The combined use of esophageal electrocardiogram and multiple right parasternal chest leads in the diagnosis of PSVT and determination of accessory pathways involved: A new simple noninvasive approach

ECGe + RPCL can be used as a reliable noninvasive diagnostic tool to identify the nature of tachycardia and the pathways involved in the reentrant ring of PSVT especially in those with multiple atrioventricular accessory pathways or a combination of atrioventricular accessory pathways and dual atrioventricular nodal pathway.
