The Intracardiac Electrogram (IEGM) is a crucial diagnostic tool in cardiology, providing real-time insights into the electrical activity within the heart. This specialized recording captures the intricate patterns of electrical signals during each cardiac cycle, helping clinicians assess the heart's conduction system and identify abnormalities. By inserting catheters directly into the heart chambers, healthcare professionals can record these intracardiac signals, offering a detailed analysis of the heart's rhythm and identifying any irregularities or arrhythmias. The Intracardiac Electrogram plays a pivotal role in guiding therapeutic interventions, such as ablation procedures, and contributes significantly to the accurate diagnosis and treatment of various cardiac conditions.
