Sequelae is not a word most lay people are familiar with, and even though it is very pertinent to sudden cardiac arrest survivors it’s probably not one they would of heard of before.

Sequelae simply means

“a condition which is the consequence of a previous disease or injury”

And for an SCA survivor this can be from the event or treatment of the event.

These can loosely be grouped into the following:

  • Cardiac
  • Physical/Neurological
  • Psychological



For a sudden cardiac arrest survivor the most obvious repercussion might be damage to the heart, but this would depend largely on the cause of the arrest.

For those who have a heart attack first, blood is prevented from getting to the heart and thus there is a chance that damage will be done.

For those who had a channelopathy or cardiomyopathy as the cause, the temporary cessation of the heart  may not alter the underlying condition greatly, but it may be the first time they become aware of this.

For those diagnosed as idiopathic, and this seems to be an ever growing number within our membership (roughly one third at the end of 2017) the chances are that the heart will not have any obvious deficiencies or defects – but that’s not to say they aren’t there – just currently undetectable.
