Palpitation: causes, what to do and what to look for

term "tachycardia" brings together a variety of complaints of chest discomfort that patients themselves may also be called hitting, pushing, interruptions and so on. D. Patients may complain of palpitations as in violation of rhythm and conduction of the heart and other diseases.In some cases the heart - it is a symptom of life-threatening arrhythmias, so if these complaints require a thorough examination.

often called the heartbeat of emotional and physical stress.If there is fever and rapid pulse.If the heartbeat is not due to these reasons, it should be suspected arrhythmia.

most frequent arrhythmia - a sinus tachycardia, atrial and ventricular arrhythmias, atria

l fibrillation, supraventricular tachycardia.When
sinus tachycardia heart rate (HR) of 100-160 per minute.The main causes of sinus tachycardia - fever, emotional, and physical activity, increased anxiety.

Arrhythmia may not be an independent disease, but a consequence of many other diseases and conditions:

An increase in body temperature on 1˚S pulse rate of 10 beats per minute.

tachycardia during pregnancy is necessary for normal blood supply to the fetus and is associated with an increase in blood volume in the body of a woman.

menopausal women increases the likelihood of diseases of the heart muscle hormonal origin (non-ischemic).They manifest, in particular, palpitations.

to medicines that can cause heart rhythm disturbance, include antiarrhythmics, antidepressants, many diuretics, nitrates, cardiac glycosides, decongestants for the common cold, Salbutamol, Thyroxine.It

any conditions associated with lack of oxygen: stay in the highlands, lung disease, high content of carbon dioxide in the inhaled air, and so on. D.

This is a rare tumor of the adrenal gland.It is characterized by orthostatic tachycardia: heart rate when changing body position from horizontal to vertical is increased by more than 20 beats per minute.

middle-aged women may occur in conjunction with heart pain in the heart, is not typical of angina.Very often, this combination is a sign of mitral valve prolapse.This condition is detected by ultrasound of the heart (echocardiography).

heartbeat can be both a cause and a consequence of mental disorders.If organic and metabolic causes arrhythmia can not be identified, then eliminate anxiety disorders and depression.

Sometimes palpitations occur when someone from the family or friends of the patient suffers from severe heart disease (cardiophobia).
should also be remembered that patients with anxiety or depression fibrillation exacerbates mental disorders.

an important role in the diagnosis of arrhythmias playing history (history of the disease) and physical examination.It confirms the diagnosis by means of instrumental and laboratory methods.

Ask the patient to describe the heart attack, specify its duration, the accompanying sensations.Offer to tap out the rhythm of the heart, as it happens during a heart beat.If the patient is difficult to do this, the doctor himself tapping rhythms characteristic of various arrhythmias, and the patient chooses the one that is similar to his own.
chaotic rhythm characteristic of atrial fibrillation.Single strong reduction after a pause on the background of the right rhythm - a sign of arrhythmia (ventricular often).The sense of shock at the same time is not due to arrythmia, and following them heartbeats.
main questions that may ask the doctor:

Chest pain is observed in coronary artery disease and aortic stenosis, lack of air - the neuroses, mitral stenosis, heart failure.Dizziness and fainting - a manifestation of aortic stenosis and severe, life-threatening cardiac conduction disorders: sick sinus syndrome and complete atrioventricular block.

most informative physical (t. E. External) study conducted during tachycardia, but this is not always possible.The most important phase of the survey - study heart rate, which can perform and the patient during an attack.
heart rate above 150 per minute is typical for paroxysmal supraventricular tachycardia, atrial flutter or flicker and ventricular tachycardia, less than 150 per minute - for sinus tachycardia.The main causes of sinus tachycardia - physical activity, fever, hyperthyroidism, use of certain drugs.
be given to reinforcing bright eyes, a pronounced color, increase the neck, throbbing neck veins, increased blood pressure.Wet and warm hands could testify in favor of hyperthyroidism, pale - in favor of anemia.
detect signs of heart diseases, atherosclerosis, peripheral arterial disease.

Depending on the clinical doctor may prescribe the following studies:

Palpitations in children can be caused by emotional and physical stress, fever, cardiac arrhythmias and conduction.Require special attention paroxysmal supraventricular tachycardia, atrioventricular block and ventricular arrhythmias.

Older most common causes of heart - cardiovascular disease (ischemic heart disease, myocardial infarction, hypertension) and taking medicines, especially cardiac glycosides.
Extrasystole observed in 40% of the elderly, it usually does not require treatment.
Older sinus tachycardia or atrial fibrillation may be a manifestation of (sometimes the only) of hyperthyroidism.Additional diagnostic feature in this case - the sparkle in her eyes.

When complaints increased, palpitations, irregular heartbeat should contact a physician.He will have an initial examination, if necessary, direct to the cardiologist and other specialists.
The treatment of the following:
