 {{Information
-|Description = This is an example of time dependent capture. The native QRS complexes are small (and grow larger due to the auto gain control on this recorder), and the rhythm is probably a nodal escape with sinus arrest. The pacer is a dual chamber where the atrial lead captures but the ventricular lead captures only if it falls close to a T wave of one of the native escape beats.
+|Description = This is an interesting example of time dependent capture. Note the the venticular pacemaker captures for several beats but then fails to capture. Capture is restored when the pacer spike falls near to a conducted sinus beat.
+The underlying rhythm shows a lengthening of the pr interval before a p wave fails to conduct. This suggests a Mobitz I A/V block.
