A Particular Bigeminy During Atrial Tachycardia
The ECG shows clearly visible P waves only in lead V1 (Fig. 1). Regular PP intervals and an isoelectric baseline are present between the P waves, so the diagnosis is atrial tachycardia [1]. During the ECG recording, lead V1 shows 12 P waves but some of these are not visible because they are concealed by the QRS complex (Fig. 2). In lead V1, the beats following the long RR intervals are conducte...
متن کاملRegular supraventricular tachycardia with irregular atrial activations.
A 19-year-old woman developed a recurrent supraventricular tachycardia (SVT) 3 months after catheter ablation of a typical slow-fast type atrioventricular nodal re-entrant tachycardia (AVNRT). During the procedure, the slow pathway was mapped and ablated anterior to the bottom of the coronary sinus (CS) ostium. She was referred to our institute and underwent electrophysiological testing a year ...
متن کاملRecurrent Supraventricular Tachycardia with a Different Retrograde Atrial Activation Sequence: What is the Mechanism?
UNLABELLED A young man underwent 2 catheter ablation procedures because of frequent episodes of paroxysmal supraventricular tachycardia (SVT). A left accessory pathway was ablated in the first procedure. The patient underwent the second ablation procedure due to a recurrent SVT demonstrated by 12-lead electrocardiogram two weeks after the first procedure. During the second procedure, a SVT with...
متن کاملSupraventricular tachycardia in patients with right atrial isomerism.
OBJECTIVES To clarify the prevalence and mechanism of supraventricular tachycardia in patients with right atrial isomerism. BACKGROUND Paired SA and dual atrioventricular (AV) nodes have been described in patients with right atrial isomerism. However, the clinical significance remains unclear. METHODS From 1987 to 1996, a total of 101 patients (61 male, 40 female) and four fetuses were iden...
متن کاملMultiple atrial thrombi in a neonate presenting with supraventricular tachycardia
Case report A 21-day-old female term neonate presented to a regional hospital in New Zealand with a 2-day history of poor feeding and jaundice. Antenatal period was unremarkable, including no history of fetal tachycardia. At presentation, tachycardia was noted and a 12-lead electrocardiogram confirmed SVT at a rate of 240 beats per minute (Figure 1). Cold water immersions and adenosine boluses ...
