What is ischemic threshold?
The ischemic threshold was defined as the heart rate at which a 1 mm horizontal or downsloping ST segment depression appeared on a baseline treadmill symptom-limited exercise test.
What is anginal equivalent?
Anginal ‘equivalents’ (i.e., symptoms of myocardial ischaemia other than angina) such as breathlessness, faintness, fatigue, and belching have also been reported (Gersh et al 1997). A classic feature of stable angina is the disappearance of pain after the use of nitroglycerine or the inhalation of amyl nitrite.
What is RPP measured in?
Pressure rate product, also known as Cardiovascular Product or Double Product, is used in cardiology and exercise physiology to determine the myocardial workload. with the units for the Heart Rate being beats per minute and for the Blood Pressure mmHg….Rate pressure product.
| Hemodynamic Response | RPP |
|---|---|
| Low | 10000 – 14999 |
Is ischemia normal during exercise?
Previous studies and our findings In our study, we observed that painless myocardial ischemia during exercise was present in 10.7% of men. Ischemic ST depression in the absence of pain has been more common than ST depression with angina in daily life 20, 21, 22.
What is the normal range for peak RPP?
Rate Pressure Product (RPP) is a valuable marker of cardiac function.It is the product of heart rate (HR) and systolic blood pressure (SBP) (HR x SBP/1000). RPP up to 12 at rest and up to 22 in stressed conditions is considered as normal.
Why is blood pressure measured in both arms?
Atherosclerosis refers to a hardening and narrowing in the arteries that, eventually, could lead to heart disease or stroke. Measuring blood pressure in both arms gives doctors “a simple way of noticing possible arterial stiffening,” said Dr.
What is exercise induced ischemia?
One mechanism for silent myocardial ischemia after exercise is the rapid decline in diastolic blood pressure during recovery, which reduces the myocardial perfusion pressure gradient and transiently impairs subendocardial blood flow 29, 31.
What is a positive stress test for ischemia?
Positive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemia—meaning the heart muscle wasn’t getting adequate oxygenated blood during the stress. There are certain ECG and imaging changes that would support this conclusion. There are also clinical findings that could support it.
Should I worry about angina?
When to see a doctor If your chest pain lasts longer than a few minutes and doesn’t go away when you rest or take your angina medications, it may be a sign you’re having a heart attack. Call 911 or emergency medical help.
