0% of patients in the Zio monitored group were found to have potentially actionable arrhythmias other than AF including ventricular tachycardia, pause, AV block
, and symptomatic supraventricular tachycardia.
The patient received a permanent pacemaker due to complete AV block
The 2008 ACC/AHA/HRS Guidelines for device-based therapy acknowledge that, in cases of third-degree AV block
complicating inferior wall MI, permanent pacing should be reserved for patients in whom the block does not resolve with revascularization7.
We report a FM child who developed grade III AV block
after the treatment of ECMO, and was put on permanent pacemaker.
We did not face with any major complication except in one patient: complete AV block
was seen one month after the procedure.
The AV block
is most likely the result of bilateral bundle branch block, with complete block in the right bundle and 2:1 block in the left bundle.
He pointed out that VA conduction does not mean AV block
On the following days he remained dependent of the pacemaker due to persistent AV block
The patient was a 72-year-old male who presented to our emergency room with AAAD with right ventricular failure and complete AV block
before the operation.

Except for the dead patient, none of them had complete AV block
Transient AV block
developed in 3 patients which was recovered lately, while complete heart block occurred in 4 patients which required insertion of permanent pacemaker device.
