What kind of procedure is used to diagnose atrial and ventricular arrhythmias non-invasively?

The appropriate procedure for diagnosing atrial and ventricular arrhythmias non-invasively is electrophysiology. Electrophysiological testing involves evaluating the electrical function of the heart, helping to identify the nature and origin of arrhythmias. This can be achieved through techniques such as Holter monitoring or event recorders that record the heart’s electrical activity over a period, allowing for the detection of irregularities without the need to insert any instruments into the body.

Other imaging techniques, such as X-rays, ultrasound, or CT scans, primarily provide structural information about the heart rather than detailed insights into its electrical activity. While these methods can help identify some related conditions, they do not specifically diagnose arrhythmias the way electrophysiology can. Therefore, electrophysiology is uniquely suited for this purpose, making it the correct choice for non-invasive arrhythmia diagnosis.
