Abstract:
Brugada syndrome is often electrocardiographically characterised by ST-segment elevation in the right precordial leads. The characteristic Brugada electrocardiogram pattern is often dynamic and concealed, and may be revealed during febrile states or under the challenge of drugs that have a sodium channel-blocking effect. In this report, we describe two cases of exposure of the Brugada electrocardiogram pattern during febrile states. When the patients' body temperature decreased and before the ST-elevation disappeared, ST-segment and T-wave alternans in the right precordial leads were observed, especially in lead V2.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

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.
