Body Temperature Change May Trigger Sudden Cardiac Death

Scientists, including SFU professor Peter Ruben, have found that sudden death caused by cardiac arrhythmia can be triggered by changes in body temperature. The study is published in the Journal of Physiology.

The soccer player who drops dead in the middle of a game, or the infant who dies during sleep is often a victim of arrhythmia. Sudden cardiac death has several causes, including inheritable mutations in our DNA affecting structure and function of proteins in the heart. Simon Fraser University professor Peter Ruben found when studying the proteins that underlie electrical signaling in the heart, and subjecting those proteins to conditions that are similar to the stress of exercise, in some cases, temperature can cause changes that trigger arrhythmia.

Mission & Vision

The mission of the Sudden Cardiac Arrest (SCA) Foundation is to prevent death and disability from sudden cardiac arrest. The vision of the SCA Foundation is to increase awareness about sudden cardiac arrest and influence attitudinal and behavioral changes that will reduce mortality and morbidity from SCA.
