Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat. The heart rate is less than 60 beats a minute.

If an arrhythmia is causing heart failure symptoms, treatment to control the heart rate may help the heart work better. Prevention To understand the cause of heart arrhythmias, it may help to know how the heart works. How does the heart beat? Complications depend on the type of heart arrhythmia. Possible complications of heart arrhythmias include: Thyroid disease. Having an overactive or underactive thyroid gland can raise the risk of irregular heartbeats. Atrial or supraventricular tachycardia (SVT) is a fast heart rate that starts in the upper chambers of the heart. Some forms of this tachycardia are paroxysmal atrial tachycardia (PAT) and paroxysmal supraventricular tachycardia (PSVT).

A type of arrhythmia called ventricular fibrillation can cause a dramatic drop in blood pressure. This can cause the person to fall to the ground within seconds, also called collapse. Soon the person's breathing and pulse will stop. Ventricular fibrillation is an emergency that needs immediate medical help. It's the most frequent cause of sudden cardiac death. Even though Winchester still writes travels books, he has adapted the narrative nonfiction form he adopted for The Professor and the Madam. Winchester is a resident of Berkshire County, Massachusetts. If you or someone you love has AFib, learn more about what it is; why treatment can save lives; and what you can do to reach your goals, lower your risks and live a healthy life. Lee R. Atrial fibrillation: Surgical ablation. https://www.uptodate.com/contents/search. Accessed June 13, 2023. If there's no one nearby trained in cardiopulmonary resuscitation (CPR), provide hands-only CPR. Push hard and fast on the center of the chest. Do 100 to 120 compressions a minute until medical help arrives. You do not need to breathe into the person's mouth.

Caffeine, nicotine or illegal drug use. Stimulants can cause the heart to beat faster and may lead to the development of more-serious arrhythmias. Illegal drugs, such as amphetamines and cocaine, may greatly affect the heart. Some may cause sudden death due to ventricular fibrillation. In a healthy heart, this heart signaling process usually goes smoothly, resulting in a resting heart rate of 60 to 100 beats a minute.

Substances in the blood called electrolytes help trigger and send electrical signals in the heart. Potassium, sodium, calcium and magnesium are examples of electrolytes. If the body's electrolytes are too low or too high, it may interfere with heart signaling and lead to irregular heartbeats.Take over-the-counter cough and cold medicines or prescription medications that can cause a SVT episode Normally, your heart contracts and relaxes to a regular beat. In AFib, the upper chambers of the heart, or the atria, beat irregularly. Because not enough blood is being pumped out of the atria, blood pools in the area. The pooled blood can clot – which can be extremely dangerous. Tachycardia in adults refers to a heart rate of more than 100 beats per minute. How that’s defined may depend on your age and physical condition. Unfortunately for him, instead of getting praises and honors, he was sent to a debtors prison, accused of plagiarism and became homeless for ten years. It was in 1831 that Smith, (now known as the father of the modern geology) was awarded the Geological Society of London’s best award and King William IV assured him of a lifetime pension.

What is arrhythmia? American Heart Association. https://www.heart.org/en/health-topics/arrhythmia. Accessed June 13, 2023. Atrial fibrillation is a quivering or irregular heartbeat, or arrhythmia. Atrial fibrillation, also known as AFib or AF, can lead to blood clots, stroke, heart failureand other heart-related complications. Over 12 million people are projected to have AFib by 2030. While on field assignment, Winchester came across a copy of Coronation Everest by James Morris, a book that gave a detailed account of the 1953 expedition that resulted in the first ever successful ascent of Mount Everest. The book inspired Winchester to become a writer, and so he sought advice from the book author by mail. Morris convinced Winchester to give up geology and get a job as a newspaper writer.

Heart Rhythm. 2020; doi:10.1016/j.hrthm.2019.03.002. Ventricular tachycardia. This rapid, irregular heart rate starts with faulty electrical signals in the lower heart chambers, called the ventricles. The rapid heart rate doesn't let the ventricles properly fill with blood. So the heart may not be able to pump enough blood to the body. Ventricular tachycardia may not cause serious problems in people with otherwise healthy hearts. In those with heart disease, ventricular tachycardia can be an emergency that needs immediate medical care. A premature heartbeat may feel like your heart skipped a beat. These extra beats are generally not a concern. They rarely mean you have a more serious condition. Still, a premature beat can trigger a longer lasting arrhythmia, especially in people with heart disease. Occasionally, having very frequent premature ventricular beats may lead to a weak heart.

But a low resting heart rate doesn't always mean there's a problem. If you're physically fit, your heart may be able to pump enough blood to the body with less than 60 beats a minute.

The author, Simon Winchester gives a detailed description of the painstaking task of what was need to create a full and comprehensive collection of every single word in the English language.

In writing The Professor and the Madman, Simon Winchester has carefully researched and investigated to provide precise and accurate details of what it took to create the OED. The story closely relates to the modern project management problems, for instance, the size of the project, the amount of time required to complete and the number of people needed to finish.
