Supraventricular tachycardia:

True / False

In infancy it may be associated with maternal systemic lupus erythematosus Incorrect answer selected

May be associated with structural cardiac defects Incorrect answer selected

May respond to Digoxin Correct

Episodes are often difficult to document on a 12-lead ECG Correct

Can cause feeding problems in infants Correct

Explanation

Feeding difficulty in infants is a common manifestation of cardiac insufficiency.

Tachydysrhythmias are rarely difficult to document on a 12 lead ECG but if this should occur then a 24 hour ECG tape recording may be appropriate.

Transplacental passage of anti Ro SSA and anti La SSB antibodies in maternal systemic lupus erythematosus (SLE) can result in neonatal lupus syndrome and associated cardiac rhythm disturbances, most commonly complete heart block.

SVT though is most commonly associated with a structurally normal heart with an accessory pathway, but may also be a feature of congenital heart disease.

Digoxin may be administered in all forms of supraventricular tachycardia (SVT) in which the AV node is involved, except in those with a pre-excitation syndrome that are greater than 1-year-old.
