Abstract Genetic mapping studies have identified thousands of associations between common variants and hundreds human traits. Translating these into mechanisms is complicated by two factors: they fall gene regulatory regions; are rarely mapped to one causal variant. One way around limitations find groups traits that share associations, using this genetic link infer a biological connection. Here...

avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. there...
