 4 types of "Zones? plus %
1. Cardiovascular Training Zones 2. Healthy Heart Zone (Warm up: 50-60%) 3. Fitness Zone (Fat Burning: 60-70%) 4. Aerobic Zone (Endurance Training: 70–80% ) 5. Anaerobic Zone (Performance Training:80–90% ) 6. Red Line (Maximum Effort 90-100%)
57
What is Mediastinum?
Space between the lungs which contains the heart, the aorta, and vena cava
58
What is Percardium?
visceral layer that encloses the heart
59
What is the Cardiac Stress Test used for?
to evaluate the heart and vascular system during Exercise or Load; used in diagnosis of Coronary Artery Disease (CAD)
60
What is the Submaximal Cardiac Stress Test?
patient exercises only until a predetermined level of exercise is attained (used in patients with KNOWN Coronary Artery Disease)
61
What are the advantages of Astrand Cycle Ergometer?
simple test, mostly accurate and appropriate for ECG monitoring during exercises
62
What are the Disadvantages of Astrand Cycle Ergometer?
may underestimate the fitness of those with a high maximum heart rate -and overestimate fitness with advancing age (as max HR reduces with age)
63
WHat is the MET (metabolic equivalent) ?
the energy (oxygen) used by the body as you sit quietly, perhaps while talking on the phone or reading a book.
64
Medication that lowers blood pressure
A-B-C-D Ace-inhibitor Beta blockers Calcium Diaretics
