The time it takes for help and treatment to occur is a life and death situation during SCA. Ninety-five percent of those who experience SCA die because they do not receive life-saving defibrillation within four to six minutes, before brain and permanent death begin to occur.

The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals prompt the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. The process begins in the upper chambers of the heart (atria), which pump blood into the lower chambers (ventricles).
Sudden Cardiac Arrest (SCA) occurs abruptly and without warning, and two-thirds of SCA deaths occur without any prior indications of heart disease. In fact, SCA can happen to people of all ages and health conditions.
The most common cause of SCA is a dangerous and abnormal heart rhythm called ventricular fibrillation (VF). In VF, the electrical signals that control the lower chambers of the heart (ventricles) become chaotic. This sends the ventricles into fibrillation, an extremely rapid and irregular quivering that cannot effectively pump blood to the body.
Atrial flutter (AFL) is a common abnormal heart rhythm, similar to atrial fibrillation, the most common abnormal heart rhythm. Both conditions are types of supraventricular (above the ventricles) tachycardia (rapid heart beat). In AFL, the upper chambers (atria) of the heart beat too fast, which results in atrial muscle contractions that are faster than and out of sync with the lower chambers (ventricles).
HRS is hosting a Twitter Chat on Tuesday, November 28 from 4-5 p.m. ET
This course is designed to provide the learner with the most up to date evidence for ICD and CRT based therapy. It provides a state-of-the-art review of ICD and CRT management as well as an in-depth review of implantation techniques, programming, complications and follow-up aspects.
EP Live is a 2-day intensive educational meeting targeting practicing electrophysiologists as well as fellows in training. The meeting consists of four sections: AF ablation, VT ablation, devices and new technologies. In addition, a panel of recognized experts will provide commentary and discussion. Previously recorded cases will also be shown.
By far, the Global CardioVascular Clinical Trialists Forum (CVCT), now in its 14th year, provides the best annual update and in-depth understanding of the trials shaping the evidence base of modern cardiology.
Join academics, trialists, regulators, R&D experts and young investigators for an interactive exchange covering all areas of CV trials. CVCT Forum is the only event focusing specifically on clinical trials in cardiovascular disease that brings together key decision makers, conceivers of clinical trial protocols, investigators, regulatory authorities, clinical research associations, cardiologists, general practitioners, epidemiologists and industry.
Complimentary Affiliate membership is available to individuals who are enrolled in an approved electrophysiology or cardiology training program.
