Examinations
Heart rhythm disorders require rigorous and personal case-by-case management, based on a series of diagnostic examinations. In this section, we describe in detail the various tests used to evaluate and monitor these medical conditions. Each examination plays a crucial role in developing an accurate diagnosis and formulating an appropriate treatment plan.

Myocardial scintigraphy
Myocardial scintigraphy (also called myocardial perfusion imaging) is a medical imaging test used to analyze the functioning and vascularization of the heart by injecting a tracer (a low-level radioactive product). This product is not harmful to the patient’s health. The tracer, injected intravenously, is absorbed by the various structures of the heart and releases radiation…

Holter monitor, continuous monitoring of the heart
The terms ECG or EKG device and heart monitor are frequently used by physicians to refer to a Holter monitor. A Holter monitor is a medical device used to continuously monitor the electrical activity of the heart over an extended period of time. This non-invasive examination continuously records all of the heartbeats over a 24-to-72-hour…

Transesophageal echocardiography (TEE)
The abbreviation TEE is often used by the medical profession for this examination. An echocardiogram, or cardiac ultrasound, is an imaging test that uses ultrasounds produced by a probe. When ultrasounds come into contact with a structure in the body, they produce echos that are specific to the surface encountered. The probe is linked to…

Transthoracic echocardiography (TTE)
TTE is a term often used by physicians to refer to transthoracic echocardiograms or cardiac ultrasounds. Patients will often see or hear this abbreviation. Ultrasonography is an imaging test that uses ultrasounds produced by a probe. When ultrasounds come into contact with a structure in the body, they produce echos that are specific to the…

Stress testing with and without washout
What are the differences between stress testing with and without washout? A stress test or stress electrocardiogram is a screening and prevention examination. It measures cardiac electrical activity using an ECG during ongoing physical exercise and detects any electrical abnormalities. This examination is carried out during a standardized test on a treadmill or a specific…

Electrocardiogram (ECG or EKG)
Each heartbeat is represented by an electrical impulse (or wave) that travels through the heart muscle, enabling the heart to contract and pump blood towards the organs. An electrocardiogram, also called an ECG or EKG, is a clinical test that records and measures the electrical activity of the heart. This test is done to assess…

Genetic testing
Heart rhythm disorders may be caused by various factors. Among these, genetics play a key role in a wide range of pathologies. Certain inherited abnormalities, passed down within families, can affect the structure and functioning of cardiac cells, thereby increasing the risk of developing potentially serious arrhythmias. Nowadays, the study of these genetic predispositions can…

MRI
An MRI, magnetic resonance imaging, is a radiological examination using a high-power magnetic field. Specifically, this non-invasive technique, which is not based on exposure to radiation, is used to visualize and examine soft tissues, the brain, spinal cord, muscles, joints and internal organs. A cardiac MRI can detect heart problems early-on, especially in areas with…

CT scans
A CT scan, also called a CAT scan, is a radiological examination that uses X-rays to obtain detailed images of the inside of the body. Using the information collected, a computer then reconstructs an image in two or three dimensions. CT scans thus enable the detailed observation of organs, soft tissues, bones and blood vessels.…
