Vital Signs, Biomarkers, Oxyhemoglobin and Carboxyhemoglobin
Vital signs are signs of life that guide doctors as they take care of patients. The original signs of temperature, pulse, and respiration provide snap shots of human physiology that are worth thousands of words.
Modern computerized vital signs include holter electrocardiogram (ECG), pulse oximeter, capnogram, and acoustic respiration. These record videos of human physiology, which are worth millions of words; and they unlock the mysteries of covariant pathology (disease) such as the tachy brady rhythm of the sick sinus syndrome.
Biomarkers are part of vital signs that change during illness. For example, carboxyhemoglobin, which is carbon monoxide in blood, increases during abnormal anaerobic metabolism that produces metabolic acidosis.
Carboxyhemoglobin (SpCO) is a circulating biomarker that increases in the extremities of patients with DVT or neuropathy.
This website focuses on blood clots. Clots first develop as DVT (deep vein thrombosis) inside muscles and cause inflammation. Next they migrate into the heart as VTE (venous thromboembolism), which causes palpitations with premature heartbeats and dizzy spells. Finally, clots stop in the lungs as PE (pulmonary embolism), where they interfere with breathing.
Leonardo da Vinci: focus on the Gestalt
Blood clots are natural glue made by our body to stop bleeding from injured blood vessels. Without bloody glue, we would bleed to death when we cut our skin. Cancer or infections cause blood clots. Bad circulation or obesity cause blood clots. Sometimes pieces of blood clots break loose from sore veins and migrate into the heart, which cause palpitations with premature beats of the heart.
Blood Clots and the Pulmonary Valve: PVC & skipped beats
Leonardo believed in taking time to focus his attention and use his imagination. Venous blood clots have many effects, but none are as important as those when clots pass through the pulmonary valve. The pulmonary valve has three leaflets. Imagine what goes on inside the heart when an elongated tubular clot (VTE) moves into the valve. Visualize the buildup of pressure inside the right ventricular outflow tract (RVOT) as the nose of a blood clot reduces blood flow through the valve. Suddenly the pressure in the RVOT triggers a protective heartbeat called PVC (premature ventricular contraction) that prevents dangerous stretching of the ventricle that causes sudden fatal fibrillation. PVC is a protective reflex that helps the heart avoid sudden death!
How Does A Healthy Heart Respond to Blood Clots? What happens to breathing?
What happens when a big ball of soft glue migrates into a muscular heart pump that narrows down into the pulmonary valve? Blood clots go in and out of the pulmonary valve which pound the ball like a tiny three sided jackhammer. The valve pulverizes clots into pieces of sticky purple gel. Blood clots cause flip-flop palpitations and skipped beats as the move through the heart; and later, liquid bloody debris moves to the lungs, where it causes wheezing, difficulty breathing and panic attacks.
Premature Ventricular Contractions: Pulsus Interruptus
What happens during 130 milliseconds when a torpedo-shaped sticky purple blood clot passes in and out of the pulmonary valve?
Blood clots enter the valve and the nose of the clot narrows the opening. A small clot has a big effect on blood flow through the valve. A 20% reduction of the valve size reduces blood flow by 50%, which causes a premature increase of pressure inside the outflow tract. Myofibrils in the outflow tract of the right ventricle (RVOT) contain intrinsic pacemaker cells, which become excited when they are stretched. 'Ectopic' pacemaker cells in the RVOT start premature protective ventricular contractions.
A premature right ventricular contraction causes the valve to close and grip the nose of the clot, which causes the right ventricle to develop a rotating isometric contraction that tears open the neck of the clot.
The right ventricle is intimately connected to the left ventricle by a common wall, and blood clots in the pulmonary valve prevent BOTH right and left ventricles from contracting. The right ventricle dilates as the left ventricle partly decompresses and the heart skips a pulse as it contracts without pumping (pulsus interruptus).
After the clot passes through the pulmonary valve, the right ventricle decompresses and pumps a increased volume; and the heart flops back to the right as both ventricles empty. Clots cause PVC with flip-flop palpitaions and skipped heartbeats.
Think about how the parts are connected and take time to use your imagination
- Small blood clots cause the heart to skip one beat.
- Elongated clots cause the heart to skip every other beat.
- Clots cause flip-flop palpitations as they pass through the pulmonary valve.
- Large clots cause the heart to skip consecutive beats.
- Short runs of consecutive skipped beats lead to fainting spells.
- Long runs of skipped beats precede and lead to unconscious anoxic convulsions.
- Unconscious seizures perform self-CPR.
- Tonic clonic contractions by the arms and legs pump extra blood into the right ventricle.
- Convulsions (seizures) expel clots that obstruct the pulmonary valve.
- CPR performs the 'Heimlich' maneuver on an obstructed pulmonary valve.
- Self-CPR restores blood flow into the lungs.
- CPR reanimates someone suffering from continuous thrombo dextrocardia pulsus interruptus.
Grand Mal Epilepsy, CPR, and Sudden Unexpected Death
Large sticky purple blood clots inside the heart block the outflow of blood at the pulmonary valve. This causes continuous skipped heartbeats and stops blood flow into the lungs and brain, which is sudden thrombocardiac arrest.
Skipped heartbeats cause brain acidosis that triggers unconscious grand mal convulsions. Rhythmic contractions of the arms and legs pump blood into the right ventricle of the heart; and repeating pulsating thrusts of blood perform the Heimlich maneuver on the obstructed valve.
Epileptic convulsions perform unconscious self-CPR (cardiopulmonary resuscitation). This restores blood flow into the lungs and brain, which reanimates an epileptic patient suffering from a sudden thrombocardiac arrest. Failure to expel clots out of the obstructed valve leads to Sudden Unexpected Death in Epilepsy (SUDEP).
Physiology involves complex covariant processes that include respiration, circulation and metabolism. It will melt your brain if you think of everything at once. So take time and focus on one thing until it becomes familiar, and then look at something else. Gradually 'see' the whole picture, which is the Gestalt.
Blood with impurities change the heart rhythm, pulmonary function, and cerebral cognition. Venous clots contain are a mixture of liquid glue, semisolid and solid thrombus. Solid clots in the heart cause skipped beats, while liquid glue (detritus) clogs up pulmonary alveoli, which causes wheezing, panic attacks, and rare anaphylactic suffocation.
Not everyone can go to medical school, but most people can figure out that clots in the heart cause skipped beats that lead to fainting spells.
Take time to 'see' the Gestalt and find joy in your journey as you learn more about blood clots and the protective mechanisms of the heart that prevent sudden death.
