*If the paper speed is 25 mm/second, there will be 1500 mm/minute, thus the heart rate is 1500 ÷ distance between two complexes.  

*If the paper speed is 25 mm/second, there will be 1500 mm/minute, thus the heart rate is 1500 ÷ distance between two complexes.  

*Using the formula in this case, the heart rate is estimated to be 100 beats per minute.

There are no visible P waves and the QRS complexes are wider than they should be (around 0.06 seconds; normal QRS duration is <0.04 seconds). <br><br>

It is also important to check the traces from other leads for presence of P waves.

Escape rhythms are characterized by their slow rate and wide QRS complexes and they occur when the normal pacemaker tissue fails to discharge for a prolonged period. <br><br>

Ventricular escape rhythms originating in the tissues closest to the atrioventricular node (junctional escape complexes) appear most like normal QRS complexes, as in this example.
