bradycardia and pregnancy - usually a combination of harmless and occurs without any additional violations of the cardiovascular system.However, bradycardia and may be a sign of serious disorders, such as myocarditis.Therefore, a pregnant woman examined and treated if necessary.
bradycardia during pregnancy - the types and causes of
During pregnancy the cardiovascular system of women has a significant load, so the heart rate (HR), she usually increases.But it also happens that, during the pregnancy rate decreased heart rate, that is developing bradycardia.It is not always a sign of severe disease and more often than not accompanied by unpleasant symptoms.
heart muscle is able to automatically shrink under the influence of impulses arising in itself.This automaticity provides conduction system of the heart - special muscles that run along the entire thickness of the heart, forming branches (beams) and clumps of cells (units).Cardiac conduction system consists of nodes located in the atriu
sinus bradycardia is divided into (it may be a variant of normal) when the slow main pacemaker (the place where there are impulses) - sinus node and bradycardia bradycardia - when the heart stops as a result of violation (blockade) of cardiac conductionrhythms at different levels (between the sinus node and atrium, or between the atria and the ventricles).
Sinus bradycardia during pregnancy
If the sinus node has an innate low automatism, the sinus bradycardia during pregnancy can be a normal variant.Such a woman from birth adapted to precisely this rhythm without any damage to health and her pregnancy is proceeding normally.
But sometimes develops during pregnancy abnormal sinus bradycardia.The reason it is often the irritation or compression of the vagus nerve (vagus nerve - cranial nerve, which runs through the chest and abdomen) growing uterus.The inhibitory effect on the sinus node may also have some of the chemicals, pharmaceuticals, as well as inflammatory and metabolic diseases of the heart muscle (myocarditis, myocardial dystrophy, coronary heart disease).
pulse when sinus bradycardia Sinus bradycardia - how to distinguish normal from pathological state rare in pregnant women (60-70 beats per minute), but rhythmic.Sinus arrhythmia Arrhythmia - when we hear his heart almost never causes a marked disorders of the heart and unpleasant sensations in the field.Sinus bradycardia during pregnancy does not worsen the condition of patients and does not constitute indication for its interruption.
bradycardia pregnancy with heart blockages
impulse conduction in the heart muscle may be disturbed in their transition to the atria or ventricles.Violation conductivity between the sinus node and atrium called the sinus block, it does not reach all the impulses of the heart muscles of the atria and ventricles.The reason for this blockade can be any disease of the heart muscle.If a pregnant woman feels with the attack of dizziness or weakness, then it can be removed by drinking a cup of freshly brewed tea.
If bradycardia in pregnant women, developing on the background of cardiac conduction between the atria and ventricles (atrioventricular block), the pulse is even more rare, there are arrhythmias (atrial and ventricles in a different mode).Women can disturb weakness, dizziness and fainting semiconscious.
When significant bradycardia in pregnant women suffering primarily the brain due to insufficient supply of oxygen and nutrients.This state is called the syndrome of Morgagni-Adams-Stokes and first manifested dizziness Dizziness - if the ground is slipping from under his feet (all spinning in the dark eyes) and then loss of consciousness, a temporary cardiac arrest and respiratory depression, convulsions and involuntaryurinating.After a while, the work of the heart is restored and the woman regains consciousness (what happened to her, she does not remember).
Diagnosis and treatment of bradycardia during pregnancy
resistant bradycardia with the appearance of attacks of weakness requires examination of pregnant women.Problems with childbearing occurs only in severe organic heart disease, accompanied by significant violations of state women, including seizures of Morgagni-Adams-Stokes and blood circulation.The management of pregnancy and childbirth in this case is carried out on an individual plan.
In most cases, bradycardia in pregnant does not require treatment.But such a woman should always be supervised by a doctor.
