Area of Science:
- Cardiology
- Medical Imaging
Background:
- Cardiac arrhythmias significantly impact patient morbidity, mortality, and quality of life.
- Identifying the underlying cause of arrhythmias is crucial for guiding treatment and predicting outcomes.
Purpose of the Study:
- To highlight the integral role of Cardiovascular Magnetic Resonance (CMR) imaging in diagnosing the aetiology of cardiac arrhythmias.
- To discuss the challenges and solutions for CMR imaging in patients with irregular heart rates.
Main Methods:
- Utilizing Cardiovascular Magnetic Resonance (CMR) imaging for non-invasive tissue characterization.
- Assessing CMR's accuracy and reproducibility in diagnosing conditions like myocardial infarction, cardiomyopathies, and congenital heart disease.
Main Results:
- CMR reliably diagnoses various cardiac pathologies underlying arrhythmias, often revealing substrates missed by conventional methods.
- Challenges exist in CMR acquisition for patients with irregular heart rates.
Conclusions:
- CMR is indispensable for determining arrhythmia aetiology, aiding treatment planning and prognosis.

Abstract:
Cardiac arrhythmias are associated with significant morbidity, mortality and poor quality of life. Cardiovascular magnetic resonance (CMR) imaging, with its unsurpassed capability of non-invasive tissue characterisation, high accuracy, and reproducibility of measurements, plays an integral role in determining the underlying aetiology of cardiac arrhytmias. CMR can reliably diagnose previous myocardial infarction, non-ischemic cardiomyopathy, characterise congenital heart disease and valvular pathologies, and also detect the underlying substrate concealed on conventional investigations in a significant proportion of patients with arrhythmias. Determining the underlying substrate of arrhythmia is of paramount importance for treatment planning and prognosis. However, CMR imaging in patients with irregular heart rates can be problematic. Understanding the different ways to overcome the limitations of CMR in arrhythmia is essential for providing high-quality imaging, comprehensive information, and definitive answers in this diverse group of patients.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
