1、心脏康复评定A PATIENT CASE EXAMPLE 1.Why are you here today?2.Have you been diagnosed with a cardiac disorder in the past?3.Have you had any special tests to examine your heart like an electrocardiogram,stress test,echocardiogram,or cardiac catheterization?4.Do you experience angina or shortness of breath

2、 at rest,only with activity/exercise,or both at rest and with activity/exercise?5.If you experience angina or become short of breath during activity or exercise could you please describe the type of activity or exercise which produces your angina or shortness of breath?6.Can you describe your angina

3、 or shortness of breath?Can you help me understand your angina or shortness of breath by pointing to the numbers 1 through 4 to describe the level of angina you experience at rest and exercise or by pointing to your level of shortness of breath using this 10-point scale or by marking this visual ana

4、log scale?7.Could I feel your pulse to determine your heart rate and the strength of your pulse?8.Could I place this finger probe on your index finger to obtain an oxygen saturation measurement?9.Could I place these electrodes on your chest to obtain a simple single-lead electrocardiogram(ECG)?10.Co

5、uld I take your blood pressure while you are seated and then compare it to the blood pressure while you are lying down and then standing?I would also like to observe your pulse,oxygen saturation,ECG,and symptoms when you are lying down and standing.11.Could I listen to your heart and lungs with my s

6、tethoscope?While I do this I will concentrate on watching your ECG so that I can identify your heart sounds and any changes in the ECG while you are breathing deeply when listening to your lungs.12.Could I place 1 of my hands on your stomach and 1 hand on your upper chest to determine how you breath

7、e?13.Could I place my hands on the lowermost ribs on each side of your chest to determine how you breathe?14.Could I place my hands on your back to determine how you breathe?15.Could I wrap my tape measure around your chest at several different sites to determine how you breathe?16.Now that I unders

8、tand some very basic information about the manner in which you breathe could you please breathe in the manner I instruct you via sounds I make,pressure from my hands,methods I show to you,or different body positions?I will occasionally place my hands on your chest and wrap my tape measure around you

9、r chest to determine how you breathe during these simple tests and I will ask you to identify your level of shortness of breath using the 10-point scale or visual analog scaleIs this ok with you?17.Could I measure the strength of your breathing muscle by having you place this mouthpiece in your mout

10、h and breathe in and out as deeply and as forcefully as you are able?18.I would like you to now perform the activity or exercise which produces your angina or shortness of breath.Could you please do this now?Thank you for giving me the chance to examine you today.I will call your physician to get so

11、me more information about you like electrocardiogram,echocardiogram and pulmonary function tests that you said were performed last week as well as the arterial blood gas results,chest X-ray,and exercise test results.Physical Therapy Examination Medical Information and Risk Factor Analysis listening

13、lpation in the painful area,or movement of a joint(ie,shoulder flexion and abduction)it is very likely that the pain is NOT angina.Angina-Methods To Evaluate Angina from Nonanginal Pain it can be worsened by physical exercise or activity.Therefore,if the suspected anginal pain is unchanged with the

14、previously cited maneuvers and the pain occurred with exertion,it is SUSPECT for angina.If the suspected anginal pain is unchanged by these maneuvers,if the pain occurred with exertion,and if the pain decreases or subsides with rest,it is very likely that the pain IS angina.Finally,if the suspected

15、pain decreases or subsides with nitroglycerin,it is even more likely that the pain IS angina.Other Symptoms of Heart Disease dyspnea Fatigue Dizziness Light headedness Palpitations a sense of impending doom Examinations of Patient Appearance skin color of the peripheral extremities.Pale or cyanotic

19、Body PositionsTo Determine the Status of the Cardiovascular System observation of a decrease in systolic and diastolic blood pressure without a subsequent increase in heart rate when changing body position from supine to standing is considered a positive sign for autonomic nervous system dysfunction

20、.To Determine theHealth of the Cardiovascular System A cardiovascular system that responds rapidly to body position change is likely in a better state of health than a cardiovascular system that responds sluggishly.Both an unchanged or decreased heart rate after standing for 30 seconds(compared to t

21、he heart rate at 15 seconds)is suggestive of autonomic dysfunction.a sluggish or hypoadaptive(less than normal)heart rate and blood pressure response during a change in body position supine to standing should be considered abnormal and suggestive of an unhealthy cardiovascular system.a more adaptive

22、 rapid increase in heart rate and blood pressure after moving from a supine to standing position(approximately 30 seconds)is likely associated with a healthier cardiovascular systemExamination of the Pulse and Arterial Blood PressureDuring Functional Tasks and Exercise Frequent monitoring of the hea
