Abstract:
Electromyography and nerve conduction studies are the primary electrodiagnostic studies employed in the evaluation of patients with weakness and suspected myopathy. This article discusses the physiologic principles that serve as a framework for understanding the purpose, limitations, and interpretation of these tests. In the process the authors also review the differential diagnosis of myopathy.

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.
