Electrogram of the Heart Intracavity

An intracavitary cardiac electrogram is a diagnostic method that provides an image of the electrical activity of the heart. This method is used to identify various disorders of the heart, such as arrhythmias, blockades, ischemic changes and others.

An intracavitary cardiac electrogram is performed using a special device - an electrocardiograph, which records the electrical activity of the heart. During the procedure, the patient lies on his back, his arms and legs should be relaxed. Electrodes placed on the patient's chest and arms record the electrical potentials that arise when the heart is beating.

The resulting intracavitary cardiac electrogram usually takes the form of a curve that displays the electrical activity of the heart over a certain period of time. A cardiologist analyzes this curve to identify possible problems with the heart. For example, if the electrogram shows changes in heart rate or the presence of arrhythmias, this may indicate a heart problem.

The advantages of an intracavitary cardiac electrogram include high diagnostic accuracy, the ability to detect early stages of cardiac dysfunction, and the ability to assess the effectiveness of treatment. However, like any other diagnostic method, intracavitary cardiac electrogram has its limitations, such as the need for special preparation of the patient and the presence of some contraindications.

In general, intracavitary cardiac electrogram is an important diagnostic method that can help identify various cardiac disorders in the early stages and provide more effective treatment.

The word “electrogram” began to be used in medicine after the discovery in the second half of the 19th century by the German physician R. Koch of the phenomenon of faradization - muscle contraction under the influence of electrical impulses. The term “heart electrogram” was first used by G. Land in 1885. At the beginning of the 20th century, L. Born and D. Winkelhacker established that the heart is contractile under the influence of external electrical stimuli, and V. A. Nedoshivin and I. I. Kharashkevich first reported the possibility of recording cardiac biocurrents using plate electro
