17 Possible Causes for Arrhythmias Detected Prenatally, Intracellular Granular Material on Ultrastructural Analysis

  • Northern Epilepsy

    These occur in approximately 50-70% of individuals with TSC, and are most frequently detected prenatally or in the neonatal period.[clinicaladvisor.com] Intracellular accumulation of autofluorescent material results in curvilinear and granular profiles on ultrastructural analysis.[genecards.org] Cardiac and vascular manifestations of TSC include rhabdomyomas, arrhythmias, and arterial aneurysms.[clinicaladvisor.com]

  • Incessant Infant Ventricular Tachycardia

    Supraventricular Tachycardia SVT is the most common serious arrhythmia detected prenatally. It accounts for about 6% of referrals, as shown in Table 2.[glowm.com] They often are detected during routine auscultation at a prenatal visit.[glowm.com] Isolated Extrasystole Isolated extrasystoles are the most commonly noted fetal arrhythmia.[glowm.com]

  • 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

    Familial atrial fibrillation is an autosomal dominant heart condition that causes disruptions in the heart's normal rhythm. This condition is characterized by uncoordinated electrical activity in the heart's upper chambers (the atria), which causes the heartbeat to become fast and irregular. It is associated with[…][en.wikipedia.org]

  • Teratoma of the Brain

    Although cardiac tumors can easily be detected by prenatal US at as early as 20 weeks of gestation, diagnosis requires that they are of sufficient size.[e-ultrasonography.org] Cardiac rhabdomyomas are often multiple, occurring in more than one cardiac chamber and may produce arrhythmias, obstruct blood flow in the heart, or diminish contractility[e-ultrasonography.org]

    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]
