The R-on-T phenomenon was first described by Smirk in 1949 as R waves interrupting T waves12 In 1966 Francois Dessertenne described a specific electrocardiographic form of polymorphic ventricular tachycardia PVT characterized by changing amplitude of the complexes with a characteristic twist around the isoelectric baseline with prolonged QT interval which he termed. Relation to the genesis of ventricular tachycardia.

2002 by The McGraw-Hill Companies Inc. Case 1 had a typical Lown-Ganong-Levine syndrome in which the shortening of the P-R interval was due to a reduction of the A-H interval. More recent experimental and clinical observations suggest that R-on-T is not a critical determinant of primary ventricular fibrillation in acute.

Should you worry about having pvcs that occasionally occur on a preceding t wave r-on-t.

Early observations suggested that R-on-T was likely to initiate sustained ventricular tachyarrhythmias. Case 1 had a typical Lown Ganong Levine syndrome in which the shortening of the P-R interval was due to a reduction of the A-H interval. Ventricular fibrillation in an 83-year-old man after coronary angiography was caused by the R-on-T phenomenon due to a sensing failure on the part of a temporary pacemaker with ventricular.

20 percent were initiated by a premature complex on the T wave R on T R-RQ-T less than 1 and 93 44 percent had initiating premature complexes that occurred directly after onset of the sinus P wave R on P.
