Abstract:
This manuscript was written in an effort to emphasize the points made by Porter et al. (Clin Cardiol 1997; 20:971-973). Right ventricular infarction may be erroneously interpreted as an anteroseptal infarction because of elevation of the S-T segments in leads V1-V4. The two can be separated when, using the Grant method of analysis, the S-T segments are represented as vectors: the mean S-T vector is directed inferiorly, to the right, and anteriorly when there is an inferior-right ventricular infarct, and superiorly, to the left, and anteriorly when there is an anteroseptal infarction. Other aspects of right ventricular infarction are also discussed.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
