TEST BANK
True/False Questions
1. Sudden cardiac deaths account for about one third of all deaths from cardiovascular diseases.
- SCD is defined as “witnessed cardiac death within one hour of the loss of consciousness due to SCA, or unwitnessed cardiac death within 24 hours of being seen alive and well.”
- Sudden cardiac arrest (SCA) explicitly refers to the abrupt loss of heart function and its ability to pump blood because of interruption of the electrical conduction system of the heart.
- Approximately two-thirds of all sudden cardiac deaths occur “out-of-hospital” or are “dead-on-arrival” at the Emergency Room.
- Approximately 50% of sudden cardiac deaths are unwitnessed.
- Sudden cardiac arrest is synonymous with myocardial infarction.
- Approximately 5-6 million cardiac deaths occur annually in the world population.
- The incidence of SCD in populations of developed nations has increased dramatically in recent years.
- Early administration of cardiopulmonary resuscitation (CPR) and hock therapy (defibrillation) can be life-saving in persons who manifest sudden cardiac arrest.
- Implantable cardioverter defibrillators (ICDs) are not recommended for persons with heart failure to prevent SCD.
