The lack of oxygen to the heart, which is common in the condition known as myocardial ischemia, can cause the organ to completely shut down or become damaged. Early detection is necessary in order to prevent fatal results.

Effects And Causes Of Lack Of Oxygen To The Heart
What happens when there is a lack of oxygen to the heart muscle?
- The heart might completely shut down from lack of oxygen.
- The heart muscle could become damaged, and its ability to pump blood efficiently will be diminished.
- The muscular tissues of the heart could become necrotized.
- Death is also possible.
Causes Of Lack Of Oxygen To Heart Muscle
- Ventricular tachycardia, a condition where the heart gives sudden, irregular beats that cause the organ to function incorrectly
- The narrowing of arteries (also known as atherosclerosis), which commonly occurs in the elderly
- Congenital heart defects
- Exceedingly low blood pressure (as what happens during a heart attack)
- Blood clots (which can lead to heart attack)
Symptoms And Treatment Of Lack Of Oxygen
- The person might complain of chest pains, usually on the left side of the body.
- Pain in the jaw
- Cold or clammy skin
- The person might experience shortness of breath.
- Arm or shoulder pain
- Feeling nauseous or outright vomiting
Treatment Of Low Oxygen Levels
- Treatment methods aim to improve blood flow to the heart.
- Physicians may prescribe medications for thinning the blood.
- Surgical procedures might also be necessary in order to clear blockages in arteries, thus widening the passages for blood.
- Dietary restrictions might be recommended for individuals diagnosed as having high cholesterol levels.
- A cardiovascular exercise regimen can help improve blood flow to the heart and strengthen heart muscle.
- Stress reduction is encouraged.

My theory: I have a Vagus Nerve Entrapment Causing Atrial Fibrillation with Tachycardia due to the reverse curve of my neck.
History:
I occasionally get A-fib with tachycardia – an irregular heartbeat with an increased heart rate. I believe these episodes are caused by a Vagus nerve entrapment. I started having episodes in my mid to late twenties. The medical diagnosis was that it was caused by a hyperactive thyroid. At the time, my entire metabolism was haywire. I was burning over 5000 calories a day at rest, not including exercise (measured through resting and active VO2 testing) and had lost over 20 pounds in less than two months. I would experience A-fib episodes that lasted 5-8 days (day and night).
Heart Of Vegas Problems
Over the years, my thyroid has returned to normal function, but I continue to have A-fib episodes, although much briefer in duration (a few to less than 24 hours). I’ve seen endocrinologists and cardiologists. They don’t know the root cause and the only solutions they have been able to offer are either pharmaceutical drugs or surgery (ie pacemaker). I tried drugs. The side effects were untenable and I’m not willing to have invasive heart surgery when the doctors really don’t understand the cause of the condition. I’ve witnessed way too many people have these types of surgeries which either didn’t solve the “problem” and often made things worse.
These episodes are not comfortable. My nervous and cardiovascular systems are in a state of overload and stress. My heart is working 25-35% harder at everything I do. It basically feels like I’m running… when I’m sitting, lying down, and sleeping. Physiologically it feels like I’m having an anxiety or panic attack. Any kind of physical activity, such as climbing stairs or working out, immediately leaves me breathless and occasionally dizzy.
I also have a posterior or reverse curve to my cervical spine (as seen on x-rays). The cervical spine should have an anterior curve. This is a significant structural adaptation that has more than likely developed from my extensive injury history – concussions, whiplash injuries from multiple car and motorcycle accidents, knee surgeries, and many other injuries.
Vagus Nerve (a very rough overview)
The Vagus nerve (CN X) is a cranial nerve that is directly linked to the parasympathetic nervous system, playing a role in heart rate, respiration, and digestion. The Vagus nerve helps to down-regulate or slow down heart rate after the body goes through a sympathetic “fight or flight” response – ie the massive adrenaline rush after a scary situation. In our modern world, most of us are in a constant state of stress creating a low-level “fight or flight” response. The sympathetic and parasympathetic nervous systems are constantly interacting with one another to maintain some semblance of homeostasis or balance.
The Vagus nerve originates in the brainstem, traveling down through the neck (external to the spinal cord and spine). Since it travels outside the spinal cord, it is exposed to potential muscular, fascial, or structural entrapment.
My Theory
Due to the reverse curve in my neck, any kind of excess tension or restrictions in the muscle/fascia or vertebral position of the cervical region can occasionally entrap the Vagus nerve. If the Vagus nerve becomes entrapped, the electrical signals between the brain and heart (or respiratory and digestive systems) can become inhibited – ie experience some loss of signal. This loss of signal affects the balance between the conversation of sympathetic and parasympathetic related to heart rate and can cause heart rhythm irregularities. In my case, less signal to downregulate the heart rate which leads to an increased heart rate and arrhythmia.
Movement Session
Today, I am experiencing an episode of A-fib with tachycardia. There is also tension/restriction in my neck related to specific movement patterns. My focus of this session is to improve neck and spinal mobility through the combination of self-massage (using a Thera-cane and lacrosse ball) and Movement Therapy to free the Vagus nerve from entrapment. The past few times I’ve had an episode, this combination seemed to help resolve the arrhythmia pretty quickly.
Heart Of Vegas Troubleshooting
When searching for the underlying root cause of a “problem”, it is easy to get into a game of the chicken or the egg. The “problem” is rarely ever found with just one simple solution. The human body is a complex system of complex systems. Each system is intricately connected to one another in a constant feedback loop. When one system isn’t working properly, it affects change and can cause other systems to stop working properly, which then feeds back into the larger system, wreaking havoc. This is just one theory that I am playing around with in my movement practice.
