Cardiovascular System (I00-I99).
- Atrioventricular re-entrant tachycardia (AVRT) – belongs to the paroxysmal supraventricular tachycardias and leads to typical seizure-like episodes with tachycardia (heartbeat too fast: > 100 beats per minute), dizziness, and possibly signs of acute heart failure (cardiac insufficiency)
- Extrasystoles (heart stutter) – heartbeat that occurs outside the physiological heart rhythm.
- Kammerflatternv – life-threatening cardiac arrhythmia with rapid succession of relatively irregular ventricular action with a heart rate of 200 to 350/min; the transition to ventricular fibrillation is fluid.
- Ventricular fibrillation – life-threatening pulseless cardiac arrhythmia in which disordered excitations occur in the ventricles and the heart muscle no longer contracts in an orderly fashion
- Atrial fibrillation – cardiac arrhythmia with subordinate cardiac activity of the atria.
- Sinus tachycardia – increased heart rate increased 100 beats per minute, originating from the sinus node.
- Ventricular tachycardia – cardiac arrhythmia with too fast heartbeat, originating from the ventricle.
