Sinus tachycardia.jpg

Sinus tachycardia is a form of supraventricular tachyarrhythmia, characterized by an accelerated sinus rhythm (i.e., the rhythm of the sinus node) with a heart rate of more than 90 beats per minute in adults.

Clinical value has a sinus tachycardia, which remains at rest. Often it is accompanied by unpleasant sensations of "palpitation", a feeling of lack of air, although some patients may not notice an increase in heart rate. The causes of such a tachycardia can be both extracardiac factors, and actually heart disease.

Sinus tachycardia is characterized by:

  1. increase in heart rate more than 90 beats per minute;
  2. maintaining the right sinus rhythm;
  3. positive P wave in leads I, II, aVF, V4-V6;
  4. with a pronounced sinus tachycardia, the PQ (R) interval is shortened (but not less than 0.12 s) and the duration of the QT interval is decreased, the amplitude of P wave in the leads I, II, aVF is increased, the amplitude of the T wave is increased or decreased, the upslopping ST segment depression(not more than 1.0 mm below the isoline).

This pathology can be detected using ECG Dongle [1], ECG Dongle Full [2] and «Serdechko» [3].
