Premature ventricular contraction
Premature ventricular contractions are excessive, abnormal contractions that originate from the lower chambers of the heart, the ventricles. This extra beat interferes with the heart's normal rhythm, which is manifested in the patient by heart flutters and strange sensations. Premature ventricular contractions are common, almost everyone will experience premature ventricular contractions at some point.
Premature ventricular contractions are also known by these names:
- Premature ventricular complex
- NPK
- Premature ventricular impulse
- Extrasystole
If premature ventricular If premature ventricular contractions are common and you have heart disease, you will need treatment to help you feel better and prevent heart complications.
The heart consists of four cells - two upper atria and two lower ventricles The rhythm is normally controlled from the sinoatrial node, which is located in the right atrium and consists of a cluster of specialized cells.
The sinoatrial node begins to generate an impulse and the process ends with contraction From the sinus node, an electrical impulse travels from the atria to the ventricles, causing the ventricles to contract and pump blood.
Premature ventricular contraction is a pathological contraction, the impulse of which comes from the ventricles This extra contraction often occurs earlier than the next beat is expected Premature ventricular contractions often interfere with the normal sequence of heart contractions: the atria should contract first, then the ventricles Because of this, excessive strokes will not pump enough blood through the body
Why does excessive compression occur? The reason is not always known Certain factors, such as heart disease, changes in the body that make the ventricular cell electrically unstable, may play a role. Heart disease and scarring in the heart can cause improper impulse transmission
Premature ventricular contractions are associated with:
- Chemical changes, imbalances in the body
- Certain medications, including asthma medications
- Alcohol or drugs
- High levels of adrenaline in the body caused by caffeine,
Premature ventricular contractions sometimes cause no symptoms You may have a strange feeling in your chest:
- Throbbling
- Flying
- Speeding, jumping
- Missing beats
- Feeling a better heartbeat
When to refer Your doctor will determine exactly what is causing your symptoms Premature ventricular contractions can be a problem, but often the cause is another condition, such as arrhythmia, heart disease, anxiety, anemia, or infections.
