Abstract:
The present case report is of a 36-year-old man who had been symptomatic for frequent palpitations for 4 years after a prolonged febrile episode. The electrocardiogram on admission revealed an iterative supraventricular tachycardia at rate of 110 bpm, with ventriculoatrial interval of 180 ms and superior P-wave axis. Electroanatomic mapping showed substantially normal values in the right atrium other than an area along the posteroseptal region of the tricuspid annulus, with a low-voltage region that correlated with the area of earliest activation.

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.
