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

Sinus tachycardia is an increase in the heart rate. In this condition, the heart’s natural pacemaker, the sinus node, sends out electrical signals faster than usual. Cronin EM, et al. 2019 HRS/EHRA/APHRS/LAHRS expert consensus statement on catheter ablation of ventricular arrhythmias. Heart Rhythm. 2020; doi:10.1016/j.hrthm.2019.03.002. Premature heartbeats are extra beats that occur one at a time, sometimes in patterns that alternate with a regular heartbeat. If the extra beats come from the top chamber of the heart, they are called premature atrial contractions (PACs). If they come from the bottom chamber, they are called premature ventricular contractions (PVCs). 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 patients with symptomatic Wolff-Parkinson-White Syndrome, medications or ablation may be needed to control paroxysmal supraventricular tachycardia (PSVT). Preventing Atrial or SVTTachycardia 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. Some people with atrial or supraventricular tachycardia may have no symptoms. Others may experience: 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.

This rapid heartbeat keeps the heart’s chambers from filling completely between contractions, which compromises blood flow to the rest of the body. 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. The heart's electrical system controls the heartbeat. The heart's electrical signals start in a group of cells at the top of the heart called the sinus node. They pass through a pathway between the upper and lower heart chambers called the atrioventricular (AV) node. The movement of the signals causes the heart to squeeze and pump blood.In a typical heartbeat, a tiny cluster of cells at the sinus node sends out electrical signals, called impulses. The signals go through the upper heart chambers to the atrioventricular (AV) node. Next, the signals pass into the lower heart chambers, called the ventricles. This causes the heart to squeeze, which pumps blood throughout the body. Take over-the-counter cough and cold medicines or prescription medications that can cause a SVT episode Heart arrhythmia treatment may include medicines, devices such as pacemakers, or a procedure or surgery. The goals of treatment are to control or get rid of fast, slow or otherwise irregular heartbeats. A heart-healthy lifestyle can help prevent heart damage that can trigger some heart arrhythmias. Types 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.

Complications depend on the type of heart arrhythmia. Possible complications of heart arrhythmias include: Supraventricular tachycardia. This broad term includes irregular heartbeats that start above the lower heart chambers, called the ventricles. Supraventricular tachycardia causes episodes of a pounding heartbeat that start and stop suddenly. Preventing atrial or SVT can be more difficult than treatment. But making the following lifestyle changes may help:

Your doctor should consider and treat the cause of your sinus tachycardia, rather than just treating the condition. Simply slowing the heart rate could cause more harm if your rapid heartbeat is a symptom of a more serious or long-term problem. Ventricular Tachycardia

If you have a slow heart rate and your heart isn't pumping enough blood, you may have a type of bradycardia.

Even though lexicographers have developed more modern ways of updating the dictionary, the people who lived in the 19th and 20th centuries heavily relied on the primitive techniques at their disposal. One of the most committed and brilliant volunteers were Dr. William Minor, a man who provides thousands of entries and was considered at that time a lunatic. For decades he spent his days in an asylum, contributing to the dictionary, one task that distracted him from the grandiose and scary delusions. Episodes of atrial or SVT often can be stopped by one of a few techniques. These actions should be supervised or conducted by a health care professional. They include:
