چکیده

avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. therefore, we suggest that there was a common pathway among all kinds of these arrhythmias, which were ablated with single rf lesion.

Unusual examples of supraventricular re-entrant tachycardias.

Programmed electrical stimulation of the heart uncovered unusual findings in four patients suffering from supraventricular tachycardias. They included 1) two supraventricular tachycardias of different location and frequency in the same patient, 2) increase in rate of a re-entrant atrioventricular (A-V) nodal tachycardia followed by the development of 2-to-1 A-V block, 3) a "gap" in A-V conducti...

Sustained Supraventricular Tachycardias Following Open Heart Surgery

A technique is described to control recurrent or sustained supraventricular tachycardia associated with rapid ventricular rates following open heart surgery. The technique utilizes a pair of temporarily implanted atrial epicardial wire electrodes to pace the heart. In one group of patients with recurrent atrial flutter and 2:1 A-V conduction, continuous rapid atrial pacing at 450 beats/min prod...

Supraventricular tachycardias in the emergency room.

Supraventricular tachycardia (SVT) is the most common tachyarrhythmia in children. There are a few studies on the epidemiology, clinical characteristic and treatment of this condition in Asian children presented at the Emergency Room (ER). This study aims to determine the epidemiology, clinical characteristics, medications use for SVT and responses in children in the ER. Data were collected via...

Propranolol in supraventricular tachycardias of childhood. 9 children with supraventricular tachycardias refractory to conventional therapy were treated with propranolol. In 3 children normal sinus rhythm was restored. In 3 others frequency of paroxysmal arrhythmias was decreased. In 1 reduction of ...

Paroxysmal Supraventricular Tachycardias and the Preexcitation Syndromes

Paroxysmal supraventricular tachycardia (PSVT) has been a well-recognized clinical syndrome and an electrocardiographically defined arrhythmia since the early days of electrocardiography. The clinical syndrome was defined in European literature in the 19th century. In 1867, Cotton reported on an “unusually rapid action of the heart,” and this was followed by further observations by French and G...

Diagnosis and management of supraventricular tachycardias.

Supraventricular tachycardias (SVTs) are rhythm disturbances arising within the sinus node, the atrial tissue or the atrioventricular node. They are characterized by narrow QRS complex morphology on an electrocardiogram (ECG) and rapid heart rate. A correct diagnosis is essential for treatment and can sometimes be challenging as different rhythm disturbances may have a similar appearance on the...
