Postural Orthostatic Tachycardia Syndrome (POTS)
From the time we are born till the time we die there is a muscle inside of us that is the root of our existence, it’s a muscle so dominant that we can actually hear and feel it throughout our growth, daily activities, and emotions of our everyday life.
Inside our body there is a powerful muscular pump, which is known as the one of the main organs in the human body. This hollow, cone shaped, pump lies slightly left within the center of the chest called our heart. The heart is made up of different structures and actions in order for it to work, combined with a network of blood vessels form what we know as the cardiovascular system.
The heart size varies with body size pumping blood to

Likewise, Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle, forming the complete circulation.
All in all the heart is a vital organ we need to survive. And with each vessel and each valve working together give us the lubb-dupp sound we are all so familiar with making each heartbeat worth wile. But, what if the heart beat we are all familiar with suddenly had a change of pace from something that may seem small to us, but a big deal to others.
Standing up is something that we have been doing since we were kids it is something that most of us would take for granted. Since, our bodies automatically adjust to the pull of gravity by increasing vascular tone, heart rate and cardiac output, blood vessels contract, heart rates increase and our systolic blood pressure which is the blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart, remains the same or decreases slightly while diastolic pressure which is the minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood increases slightly (Brunner & Suddarth, 2000, p. 546). Our bodies operate in perfect homeostasis and we stand up with little effort. Yet, the
Once deoxygenated blood enters the right atrium, it travels through the tricuspid valve into the right ventricle. Then the blood goes through the pulmonary semilunar valve into the pulmonary arteries. Once in the pulmonary arteries the blood is pumped into the lungs where it is then oxygenated. The blood goes from the lungs through the pulmonary vein into the left atrium. From there it passes through the bicuspid valve into the left ventricle where it is then pumped out through the aortic semilunar valve into the aorta (Drake 101). From the aorta the blood goes to the right and left coronary arteries.
First the de-originated blood goes into the right atrium. And the originated blood goes through the left atrium. The right atrium then pumps blood through the tricuspid valve into the right ventricle, and the left atrium pumps blood through the bicuspid valve into the left ventricle. The right ventricle contracts, semi lunar valve opens and deoxygenated blood travels back to the lungs. The left ventricle contracts, semi lunar valve opens and oxygenated blood goes out to the body.
In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left
Blood then travels out toward the lungs for oxygenation via the pulmonary artery and returns to the heart through the pulmonary veins entering the left atrium. It is pumped through the mitral valve into the left ventricle to exit the aortic valve to the circulation via the aorta. The questions asked in the lab packet directly related to the anatomy and physiology of the heart which allowed to understand how the heart works as a
First, there is a lot of information about the heart. The organ works ceaselessly, beating 100,000 times a day, 40 million times a year—in total clocking up three billion heartbeats over an average lifetime. It keeps the body freshly supplied with oxygen and nutrients, while clearing away harmful waste matter. The fetal heart evolves through several different stages inside the womb, first
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns
The heart is a muscular pump about the size of a fist. This muscle is continuously pumping blood to the circulatory system at a rate on average of 100,000 times a day. Arrhythmia’s can cause an abnormal rhythm to this rate because of a change in the heart’s electrical system. These arrhythmias can either cause the heart to beat too slowly, bradycardia, or tachycardia, where the heart beats too fast. Supraventricular Tachycardia (SVT) is one specific form of tachycardia. When a person develops SVT it causes the heart tissue to develop activity similar to a pacemaker in the upper chambers, or the region above the ventricles (AHA, 2015). This produces an abnormally fast heartbeat. Understanding this condition is
During pulmonary circulation the blood moves from the heart to the lung to become oxygenated, the blood is then circulated back to heart. Deoxygenated blood enters the right atrium from the superior and inferior venae cavae. The blood is pumped through the tricuspid valve into the right ventricle. The blood is then pumped through the pulmonary valve and into the pulmonary artery from the right ventricle.
