 Sudden Cardiac Death

The heart suddenly stops when its electrical rhythms are disrupted, causing the heart’s lower chamber to quiver. Death occurs within minutes.

Prevention :

Patients with damaged hearts are at risk. An implanted defibrillator slashes deaths in patients whose pumping capacity is below a certain threshold.

Drugs called beta blockers reduce the rate of sudden cardiac deaths.

Treatment :

Immediate action is essential.

Cardiopulmonary resuscitation keeps blood flowing, limiting damage.

An electric shock from an automated defibrillator can reset the heart rhythm. Many public venues now have them.

Cooling a patient to 90 to 93 F degrees can slow brain damage.
