EKG Rhythm Strips 23: Paced Rhythms

Identify the following rhythms: 1. 2. 3.   4.   5. Answers 1. Ventricular Demand Pacing.   The patient has an underlying atrial flutter. 2. Ventricular Demand Pacing Ventricular Demand Pacing.  The underlying rhythm looks like atrial flutter.  The pacer spikes are small and difficult to see on complexes 3, 4, 5, and 7.  My first thought about this rhythm was that the patient was having some ventricular escape beats.  But I learned that the patient had a pacemaker and that the 12 lead also showed a functioning pacemaker.  If the patient was having some escape beats then I would suspect a primary pacemaker failure.  3. Ventricular Paced Rhythm Ventricular Paced Rhythm.   The rhythm is regular.  The rate is 60. The PR interval is 20.  A pacer spike occurs before each QRS complex.   4. 100% ventricular paced with some demand atrial pacing. 5. Biventricular Pacing

EKG Rhythm Strips 22: Paced Rhythms

Identify the following paced rhythms: 1. 2. 3. 4.  5. Answers 1. Demand Atrial Paced Demand Atrial Paced.   There are no pacemaker spikes on the second and fourth complexes.  The P waves are the patient's own native P waves.  But on the other complexes a pacer spike preceeds each of the P waves.   It is not possible to determine the exact kind of internal pacemaker a patient has based on the rhythm.   This could be an example of an AAI pacemaker in which the atria are paced.  But when the pacemaker senses a native P wave it is inhibited from producing a paced beat.     2. Biventricular Paced Biventricular Paced.   Two pacemaker spikes precede the QRS complex.   One pacemaker spike for each ventricle.  A PVC is also present.  3. Demand AV Paced Demand AV Paced.   On the 1st and 7th complexes there are very small atrial spikes present.  On all the other complexes there are native P waves present wit
