Extrasystoles: Or something else? Differential Diagnosis

Cardiovascular System (I00-I99).

  • Atrioventricular re-entrant tachycardia (AVRT) – belongs to paroxysmal supraventricular tachycardia; results in seizure-like episodes of tachycardia (heartbeat too fast: >100 beats per minute), dizziness, and possibly signs of acute heart failure (heart weakness
  • Sinus arrhythmia – usually respiratory sinus arrhythmia (physiological fluctuation of the heart rate, due to respiration).
  • Sinus tachycardia – increased heart rate of more than 100 beats per minute, originating from the sinus node.
  • Ventricular tachycardiacardiac arrhythmia with too fast heartbeat, originating from the ventricles.
  • Atrial flutter – cardiac arrhythmia in which the atria of the heart beat irregularly 240 to 340 times per minute at rest, while the ventricles usually beat more slowly
  • Atrial fibrillationcardiac arrhythmia with subordinate activity of the atria.
