Generality
Cardiac Holter is a type of electrocardiogram that allows constant monitoring of the rhythm and electrical activity of the heart, over a period of time with a canonical duration of 24-48 hours.
The examination - also known as ECG Holter or dynamic electrocardiogram according to Holter - uses a special battery-powered instrument, called a portable electrocardiograph.
If necessary, the investigation also makes it possible to evaluate the effectiveness of a pharmacological treatment, undertaken for a certain heart disease, or the operation of devices (pacemakers, cardioverter defibrillators, etc.) previously implanted in the heart of the patient examined.
The installation of the portable electrocardiograph is a quick and painless procedure, which involves the application on the chest of some metal plates, called electrodes.
