Heart rhythm disorders: exams

To analyze a cardiac rhythm disorder, the first test to be performed is an ECG (electrocardiogram) that allows the recording of electrical waves that travel through the heart. This is a common exam performed by doctors when they suspect a heart condition and especially a rhythm disorder.

Electrodes (pellets and bracelets) are placed on the chest and at the end of the 4 limbs with the application of a gel to facilitate the conduction of the current. They are connected to a device that records the electrical activity of the heart.

An electrocardiographic plot is obtained: it is represented by several curves which objectify the conduction of the electric current at different places of the heart.

ECG can often be used to diagnose a rhythm disorder or a heart condition, such as atrial fibrillation, atrioventricular block, myocardial infarction, when the electrical current does not pass where the necrosis is located.

It is also possible to record the electrical activity of the heart by a probe mounted inside the heart: the electrophysiological study makes it possible to trace very precisely the path of the electric current in the heart, and to discover for example an electric circuit unnatural. Some abnormal circuits can be destroyed by radio frequency and healing will be final.

Heart rhythm disorders are not always permanent and to highlight them, it is possible to practice an ECG Holter: it is a recording of the electrical activity of the heart 24/24.

Chondrocalcinosis: the symptoms

The symptoms of chondrocalcinosis are very close to those of gout, which is why chondrocalcinosis is called pseudo-gout. Symptoms include: sudden and very intense pain in a joint, redness, inflammation, swelling of the affected area. In principle, chondrocalcinosis attacks are punctual and spaced, but some patients experience permanent discomfort

Dyspraxia: treatments

Treatments for dyspraxia, except if it is very moderate, are multidisciplinary, that is to say that they involve different trades care or education. Before proposing treatments, dyspraxia must be confirmed by a neuropsychological and psychomotor assessment. This assessment will also make it possible to look for the presence of other disorders such as: dyslexia, dysphasia, dyscalculia, attentional disorder with or without hyperactivity, Asperger syndrome
