Paroxysmal cardiac rhythm

Paroxysmal tachycardia or tachyarrhythmia is a disease of the cardiovascular system, causing unexpectedly manifested by changes in heart rhythm or to 250 beats per minute. Tachycardia is the most common form of arrhythmia and requires urgent treatment, because a very high risk of development of acute circulatory failure.

Paroxysmal disorders can manifest in any part of the heart. The following types of tachyarrhythmias, depending on the zone of influence:

Atrial tachyarrhythmia or supraventricular. Reasons are neurosis, caused the defeat of the Central nervous system, and various heart disease ( insufficiency of the tricuspid valve, mitral stenosis, etc), heart surgery.

Ventricular tachyarrhythmia that main cause are organic lesions of the heart (cardiomyopathy, myocarditis). It can also occur due to an overdose of the drug digitalis, a heart operations. In more rare cases can develop when strong psychophysical fatigue and vegetative-vascular dystonia.

Symptoms of paroxysmal tachyarrhythmias due to the duration of the attack, the place of exposure and disease, caused tachycardia. The disease appears suddenly in the form of unpleasant sensations in the heart area (interruptions, fading).

When atrial tachyarrhythmias appears shivering, sweating, frequent urination, diarrhea. When listening to the heart (auscultation) distinguishable pleased with frequent loud rhythmic tones.

When ventricular tachyarrhythmias experience fear, anxiety, dizziness, fainting. When listening to a stethoscope can hear the weakened heart sounds, the arrhythmia.

Treatment of paroxysmal cardiac arrhythmia carried out in the following ways:

1. Welcome antiaritmicski drugs (often used amiodarone)

2. Electrophysiologically therapy:

The cardioversion (defibrillation) - treatment is carried out using a powerful electric pulse. Conducted in the presence of fibrillation for more than 48 hours.

Elektrocardiostimulyatsia - this method is based on creating the heart of the beat using a pulsed electric current.

Catheter ablation - treatment is carried out using a specially flexible tube (katatura), which is supplied to the heart through an incision in the skin through the blood vessel. Through a tube held radio frequency, which can offset the cells, causing the tachycardia.
