Fig. 3From: Ionic mechanisms of ST segment elevation in electrocardiogram during acute myocardial infarctionEffects of transmural hyperkalemia and adenosine triphosphate (ATP) depletion on the electrocardiogram (ECG). a Simulated V2 lead ECGs under various concentrations of ATP and potassium are shown. ECGs with similar morphologies are grouped with different colors (mild: light blue; moderate: green; severe: light brown; arrhythmia: dark brown). b 12-lead ECGs of representative cases are shown. Conditions were selected from (a) for normal (black rectangle), mild ischemia (blue rectangle), moderate ischemia (green rectangle), and severe ischemia (red rectangle)Back to article page
