Multichannel  ECG  body  surface  mapping  consists  of  synchronously  recording unipolar electrocardiograms at a variety of points on  the surface of  the chest, visually depicting the  ECG  recording  results  in  the  form  of  isopotential  and  other  isoparametric  maps,  and diagnostically  interpreting  them. ECG body  surface mapping  finds its limited use in diagnostics of heart  rhythm irregularities, predictions of life-threatening  ventricular  tachyarrhythmias,  and  in IHD.

ECG  body  surface  mapping  methodology  is considered being more informative than  standard electrocardiography  in  12  leads. However,  its  diagnostic  value  is  inferior  to  that  of  epicardial mapping  based  on  the  solution  to  the  inverse  electrocardiography  problem.

ECG  body  surface  mapping  methodology  does  not  require a CT or MRI study of the heart, since a mean model of the human torso is used for mapping,.

Indications for ECG Body Surface Mapping 

Diagnosis of Heart Rhythm Irregularities

  • Rough topical  diagnosis  of accessory atrioventricular  connections  associated  with  symptomatic WPW syndrome.
  • Rough topical diagnosis of atrial and ventricular arrhythmias.
  • Prognosis of the origination of life-threatening ventricular tachyarrhythmias.
  • Limited research application in electrophysiological mechanisms of atrial  flutters and fibrillations

Contraindications for Body Surface Mapping 

  • Excoriation of the skin integuments on the chest surface.
  • Skin diseases.
  • Allergic  reactions  to  the disposable ECG  recording  electrode  components  that    contact  the skin.
