Reproductive Decision Making and Genetic Predisposition to Sudden Cardiac Death.

Author information

Yeshiva University.



With current genetic technology, it is possible to detect mutations associated with long QT syndrome (LQTS), a hereditary cardiac arrhythmia syndrome. As a result, prospective parents diagnosed with LQTS will have to decide whether or not to prevent its transmission to future generations, either by not procreating or through the use of assisted reproductive technologies or prenatal testing. This paper explores how a hereditary predisposition to sudden cardiac death can influence reproductive decision making.


This study draws from interviews and focus groups with individuals who have personal or family histories of cardiac arrhythmia or sudden death. A keyword search was conducted on interview transcripts to identify quotes for analysis.


Participants expressed complex, often ambivalent attitudes about the prospect of having a child with a predisposition to sudden cardiac death. Their comments reveal conflicting understandings of genetic responsibility and reflect the variable effects of personal experience on reproductive decision making. This paper compares attitudes towards LQTS and other genetic conditions in analyzing the themes that emerged in interviews and focus groups.


The "disability critique" of prenatal testing should be applied carefully to a context of genetic predisposition to sudden cardiac death in order to understand reproductive decision making. Firsthand experience with the condition, among other factors, can weigh heavily in those decisions.
