orthostatic

1 There’s orthostatic intolerance, for one — which, as one scientist pointed out to me, can’t be “psychological.”

2 He said that while orthostatic hypotension is commonly regarded as a neurological problem, “it’s associated with a lot of subclinical cardiovascular pathology, which is probably the largest contributor.”

3 National Institute of Neurological Disorders and Stroke has more on orthostatic hypotension.

4 About 54 percent of participants with delayed orthostatic hypotension wound up progressing to OH within a decade, the investigators found.

5 The second underlying cause of orthostatic hypotension is autonomic failure.

6 In particular, orthostatic hypotension, which is a reduction in blood flow to the brain caused by moving from lying down to standing or sitting, can lead to dizziness and increased risk of a fall.

7 There are two basic reasons that orthostatic hypotension can occur.

8 Others report what is known as orthostatic intolerance, meaning they might develop worsening symptoms when they change positions, such as sitting down or standing up.

9 About 180,000 patients suffer from the blood pressure drop Northera aims to treat known as neurogenic orthostatic hypotension in the U.S.,

10 Reports in 2006 said Page had been diagnosed with orthostatic intolerance, an illness related to blood pressure.

11 Objective To study structure of the unstable periodic orbits (UPOs) of R-R interval signals of heart during orthostatic standing, and to reveal the dynamic characters of heart rate variability (HRV).

目的研究立位心脏R- R间期信号的非稳定周期轨道的结构，进一步探讨心率变异（HRV）的动力学特征。

12 The cardiovascular system (CVS) response to orthostatic or gravitational stresses shows the function of cardiovascular regulation.

立位应激或不同重力应激下心血管系统(CVS)的反应，是CVS调节功能的重要表现。

13 According to the researchers, it's long been known that orthostatic hypotension can cause brief episodes of reduced blood flow to the brain.

14 While in the Chinese herb-compound group, the heart rate of the rabbits kept smooth, ischemic changes in ECG were not clear, and orthostatic tolerance time increased.

而中药组兔心率平稳，心电图缺血性改变不明显，立位耐受时间增加。

15 He has been diagnosed with a loss of white blood cells and an autonomic disorder called postural orthostatic tachycardia syndrome, which affects his ability to regulate blood pressure.

16 The name for this is orthostatic hypotension, which means that blood pressure goes below the homeostatic set point when standing.

17 Another cited problem was a condition called "postural orthostatic hypotension," in which blood pressure drops suddenly when a person stands up after sitting or lying down.

18 The 10-year death rate for people who started out with delayed orthostatic hypotension was 29 percent, the study said.

19 Dr. Rowe determined that Chris has the heart-racing condition known as postural orthostatic tachycardia syndrome, or POTS, which can occur after viral infections and limits the ability to carry out day-to-day activities.

20 In addition to complex pediatric long Covid, Ayden had been diagnosed with orthostatic intolerance, an inability to remain upright without symptoms like lightheadedness, and dysautonomia, a dysfunction of the nerves that regulate involuntary body functions like heart rate and blood pressure.
