Sudden Cardiac Death: Why Does It Happen?

A sudden cardiac arrest is caused by the irregular obstruction of the heart function accompanied by breathing problems and loss of consciousness. The cardiac arrest symptoms are accompanied by heavy sweating and severe pain in the chest region.

If the cardiac arrest symptoms are not addressed at the right time in an emergent method; it may lead to a sudden cardiac death. Most of the cardiac arrests in India lead to death as the cardiac arrest symptoms are not understood by the person to whom it is happening. Most of the cardiac arrest symptoms are not sudden. They happen because of latent symptoms which have existed and been untreated for a long time.

Not many of the people might heed to the mild cardiac arrest symptoms, leading to sudden cardiac death.  

A Cardiac Arrest might not lead to death if they get it treated at the earliest stage. With immediate medical action or on administering cardiopulmonary resuscitation (CPR) a person's life can be saved purely based on the observation of the cardiac arrest symptoms.

The disease is caused by clogged arteries, where there are deposits of Cholesterol. This makes the heart susceptible to a cardiac arrest.
