Abstract:
A positive endomyocardial biopsy (EMB) is a major diagnostic criterion for arrhythmogenic right ventricular cardiomyopathy (ARVC). Nevertheless, its sensitivity is low due to the focal nature of the disease. Moreover, myocardial samples are usually taken from the uncommonly involved interventricular septum to minimize the risk of perforation. In this report, we describe a novel bioptical approach for ARVC diagnosis guided by the identification of right ventricle (RV) affected regions by means of electroanatomical voltage mapping.

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.
