DOI: 10.1016/j.hrthm.2018.04.013
Abstract: BACKGROUND Atrioventricular (AV) block is usually due to infranodal disease and associated with a wide QRS complex; such patients often progress to complete AV block and pacemaker dependency. Uncommonly, infranodal AV block can occur within… read more here.

DOI: 10.1016/j.ipej.2021.01.008
Abstract: A 35-year-old gentlemanwith manifest preexcitation consistent with right posterolateral accessory pathway underwent EP study for recurrent palpitation. In view of underlying preexcitation the most likely diagnosis entertained for the narrow QRS tachycardia is an orthodromic… read more here.
