WHAT IS SUDDEN CARDIAC DEATH?


Arrhythmia SCD typically refers to a sudden loss of effective contraction of the heart muscle and implies a life-threatening arrhythmia. Usually this is VT or VF. It occurs primarily in patients with a damaged heart (cardiomyopathy, postMI) where there is scar tissue that alters normal electrical conduction. It can also occur in patients w nl hearts (Brugada syndrome, ARVD, long QT) which are rare.
