Abstract:
Systematic national effort to improve cardiac electrophysiology practice in Lebanon is lacking, and the quality improvement program mainly relates to individual efforts along with regulations, which are set as a "Road Map" by the Lebanese Arrhythmia Working Group. Lebanon currently has five electrophysiology laboratories. The "Road Map" mainly consists of creating a registry and a National Card for Electronic Device Holder, centralization of complex electrophysiology procedures in institutions where electrophysiologists are available, setting regulations to conform to international guidelines, and creating a National Arrhythmia Website and E-Journal. Most importantly, we emphasize that the practice of device checking must be performed by physicians with expertise and not by industry technicians.

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.