Postural Orthostatic Tachycardia Syndrome is a condition that is rarely recognized by medical professionals. At the moment, no cure has been found for this condition only medication to control the symptoms. Postural Orthostatic Tachycardia Syndrome is an autonomic dysfunction that presents with symptoms of orthostatic intolerance, such as fatigue, dizziness, headaches, nausea, palpitations, presyncope and syncope, which are generally relieved by lying down (Busmer 16).Postural Orthostatic Tachycardia Syndrome has remarkable effect on a person’s life, the symptoms or limitations of daily activity can vary from something mild to something severe. This condition can have a widespread effect of the body systems. For instance Postural Orthostatic
Many people have written songs and poems and television scripts about heartbreak, but very few know the science behind it. A simple internet search conducted by the heartbroken individual would tell them that what they’re feeling is not unique to them, but rather that they are part of a group of people suffering from an illness called cardiomyopathy. Quite a few people who fall under this category were placed there at the hands of an ex-lover. However, Willow Chance finds herself there at the hands of an inattentive driver who took away the lives of her adoptive parents in the blink of an eye.
The right atrium is where the process begins. Then, blood travels through the tricuspid valve to the right ventricle, and from there to the pulmonary artery. Once the blood travels through the pulmonary artery, it reaches the lungs. While in the lungs, the blood goes through a gas exchange: deoxygenated blood gets oxygenated (The gas exchange takes place in the alveoli, which are tiny air sacs in the bottom of the lungs
Today millions of Americans live or have lived with Atrial fibrillation. The main concern with this health issue is that many people who lived with it sometimes are not aware of it. Atrial fibrillation is defined by Mayo Clinic (2012) as “an irregular and often rapid heart rate that commonly causes poor blood flow to the body”. It occurs when the four chambers of the heart have a disrupted rhythm. The abnormal functionality of health may lead to a stroke because of the possible blood clot that will be formed. The Atrial fibrillation or Afib put the body in a situation without oxygen and nutrients because the body is not well supplied by a heart that is became weak. In general, only few people will feel change in their heartbeat. They may verbalize
The heart is one of the most important organs in an organism’s body, no matter if they are aquatic, amphibian, or a mammal. This super organ works automatically, able to pump massive amounts of oxygen rich blood through the body by means of electrical impulses and the opening and closing of valves within its many layers. It is what keeps us and every other creature on this earth alive; so it is only natural for one to fear when there might be a problem with one’s heart. A cardiac arrhythmia can happen to anyone, no matter the age, race, or gender, and as such, doctors and scientist have spent years trying to better understand the heart and the way it functions so that they can try to prevent these problems and save millions of lives.
What is POTS? Postural Orthostatic Tachycardia Syndrome (POTS) is a type of dysautonomia1 that affects numerous people around the world. When diagnosing POTS, a Tilt Table test is frequently used and the heart rate of the patient must increase by 30 beats per minute (bpm) or more, or be over 120 bpm, within the first 10 minutes of being placed in the vertical position from the supine position and with an absence of orthostatic hypotension2. Patients affected with POTS may have symptoms that range in severity. Although many POTS patients are able to continue with typical activities, some POTS patients are not able to. For others that are not able to fulfill a normal life, symptoms may be so severe that everyday activities such as bathing, eating, walking, or standing can be difficult or impossible. POTS patients have trouble changing positions because there is decreased blood flow to the brain. When there is decreased blood flow to the brain, it can cause severe dizziness and fainting (Garland). “Many people, who have POTS, experience presyncope. During presyncope episodes, symptoms are similar to a faint but no loss of consciousness is experienced” (Pots-). POTS patients can also have severe pain that is debilitating. Sometimes POTS patients will have other diseases or complications along with POTS that disables them.
As the process occurs with each heart beat, it is easy to see that John’s heart is under continuous strain from the added work. Pinneo/19958 feels that any factor that puts strain on the heart causing it to work hard is one of the causes of heart failure.
