When discussing heart health, heart attacks and cardiac arrest are two terms that are often mistaken for one another. Understanding the difference between heart attack and cardiac arrest can help in recognizing symptoms, seeking prompt medical care, and even saving lives. What is Cardiac Arrest?

Barr’s death at 39 from sudden cardiac arrest was caused by mitral valve prolapse—a heart valve defect that can affect the heart’s ability to pump blood. It can, in some cases, lead to death. You may not know Carol Barr, but in the future, she could save your life.

Sudden cardiac death is one of the main causes of mortality in patients with known or occult cardiac disease and is potentially preventable by early resuscitation. 1 Underuse of AEDs is a multifaceted problem with the number of available devices in a given distance to a person with out-of-hospital cardiac arrest (OHCA).

Brugada syndrome is thought to account for about one fourth of sudden cardiac deaths in individuals with structurally normal heart. This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. I am always happy to see this ECG of Brugada syndrome as it was sent to me by Prof.

This discussion comes from this previous post: Hyperthermia and ST Elevation Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias. Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7].

Further history later: This patient personally has no further high risk features (syncope / presyncope), but her mother had sudden cardiac arrest in sleep. Conclusion of this paper: Fever is a great risk factor for arrhythmia events in Brugada Syndrome patients. We repeated the ECG: Brugada pattern is mostly resolved.
