Cardiac Dysrhythmia
That fleeting feeling in your chest; your heart skipping a beat, or even being breath taken; it could all be signs of being in love, or, in the medical field, it could be the signs of cardiac dysrhythmia (or arrhythmia). The human heart is like the electrical hub of the body. When any electrical hub is disturbed, a slight bump may cause the lights to flicker, or in the worst case, cause the lights to go out; permanently. The same can be said of the human heart. Irregularities in your heart, whether it is one that beats too fast (tachycardia) or one that beats too slow (bradycardia); may not all be life threatening conditions, but some can lead to cardiac arrest
A normal heartbeats at a rate of 60-100 beats per minute. Cardiac dysrhythmia occurs when there is a disturbance in the normal rhythm of the heart. Atrial fibrillation and atrial flutter are two of the most common types of cardiac dysrhythmia. “These atrial arrhythmias may interfere with the heart’s ability to pump blood properly from its upper chambers (atria). The atria may not always empty completely, and blood remaining there too long may stagnate and potentially clot. Such clots may travel to other parts of the body, where they may cause blockages in the blood supply to the limbs, brain or heart. ("Cardiac Arrhythmias." Cardiac Arrhythmias. N.p., n.d. Web. 11 Dec. 2013, retrieved from http://www.hopkinsmedicine.org/) The American Heart Association reports that 383,000 emergency out-of-hospital treated cardiac arrests occur in the United States. A number of factors can cause cardiac dysrhythmia; smoking, heavy alcohol use, drugs (ie; cocaine or amphetamines), some prescription or over-the-counter medicines, or even too much caffeine or nicotine.

...atch all” for a ton of different ailments that leads to cardiac dysrhythmia. I honestly had no clue that there were so many “levels” to this disease and am happy I got to educate myself further. Heart problems and high blood pressure is such a huge issue in my family and when you know more, you do more to help prevent this issue from becoming something more serious than it needs to be. The resources weren’t as hard to find once I understood that there were different names and types of heart issues that fell under this one subject.

There are several different heart problems that show up as an abnormal EKG reading. For example, a heart block can occur when there is a delay in the signals coming from the SA node, AV node, or the Purkinje fibers. However, clinically the term heart block is used to refer to an AV block. This delays or completely stops communication between the atria and the ventricles. AV block is shown on the EKG as a delayed or prolonged PR interval. The P wave represents the activity in the atria, and the QRS complex represents ventricular activity. This is why the PR interval shows the signal delay from the AV node. There are three degrees of severity, and if the delay is greater than .2 seconds it is classified as first degree. Second degree is classified by several regularly spaced P waves before each QRS complex. Third degree can be shown by P waves that have no spacing relationship to the QRS complex. Another type of blockage is bundle branch block. This is caused by a blockage in the bundle of His, creating a delay in the electrical signals traveling down the bundle branches to reach the ventricles. This results in a slowed heart beat, or brachycardia. On an EKG reading this is shown as a prolonged QRS complex. A normal QRS is about .8-.12 seconds, and anything longer is considered bundle branch block. Another type of abnormal EKG reading is atrial fibrillation, when the atria contracts very quickly. On the EKG this is shown by no clear P waves, only many small fibrillating waves, and no PR interval to measure. This results in a rapid and irregular heartbeat. On the other hand, ventricular fibrillation is much more serious and can cause sudden death if not treated by electrical defibrillation.
In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays

Atrial fibrillation (AF) is a cardiac arrhythmia. It is the most common arrhythmia and it has implications for patients and anaesthetists alike. The anaesthetist must take into consideration the physiological and pharmacological implications of this common arrhythmia.
Cardiac dysrhythmias come in different degrees of severity. There are heart conditions that you are able to live with and manage on a daily basis, and those that require immediate attention. Atrial fibrillation is one of the more frequently seen types of dysrhythmias (NIH, 2011). The best way to diagnose a heart condition is by reading a cardiac strip (Ignatavicius &Workman, 2013). Cardiac strips play a major role in the nursing world, allowing the nurse and other trained medical professionals to interpret what the heart is doing.
Wyeth-Ayerst also focused its research on cardiovascular therapies and mental health products. Its cardiovascular research concentrates on medication for diseases such as arrhythmia and hypertension. Their anti-arrhythmia franchise leads the U.S. market, reflecting Wyeth-Ayerst’s and AHP’s recognition of life-threatening ventricular arrhythmia (Tardiff 114).
State: The cardiac cycle is composed of five stages which each trigger the relaxation or contraction of the atria or ventricles and direction of blood flow.
Although HCM is the most common cause of sudden death in the general public, it is not well known. This is partially because in the U.S., we do not have enough doctors to evaluate results from an ECG, which
Other than atrial fibrillation and atrial flutter, this is the most common supraventricular tachycardia seen in practice.11 A large minority of adults (up to 40% in some cohorts) are born with 2 pathways that can conduct electricity in the AV node, rather than 1. Under the right conditions, AV node reentrant tachycardia (AVNRT) can be initiated by a premature atrial or ventricular beat. If the 2 pathways are able to sustain a stable circuit, the atrium and the ventricle are depolarized almost simultaneously. As a result, on the ECG, the P wave is not seen, is buried in the QRS complex, or is seen at the terminal portion of the QRS, typically as a pseudo-s (negative) wave in the inferior leads or a pseudo-r0 in lead V1. Because this tachyarrhythmia depends on the AV node, both vagal maneuvers and adenosine are potential acute treatment options. In the outpatient setting, if the patient is in a sustained supraventricular tachycardia, attempting vagal maneuvers
One of the leading causes of death in the United States is heart disease. “Approximately every 29 seconds one American will have a heart attack, and once a minute one American will die from a heart attack” (Ford-Martin and Odle, 915). According to the Gale Encyclopedia of Alternative Medicine men over the age of 45 and women over the age of 55 are considered at risk for heart disease. Heart disease is a major cause of death. It is beneficial to individuals who seek to prevent heart disease to recognize the risks leading to heart attacks as they are one of the primary indications of developing heart disease; especially those that fall into the at risk age groups. These risks consist of some that cannot be changed such as heredity risks, or those that can change such as smoking habits. It is very important to know these specific risks for prevention and to understand the symptoms of heart attacks, such as sweating or the feeling of weakness so if these or other symptoms occur people are aware. Finally heart disease treatment is of vital importance if you experience a heart attack so you can learn how to prevent another one from occurring.
Arrhythmia I am doing my report on Arrhythmia. It affects the cardiac muscle, the heart. Arrhythmia causes three types of problems. It causes the heart to pump too slowly (bradycardia), it causes the heart to pump too fast (tachycardis), and it causes the heart to skip beats (palipations).
Atrial fibrillation, also known as afib, can cause the heart to beat up to 400 beats per minute (Cohen 32). Afib occurs whenever

The most serious cardiovascular epidemic that affect about more than three million people in US (Chapa, Thomas, Friesmann, & Akintade 2015) is Atrial fibrillation (AF). Few risk factors which enhance the prevalence rate of AF are, diabetes, male gender,
dizziness, and butterflies in the stomach. These physiological reactions are completely normal when falling in love. The second type of feeling that one endures when falling in love is attachment. Attachment is a bond or a special tie between people that are attracted to one another. Attachment helps keep people together and has more to do with feelings of security than excitement.
