Paroxysmal Atrial Tachycardia

Paroxysmal atrial tachycardia – during tachycardia, the heart beats very fast and suddenly contract, up to 140-220 beats per minute. These episodes can last a few seconds to several hours. They stop as suddenly as they appeared.

Paroxysmal tachycardia can occur at young people too and can last a lifetime. After a crisis, the patient feels tired but this type of arrhythmia is rarely dangerous. Still require medical consultation because it can decrease quality of life.

Tachycardia atrial paroxysmal is one of those forms which show a sudden onset and end. Persist from several seconds to several days.

Paroxysmal atrial tachycardia is most common in people with heart disease organic chronic ischemic heart disease, myocardial infarction, administration of drugs (especially digoxin).

Paroxysmal junction tachycardia occurs most frequently in a normal heart.

Diagnosis is made by analyzing the ECG route. In paroxysmal atrial tachycardia, atrial depolarization P waves have normal shaft and paroxysmal junction tachycardia in DII are negative and positive in aVR. In most cases, however, atrial depolarization waves are not seen on the ECG, the QRS complexes overlap. Also, the two forms of tachycardia are similar in terms of mechanism, heart rate and treatment.

Diagnostic criteria for paroxysmal atrial tachycardia ECG are:

• regular rhythm

• frequency between 140-220 / minute

• Usually all atrial depolarization waves are transmitted to the ventricles (Drive 1 / 1)

• QRS complexes resemble those of sinus rhythm

• Isoelectric line is kept steady

Onset is sudden, rapid and irregular. Patient experiences palpitations, shortness of breath, faintness, anxiety. Most often the symptoms are reduced.

Atrial tachycardia paroxysmal is also called paroxysmal supraventricular tachycardia or fibrillation (TPSV).

Many patients do not require special treatment, unless they face long and frequent crises.

Supraventricular tachycardia is the most common form of arrhythmia and observed over time in women and children.

Tachycardia paroxysmal tachycardia can be classified by the atrio-ventricular node reentry and atrioventricular reentrant.

Paroxysmal tachycardia occurs with a sudden acceleration in heart rate; heart begins to beat very rapidly between 120-250 beats per minute. Paroxysmal tachycardia crisis may take minutes or hours, and so suddenly to return to normal heart rate.

After such attacks the patient feels worn out, with a feeling of not keeping up, blood pressure will drop suddenly and the patient can unbalance and faint.

Treatment of acute crisis calls that trigger reflex vagal maneuvers and intravenous injection. Further, it can be prescribed a preventive antiarrhythmic treatment.

The main symptom is palpitations tachycardia, or feeling that the heart beats too fast. The tachycardia is more serious, the symptoms are more severe:

Feeling empty head, dizziness or fainting;

Shortness of breath;

Tiredness;

Severe anxiety;

Cold sweat;

Nausea.

The best prevention method is to adopt a heart healthy lifestyle. This means:

Maintaining an optimal weight;

Eating healthy;

Physical activity regularly, but not exaggerated;

Quitting smoking, alcohol, spices;

Avoid stimulants, such as caffeine;
