(T/F) A healthy heart beats with a consistent rhythm
False
(T/F) A healthy heart does not beat with a consistent rhythm, but rather exhibits slight variations in the timing between successive heartbeats
True
HRV can be analyzed using what two tests?
1) electrocardiogram (ECG)
2) photoplethysmography (PPG)
(Higher/lower?) HRV is generally associated with better health outcomes, as it indicates a more adaptable and resilient cardiovascular system
Higher
(Higher/lower?) HRV has been associated with increased risk of various health conditions, including cardiovascular disease, diabetes, and mental health disorders
Lower/reduced
-a measure of the variation in time intervals between successive heartbeats, also known as R-R intervals, which are measured in milliseconds
-reflects the adaptability and responsiveness of the cardiovascular system to changes in internal and external stimuli
Heart rate variability (HRV)
If someone has a low HRV, what 4 things may this indicate? Just name which one this falls under
Sympathetic
"Fight or flight"
Easily exhausted
Low adaptability
Decreased cognition
If someone has a high HRV, what 4 things may this indicate? Just say which one this is
Parasympathetic
"Rest and digest"
Improved performance
High adaptability
Improved cognition
What 2 things are HRV considered to be an important indicator of?
Cardiovascular health
Overall well-being
a record of the electrical activity of the myocardium
electrocardiogram
Which line represents the ideal operational "balance" between the activity in the Sympathetic and Parasympathetic nervous systems?
Vertical centerline
Does sympathetic dominance plot to the left or right of the centerline?
Left
Does parasympathetic dominance plot to the left or right of the centerline?
Right
a simple low-cost optics technique that can be used to detect blood volume changes in the microvascular bed of tissue with each heartbeat
Photoplethysmography
Which line represents an average, calculated threshold for activity within the autonomic nervous system?
Horizontal line
Which zone is when the patient is highly sympathetic and has high amounts of adaptive reserve?
Zone 1
-zone where they are sympathetic dominant with low autonomic reserve
-further down and lower left they plot, the more incapable they are in managing their daily stress
Zone 3
Which zone does this describe?
Patients have very little adaptive reserve to respond to the demands of any stress, making them extremely vulnerable to environmental or pathogenic stressors
Zone 4
zone where the parasympathetic dominant state should be regarded as a sympathetic insufficiency response
Zone 2
What is one of the goals in managing zone 1 patients?
To reduce the excessive activity while regaining the parasympathetic control
Zone 2:
These patients classically have low ____________ function which suppresses the release of sympathetic neurotransmitters
Adrenal
What is zone 1 sometimes referred to as?
Zone 1
Which classroom are we taking the exam?
127/125
Which zone is considered the ideal target for remaining in a well-adjusted state; the higher a person plots in this zone, the greater responsiveness they have for managing stress and taking on more good stress
Zone 5
What time is the exam for Muscle Gait?
9:30am
