Cardiovascular System (I00-I99).
- Atrioventricular re-entrant tachycardia through an accessory pathway (AVRT) – supraventricular arrhythmia resulting in a circular excitation between the atrium and ventricle through an accessory pathway.
- Adenosine-sensitive ectopic atrial tachycardia.
- Sinus tachycardia (heartbeat too fast: > 100 beats per minute).
- Ventricular tachycardia – cardiac 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 fibrillation – cardiac arrhythmia with subordinate activity of the atria.
Psyche – nervous system (F00-F99; G00-G99)
- Anxiety neurosis*
- Psychogenic hyperventilation (increased breathing beyond what is required)* .
* Frequent misdiagnosis.
