Coexistence of supraventricular tachycardia and ventricular tachycardia is
rare. A patient with no structural heart disease and wide QRS complex tachy
cardia with a right bundle block configuration and right-axis deviation und
erwent electrophysiological examination. A concealed left atrioventricular
pathway (AP) was found, and atrioventricular reciprocating tachycardia (AVR
T) and left ventricular tachycardia (VT) originating in or close to the ant
erior fascicle of the left ventricle were both induced. Radiofrequency (RF)
catheter ablation of the concealed left AP was successfully performed. Ten
months later, VT recurred and was successfully ablated using a local Purki
nje potential as a guide. Coexistent AVRT and idiopathic VT originating fro
m within or near the left anterior fascicle were successfully ablated.
