An electrogram is a graphic record of the electrical activity of the heart captured by electrodes positioned inside or on the surface of the heart. Used in electrophysiological studies and cardiac monitoring, electrograms provide critical insights into cardiac arrhythmias and guide therapeutic interventions such as ablation therapies.
Cardiac electrophysiology is the study of the electrical properties and activities of the heart, crucial for understanding arrhythmias and guiding treatments like ablation and pacemaker implantation. It involves analyzing the heart's electrical conduction system to diagnose and manage disorders that affect heart rhythm and function.
An electrocardiogram (ECG) is a non-invasive test that records the electrical activity of the heart over a period of time, providing crucial information about heart rhythm and function. It is widely used to detect irregularities in heartbeats, diagnose heart conditions, and monitor the effectiveness of treatments for heart diseases.
Electrode placement is crucial in ensuring accurate and reliable recordings in various biomedical applications, such as electrocardiograms (ECG) and electroencephalograms (EEG). Proper placement involves understanding anatomical landmarks and standardized positions to minimize noise and maximize signal fidelity.
Cardiac arrhythmias are disturbances in the heart's electrical activity that can lead to irregular heartbeats, affecting the heart's ability to pump blood effectively. They can range from harmless to life-threatening, requiring careful diagnosis and management to prevent complications such as stroke or heart failure.
Heart rhythm monitoring is a critical diagnostic tool used to detect and analyze irregularities in the heart's electrical activity, enabling early identification and management of potential cardiac conditions. It employs various technologies, from wearable devices to advanced hospital-based systems, to provide continuous or intermittent surveillance of heart rhythms.
Signal processing involves the analysis, manipulation, and synthesis of signals such as sound, images, and scientific measurements to improve transmission, storage, and quality. It is fundamental in various applications, including telecommunications, audio engineering, and biomedical engineering, where it enhances signal clarity and extracts useful information.
An electrophysiology study (EPS) is a medical test used to assess the heart's electrical system and activity to diagnose abnormal heart rhythms, or arrhythmias. By triggering and analyzing electrical impulses within the heart, doctors can determine the precise location and details of the abnormality, guiding potential treatment choices such as ablation or medication.
