Labile hypertension occurs when there are unexpected changes in blood pressure.The term can be used to describe when people have blood pressure measurements that abruptly fluctuate from being abnormally high, approximately 140/90mm Hg or over and returns to its normal range.
[10] Ambulatory blood pressure monitoring and patient self-measurement using a home blood pressure monitoring device is being increasingly used to differentiate those with white coat hypertension or experiencing the white coat effect from those with chronic hypertension. This does not mean that these methods are without fault.
The difference between the systolic and diastolic pressures is known as pulse pressure, [1] while the average pressure during a cardiac cycle is known as mean arterial pressure. [2] Blood pressure is one of the vital signs—together with respiratory rate, heart rate, oxygen saturation, and body temperature—that healthcare professionals use ...
Familial dysautonomia (FD), also known as Riley–Day syndrome, is a rare, [2] progressive, [3] recessive genetic disorder of the autonomic nervous system [2] that affects the development and survival of sensory, sympathetic, and some parasympathetic neurons in the autonomic and sensory nervous system.
Hypertensive heart disease includes a number of complications of high blood pressure that affect the heart.While there are several definitions of hypertensive heart disease in the medical literature, [1] [2] [3] the term is most widely used in the context of the International Classification of Diseases (ICD) coding categories.
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Blood pressure is classified as normal blood pressure, prehypertension, hypertension (stages I and II), and isolated systolic hypertension, which is a common occurrence among the elderly. These readings are based on the average of seated blood pressure readings that were properly measured during 2 or more office visits.
Orthostatic hypotension (or postural hypotension) is a drop in blood pressure upon standing. One definition (AAFP) calls for a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within 3 minutes of standing. [31]
