EKGs provide information about heart rate, heart rhythms and provide some data on underlying myocardium, valves and coronary vessels. EKGs can be used to aid in the diagnosis of myocardial infarction, arrhythmia, left ventricular hyptertrophy, valvulopathies, and coronary artery disease.
Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.
People who have a normal ECG and who are able to exercise, for example, do not merit routine imaging. [13] Imaging tests such as stress radionuclide myocardial perfusion imaging or stress echocardiography can confirm a diagnosis when a person's history, physical exam, ECG and cardiac biomarkers suggest the likelihood of a problem.

Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...
An ST elevation is considered significant if the vertical distance inside the ECG trace and the baseline at a point 0.04 seconds after the J-point is at least 0.1 mV (usually representing 1 mm or 1 small square) in a limb lead or 0.2 mV (2 mm or 2 small squares) in a precordial lead. [2] The baseline is either the PR interval or the TP interval ...
An example of an ECG tracing typical of uncommon AV nodal reentrant tachycardia. Highlighted in yellow is the P wave that falls after the QRS complex. Specialty: Cardiology: Symptoms: Palpitations, chest tightness, neck pulsation: Diagnostic method: electrocardiogram, electrophysiological study: Differential diagnosis
The various components of a normal, healthy ECG tracing. As a result of underlying heart disease, this cardiac conductive tissue can become damaged from ischemia (a deprivation of oxygenated blood). This damage results in the inability of this neural-like tissue to conduct electrical signals and control the heart as efficiently as before ...
