Paced Rhythms
Refers to pacemakers response to sensed native cardiac activity. T = Sensed activity Appropriate discordance in a ventricular paced rhythm.
This rhythm is easily identified by the conspicuous presence of a pacing spike immediately preceding the P waves and the QRS complexes. The PR interval is measured from the atrial spike to the ventricular spike. This “delay” is programmed by the physician during implantation to.
Pacemaker Rhythm Sample Tracing. pacemaker rhythm EKG tracing Failure to capture means that the ventricles fail to response to the pacemaker impulse.
Description:Ventricular pacing spikes precede each QRS complex except perhaps complex 2 — although the QRS morphology in this complex is identical to the rest of the ECG, suggesting that this beat is also paced No atrial pacing spikes are seen. Analyze the strip for failure to capture, failure to sense, oversensing or failure to pace. Are P waves present? The LBBB morphology is consistent with a ventricular pacing electrode located in the right ventricle. The varying relationship between the atrial and ventricular pacing spikes is best understood by examining the lead II rhythm strip below: Measure the paced interval:
