Overview
There are no ECG findings associated with heartburn.
The ECG may be useful in the diagnosis of cardiac causes of heartburn such as acute coronary syndromes.
Electrocardiogram
- There are no ECG findings associated with GERD. However, EKG can be performed in cases of GERD that present with atypical chest pain that can mimic angina pectoris pain.[1]
- In case of heartburn due to acute coronary syndromes, the 12 lead ECG is used to classify patients into one of three groups:
- Those with ST segment elevation or new bundle branch block (suspicious for acute injury and a possible candidate for acute reperfusion therapy with thrombolytics or primary PCI),
- Those with ST segment depression or T wave inversion (suspicious for ischemia), and
- Those with a so-called non-diagnostic or normal ECG.[2]
A normal ECG does not rule out the presence of acute myocardial infarction. Sometimes the earliest presentation of acute myocardial infarction is instead the presence of a hyperacute T wave.[3] In clinical practice, hyperacute T waves are rarely seen, because they exists for only 2-30 minutes after the onset of infarction.[4] Hyperacute T waves need to be distinguished from the peaked T waves associated with hyperkalemia.[5]
ST Elevation
The electrocardiographic definition of ST elevation MI requires the following: at least 1 mm (0.1 mV) of ST segment elevation in 2 or more anatomically contiguous leads.[2] While these criteria are sensitive, they are not specific as thrombotic coronary occlusion is not the most common cause of ST segment elevation in chest pain patients.[6]
ST Depression
ST depression in the anterior leads might either represent reciprocal changes on EKG[7] or might be pathologically caused by either anterior ischemia in the context of a patent artery[8] or posterior infarct due to the complete occlusion of a coronary artery.[9]
