7 Possible Causes for Arrhythmias Detected Prenatally

  • Tachyarrhythmia

    Overall, these serious tachyarrhythmias comprise less than 10% of arrhythmias detected prenatally.[clinicaladvisor.com] The most common tachyarrhythmia is supraventricular tachycardia (SVT), representing up to 5% of all fetal arrhythmias.[clinicaladvisor.com]

  • Familial Atrial Fibrillation

    J Electrocardiol. 2014 Mar-Apr;47(2):158-65. doi: 10.1016/j.jelectrocard.2013.12.004. Epub 2013 Dec 10.

  • Long QT Syndrome 13

    Hsiao et al. [ 30 ] analyzed the outcomes of 123 fetuses with prenatally detected cardiac malformations and/or cardiac arrhythmias.[karger.com] Hsiao SM, Wu MH, Jou HJ, Lee CN, Shyu MK, Shih JC, Hsieh FJ: Outcome for fetuses with prenatally detected congenital heart disease and cardiac arrhythmias in Taiwan.[karger.com] Hahurij et al. [ 31 ] analyzed the causes and outcomes of 44 fetuses with prenatally detected tachy- and bradyarrhythmias after excluding sinus tachycardia, transient sinus[karger.com]

  • Familial Cutaneous Collagenoma

    These occur in approximately 50-70% of individuals with TSC, and are most frequently detected prenatally or in the neonatal period.[clinicaladvisor.com] Cardiac and vascular manifestations of TSC include rhabdomyomas, arrhythmias, and arterial aneurysms.[clinicaladvisor.com] While the tumors themselves are benign, they may cause inflow or outflow obstruction, cardiac arrhythmias, or impair ventricular function and lead to congestive heart failure[clinicaladvisor.com]

  • Levocardia

    Postnatally, intestinal malrotation with no evidence of intestinal obstruction or asplenia was detected. Neither of the cases had reported cardiac arrhythmias.[ncbi.nlm.nih.gov] Interestingly, many living infants with heterotaxy syndrome exhibited arrhythmia, many more than were detected prenatally [33/49 (67.3%) vs. 21/103 (20.3%), P Our study demonstrated[bmcpregnancychildbirth.biomedcentral.com] The child in the second case was found to have an interrupted IVC with azygos continuation prenatally.[ncbi.nlm.nih.gov]

  • Asplenia Syndrome

    Electrocardiogram (ECG): This is useful in the detection of arrhythmias and other abnormalities in cardiac function Echocardiogram: This is a non-invasive imaging technique[symptoma.com] Prenatal ultrasound: It is possible to diagnose AS before birth, as ultrasound can be used to identify cardiac abnormalities and asplenia.[symptoma.com]

  • Progressive Epilepsy-Intellectual Disability Syndrome, Type Finnish

    These occur in approximately 50-70% of individuals with TSC, and are most frequently detected prenatally or in the neonatal period.[clinicaladvisor.com] Cardiac and vascular manifestations of TSC include rhabdomyomas, arrhythmias, and arterial aneurysms.[clinicaladvisor.com] While the tumors themselves are benign, they may cause inflow or outflow obstruction, cardiac arrhythmias, or impair ventricular function and lead to congestive heart failure[clinicaladvisor.com]
