Practice EKG: R-on-T-VT

-



Explanation:  R-on-T ventricular tachycardia.  The underlying rhythm is sinus bradycardia.  The P waves are upright and uniform and are associated with a QRS complex.  The PR interval is prolonged.  The QRS complexes are narrow.  The first beat of the VT lands on the later part of the T wave. Stimulation of the ventricle at this time precipitates the run of ventricular tachycardia.  The first half of the run the heart rate is around 125 bpm but as it progresses, the rate increases to about 150 bpm.
