Accordingly, the incomplete AV dissociation is due to high-grade second degree AV block, and the overall ventricular rate of only 41/min is the cause of the patient's weakness and presyncope.
[12] in 2008 reported a case of MG who presented with syncope caused by pyridostigmine induced high grade AV block. Patient was treated with hyoscyamine resulting in reversal of AV block and thus avoiding pacemaker placement.
First degree AV block manifests as a prolongation of the P-R interval and often needs no treatment apart from careful monitoring.
