When the heart suddenly stops beating

Without warning, a man drops to the floor—unconscious.

For most people, this is a universal distress signal that calls for an emergent intervention. While loss of consciousness may also be indicative of other conditions, there is a great likelihood that the person has just experienced sudden cardiac arrest.

defines sudden cardiac arrest as “the sudden, unexpected loss of heart function, breathing, and consciousness.” This is usually a result of an electrical malfunction in the sinoatrial node—the heart’s primary natural pacemaker—which causes an irregularity in the heart rate (also known as arrhythmia). Since the heart’s natural beating rhythm is disrupted, the heart cannot effectively pump blood to the brain, lungs, and other vital organs. Due to this insufficiency, the person would precipitously black out, and death ensues within minutes if proper intervention is not immediately instigated.

The classical primary intervention is Cardiopulmonary Resuscitation (CPR) which can double or triple the chances of a victim’s survival through manual pumping and rescue breathing simulating natural heartbeat and respiration. This, alone, however, does not guarantee successful treatment. Automated External Defibrillators (AEDs) are now used to tweak the fatal arrhythmias and reestablish an effective cardiac rhythm.

According to data from the American Heart Association, “nearly 400,000 out-of-hospital cardiac arrests occur annually in the United States,” making it one of the leading causes of death. With prompt and proper intervention and a portable AED at hand, thousands of lives may be spared from the fatal repercussions of sudden cardiac arrest.

Jason Nikouyeh’s Duramedix Healthcare is offering a high-quality portable AED system that may come in handy to those at risk for sudden cardiac arrest. For more information on the AED system, visit this website.
