Cardiac Arrest Warning Signs
The dramatic and rapid halt of heart function in sudden cardiac arrest may be preceded by chest pain and other symptoms.
Based on its name alone, sudden cardiac arrest (SCA) seems like a condition that strikes unexpectedly. And indeed, the sudden stoppage of heart function, which usually ends in death, is not necessarily an event that is easily predicted by tests or a physical exam. But a recent study suggests that an SCA may not be as much of a surprise as previously thought. Research indicates that about half of SCA victims experience symptoms within a month prior to their events. Symptoms included chest pain, shortness of breath, heart palpitations and more vague feelings, like nausea and back pain.
