Key result
Body surface potential mapping is a more sensitive method than traditional ECG for diagnosis, particularly in the early phase of non-ST elevation myocardial infarctions.
Why the study?
Does body surface potential mapping improve diagnostic sensitivity compared to traditional ECG in patients with obesity?
Does body surface potential mapping improve diagnostic sensitivity compared to traditional ECG in patients with obesity?
Body surface potential mapping may offer greater diagnostic sensitivity than traditional ECG for detecting early NSTEMI in obese patients.
May support BSPM over ECG for early NSTEMI detection in obesity; hypothesis-generating and requires prospective validation.
BACKGROUND: Various ECG abnormalities are commonly observed in obesity and in metabolic syndrome. SUMMARY: Some of these abnormalities are caused by the pushed-up position of the diaphragm due to obesity and others occur as a result of the complications of the condition. The position of the R wave may change, various arrhythmias may develop or the QT interval may be prolonged, which increases the tendency to malignant arrhythmias. In obesity, the ECG signs of ventricular hypertrophy are less informative due to the accumulation of epicardial and subcutaneous adipose tissue. In general, it can be concluded that a microcirculation disorder is present in metabolic syndrome that may primarily be associated with ST-T wave abnormalities. KEY MESSAGES: Body surface potential mapping is a more sensitive method than traditional ECG with potentially greater use for diagnosis mainly in the early phase of non-ST elevation myocardial infarctions.

Gábor Simonyi (2014) conducted a review in Obesity and metabolic syndrome. Body surface potential mapping vs. Traditional ECG was evaluated. Body surface potential mapping is a more sensitive method than traditional ECG for diagnosis, particularly in the early phase of non-ST elevation myocardial infarctions.
