Normal/Abnormal Responses

QuestionAnswer
What is the normal HR range? 60-100 bpm
Generally, what is the formula for max HR? 220-age
A HR below __ is considered abnormal. 40 bpm
CO is typically between how many L/min 4-6 L/min
A low HR can be a sign of what? blockage
Resting HR above __ bpm may be abnormal. 100
A pt that presents with the following may have what? Low Resting HR (50 – 70 bpm) Poor physical condition (untrained) Advanced 3-vessel disease Max HR limited by symptoms well below PMHR Males between ages of 40 – 60 CAD
If ones HR falls with increasing work load, what should you do? What could this be a sign of? STOP EXERCISE/CAD
What are the normal responses to exercise for the following? CO, Systolic BP, diastolic BP CO increases, systolic rises as workload increases, diastolic may increase, remain, or drop slightly
Well conditioned athletes may experience a _____ ______ in diastolic pressure when exercising. sharp drop
With increasing workloads, are responses of both systolic and diastolic BP normal or abnormal? What can this be a sign of? abnormal/pathology
Is a flat systolic response response to increasing workloads normal or abnormal? abnormal
Systolic begins low (110 mmHg) rises slightly, then begins to fall despite increased HR and workload...what might this be a sign of? post infarction
A drop in systolic BP w/ exercise is considered significant at what level? > 10mmHg and/or clinical signs such as SOB, development of 3rd heart sound
T or F. A drop in SBP w/o other abnormalities is OK. True...A flat or fall in systolic BP in middle-age women, or pts on beta-blockers not significant unless accompanied by other abnormalities.
Abnormal SBP response associated with SOB, ST depression or elevation, agina or pallor, 3rd heart sound could be signs of what? severe ischemia, poor ventricular function, or combination
Is a persistent rise in diastolic pressure w/increased exercise workload normal or abnormal? What might this be a sign of? abnormal/increases severity of CAD
Diastolic Blood Pressure Abnormalities are defined as diastolic rise of __ mm Hg above __ mm Hg with increasing levels of exercise 20, 90
Chest discomfort caused by impaired blood supply to cardiac muscle is called what? Angina
What is the measurable point at which angina may occur and what is this formula? Rate Pressure Product(RPP), HRxSBP
Angina that recurs at a fixed RPP, is reproducible by eating, emotional distress, or exercise and is relieved by rest or nitroglycerin is what kind of angina? Chronic Stable Angina
What kind of angina is caused by vasospasm of the coronary artery? variant angina
What is another name for variant angina? Prinzmetal angina
What king of angina occurs at rest or may wake a patient at night? Unstable angina
Which type of angina is also called "preinfarction" angina? Why? unstable angina. It is an ominous symptom of impending MI.
Does chronic stable angina occur at lower or higher RPP's than unstable angina? usually lower
How many levels are used to rate angina? 4
What level of angina?....the initial perception of discomfort. Reflects a minimum level of discomfort. Level I
What level of angina?....initial discomfort has intensified over the same or relatively the same body surface area, or it has become referred discomfort that extends to another body surface area. Level II
What level of angina?....initial discomfort has become so severe that the pt stops whatever they are doing as seeks medicinal relief. Level III
What level of angina?....same severity of discomfort that the patient feels during a heart attack Level IV
