Ventricular fibrillation. Rapid, chaotic electrical signals cause the lower heart chambers to quiver instead of squeezing in a coordinated way. This serious problem can lead to death if a regular heart rhythm isn't restored within minutes. Most people with ventricular fibrillation have an underlying heart disease or had a serious injury. Surgeryto implant a cardioverter defibrillator(ICD), which delivers an electrical pulse to the heart to reset a dangerously irregular heartbeat. Lifestyle changes used to manage heart disease may help prevent heart arrhythmias. Try these heart-healthy tips: Some people with atrial or supraventricular tachycardia may have no symptoms. Others may experience: Ferri FF. Atrial fibrillation. In: Ferri's Clinical Advisor 2023. Elsevier; 2023. https://www.clinicalkey.com. Accessed June 13, 2023.

Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat. The heart rate is 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. Atrial flutter. Atrial flutter is similar to AFib, but the heartbeats are more organized. Atrial flutter also is linked to stroke. 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. In patients with symptomatic Wolff-Parkinson-White Syndrome, medications or ablation may be needed to control paroxysmal supraventricular tachycardia (PSVT). Preventing Atrial or SVTDetermined to show to the world of what he realized was the landscape 4th dimension, Smith spent over two decades piecing together the clues of this unseen grounds to create a remarkably beautiful hand-painted map. 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. Take over-the-counter cough and cold medicines or prescription medications that can cause a SVT episode

But some things can change how electrical signals travel through the heart and cause arrhythmias. They include: 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 TachycardiaIn 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. Panchal AR, et al. 2018 American Heart Association focused update on advanced cardiovascular life support use of antiarrhythmic drugs during and immediately after cardiac arrest. Circulation. 2018; doi:10.1161/CIR.0000000000000613. 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

Obstructive sleep apnea. This condition causes pauses in breathing during sleep. It can lead to a slow heartbeat and irregular heartbeats, including atrial fibrillation. The disruption results in a faster than normal heart rate. 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 (AFib). Chaotic heart signaling causes a rapid, uncoordinated heartbeat. AFib may be temporary and start and stop on its own. But some episodes may not stop unless treated. AFib has been linked to stroke. 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.In a healthy heart, this heart signaling process usually goes smoothly, resulting in a resting heart rate of 60 to 100 beats a minute.
