Complications were found to be cardiogenic shock, ventricular arrhythmias and atrio-ventricular block.
The patient's ECG is consistent with SVT associating rate-dependent LBBB which is common in orthodromic atrio-ventricular reentry tachycardias [3].

Moreover, the risk for atrio-ventricular block is dramatically reduced due to the supra annular positioning of Trinity," added Christian Hengstenberg, M.D., cardiologist at the German Heart Center in Munich.
The effects of heart rate on myocardial velocity and atrio-ventricular displacement during exercise with and without beta-blockade: a tissue Doppler echocardiographic study.
Heart rate variability (HRV) is a measure of the balance between sympathetic mediators of heart rate that is the effect of epinephrine and norepinephrine released from sympathetic nerve fibres acting on the sino-atrial and atrio-ventricular nodes which increase the rate of cardiac contraction and facilitate conduction at the atrio-ventricular node and parasympathetic mediators of heart rate that is the influence of acetylcholine released by the parasympathetic nerve fibres acting on the sino-atrial and atrio-ventricular nodes leading to a decrease in the heart rate and a slowing of conduction at the atrio-ventricular node.
The Atrio-ventricular (AV) valves of fetal heart from group A showed various malformations like, thinning and fusion of the leaflets.
In patients with heterotaxy (with polysplenia), there is a high incidence of congenital cardiac disease (3) and particularly atrial septal defects, atrio-ventricular canal defects or abnormal pulmonary venous return.
(10,11) Axial imaging has disadvantages in congenital heart diseases where the cardiac axis and the skeletal axis may not align, leading to inaccuracies in delineating the atrio-ventricular plane.
