What is a tachycardia. Causes, treatment of this symptom

A Normal paced heart rate in adults is determined in the range of 60 - 80 beats per minute. Tachycardia - increased heart rate over 80 per minute. The sinus node does in the body role as the main regulator of heart rate. By increasing the activity of the sinoatrial node under the influence of various external and internal factors develops sinus tachycardia, causes, treatment of which is discussed below.

Sinus tachycardia-causes, diagnosis, treatment

Sinus tachycardia is often not associated with heart disease and is determined under different physiological and pathological conditions. It can be caused by emotional stress, exercise, fever. A well-known relationship between the frequency of heartbeat and body temperature-when the temperature increases by 1C the heart rate increased by 6-10 beats per minute. Pathological sinus tachycardia happens when the heart failure of different origin.

The opposite sinus tachycardia is called sinus bradycardia. This is defined as heart rate less than 60 contractions  per minute. Bradycardia develops as a result of lower activity of the sinus node.

These simple heart rhythm disorders do not have much diagnostic value. ECG in these narushena rhythm a little different from the norm. Treatment is symptomatic, treatment depends on the causes that led to the disruption of sinus node automaticity.

What is paroxysmal tachycardia, causes, treatment of this condition will be discussed below.

Paroxysmal tachycardia are bouts of palpitations in which the heart rate reaches 150 - 220 beats per minute with the correct rhythm. They usually begin and end suddenly. Paroxysmal tachycardia, causes, treatment can be different, as it is divided into atrial and ventricular.

Paroxysmal atrial tachycardia often occurs in healthy people with unstable nervous system. Very often the attacks happen after emotional stress, abuse of these drinks like strong tea, coffee, and alcohol. These factors increase the excitability of the nervous system and contribute to the development of increase in heart rate.

Paroxysmal supraventricular tachycardia is often caused by the reflex effect on the heart in different diseases of internal organs. The attack may be the result of hormonal imbalance during pregnancy, menopause.

In V-form usually occurs in severe organic heart disease (coronary artery disease, especially acute myocardial infarction, myocarditis, hypertension).

Patients during the seizure complain of the sudden appearance of palpitations. You may experience feeling of heaviness in the heart area and pain type of angina. Sometimes there is nausea, vomiting. Paroxysmal tachycardia often accompanied by General weakness, feeling of fear, sometimes dizziness, fainting.

During the inspection, you can determine the expressed paleness of skin, and with continued attack - acrocyanosis, increased pulsation of vessels of neck. The rhythmic pulse frequent, small filling. HELL most reduced.

Diagnosis of paroxysmal tachycardia is performed based on the data of the ECG.

The Attack supraventricular tachycardia possible to stop the actions directed on stimulation of the vagus nerve. This can put pressure on the eyeballs, squeeze abdominals, induce vomiting, to ask the patient to push, hold breath. The ineffectiveness of the use of antiarrhythmic drugs. in severe conduct cardiac stimulation and electro therapy. Ventricular tachycardia is treated by parenteral introduction of antiarrhythmic drugs, administered EIT.
