Extrasystole Blocked

Blocked extrasystole: what is it and how does it affect the heart

Blocked extrasystole is a type of arrhythmia that is associated with conduction disturbances in the nervous system of the heart. This type of arrhythmia manifests itself in the form of atrial extrasystoles, in which excitation occurs in the atria, but the ventricles of the heart do not contract. This occurs due to the refractoriness of the cardiac conduction system bundle, which connects the atria and ventricles, after a previous excitation impulse.

Symptoms of blocked extrasystoles can range from mild to severe. Some people may not notice symptoms, while others may experience skipping heartbeats or abnormal heart rhythms. In more severe cases, a blocked extrasystole can lead to heart failure, which may require medical intervention.

Electrocardiography (ECG) may be required to diagnose blocked extrasystoles. This is a procedure in which electrodes are attached to the skin on the chest and record the electrical activity of the heart. If the ECG shows the presence of a blocked extrasystole, then additional examination may be required to determine the causes of this arrhythmia.

Treatment for blocked extrasystoles depends on its cause and severity. In some cases, treatment is not required, since a blocked extrasystole does not pose a threat to health. If the symptoms of a blocked extrasystole lead to serious problems, then medications may be prescribed to control the heart rhythm or regulate the conductivity of the heart.

In conclusion, blocked extrasystole is a type of arrhythmia that is associated with a disturbance in the conduction of the nervous system of the heart. This type of arrhythmia can lead to a variety of symptoms, including skipped heartbeats and irregular heart rhythms. Treatment for blocked extrasystoles depends on its cause and severity, and may include drug therapy or other methods aimed at regulating heart rhythm and cardiac conduction. If you have symptoms of blocked extrasystoles, contact a qualified healthcare professional for diagnosis and treatment.

Extrasystole blocked

A blocked extrasystole is an atrial extrasystole in which there is no subsequent contraction of the ventricles of the heart. This is due to the refractoriness (non-excitability) of the His bundle, which connects the atria and ventricles, after previous excitation.

With extrasystole, a premature ectopic impulse occurs from the atria. This is usually followed by ventricular contraction. However, if the His bundle is in a refractory state after previous excitation, then it cannot conduct an impulse to the ventricles. Thus, the atrial extrasystole remains isolated, without causing ventricular contraction.

On an ECG, a blocked extrasystole is recorded as a premature P wave without a subsequent QRS complex. The PQ interval is shortened compared to sinus rhythm. Blocked extrasystoles more often occur with organic lesions of the conduction system of the heart.
