Atrioventricular reciprocal rhythm and chronic reciprocating tachycardia in a newborn infant with concealed Wolff-Parkinson-White syndrome.

چکیده
A case of atrioventricular reciprocal rhythm and chronic reciprocating tachycardia in a newborn infant is presented. Electrophysiological studies suggest that these rhythm disturbances are related to the presence of a right-sided atrioventricular accessory pathway capable only of retrograde conduction (concealed Wolff-Parkinson-White syndrome). The technique of recording the sequence of atrial activation during the tachycardia is described and its clinical importance emphasised.

Atrial reciprocal rhythm and reciprocating tachycardia in Wolff-Parkinson-White syndrome.
In an infant with type A Wolff-Parkinson-White syndrome, atrial reciprocal beats and attacks of reciprocating tachycardia were repeatedly recorded. Their dependence on a prolongation of the P-R interval could be well demonstrated during Wenckebach periods. Because of the normal aspect of the QRS complex during arrhythmia, the short ventriculo-atrial conduction time (0.08 sec), and the vectorial...
متن کاملLong-term control of reciprocating paroxysmal tachycardia by ventricular pacing in a case of Wolff-Parkinson-White syndrome.
A patient is described with a complex electrocardiographic pattern, including preexcitation, grade 1 atrioventricular block, reciprocal rhythm of atrial origin, and frequent attacks of reciprocating tachycardia at a rate of about 135 beats per minute. Long-term control of these attacks was obtained by synchronous ventricular pacing at 80 beats a minute, which was below the rate during the attac...

Reciprocating tachycardia in a patient with a leftsided atrioventricular accessory pathway (AP) (Kent bundle, type A) capable only of ventriculo-atrial (V-A) transmission is described. The V-A AP is established as an essential link of the tachycardia circuit, as evidenced by : 1) retrograde atrial activation of the left atrium (LA) 60 msec or more before the low and high right atrium during rec...

متن کاملEctopic left atrial rhythm that produces QRS changes in absence of Wolff-Parkinson-White syndrome.
In an 18-year-old patient without manifest or concealed Wolff-Parkinson-White syndrome, spontaneous and paced left atrial impulses penetrated a left-sided AV nodal input and thereafter activated the ventricles in a normal fashion exclusively through the His-Purkinje system. On the other hand, sinus and paced right atrial impulses entered a right-sided atrioventricular nodal input that was compl...
