The electrocardiographic diagnosis of a variety of cardiac diseases, such as ischemia or infarction, pericarditis, and conduction disturbances, is based upon certain characteristic findings. However, none of these findings alone is usually pathognomonic for a particular disease.
This topic presents a series of tables that list the major causes of a number of common findings and abnormalities [1-4]. Their differential diagnosis is discussed in detail in the appropriate topic reviews.
●Q waves (table 1)
●ST segment elevations (table 2)
●Low QRS voltage (table 3)
