To facilitate correct diagnosis and guide management, the authors use a consistent sequence to explain the ECG abnormalities for each site of coronary occlusion. A schematic of the coronary tree illustrates the point of occlusion.
The second part of the book contains a self-assessment section with a series of 15 cases, each of which includes one or more 12-lead ECGs for analysis. These valuable examples help you prepare for on-the-spot interpretation in the emergency department or intensive care unit.
1 The heart walls and coronary circulation.
The heart walls and their segmentation: The importance of uniform nomenclature.
Coronary circulation: The perfusion of the heart walls.
2 The ECG changes in ST elevation myocardial infarction.
3 The concept of injury vector: direct and reciprocal patterns.
4 Clinical interpretation and significance of ST changes.
Location of the occlusion and risk stratification: the role of deviations of the ST-segment.
1. From the occluded artery to the area at risk and thecorresponding electrocardiographic abnormality.
2. From the electrocardiographic pattern to the occluded artery and the area at risk.
Other characteristics of ST elevation regarding prognosis.
ST changes in patients with ischemia due to multivessel occlusion.
