Irregular heartbeat in a 16-year-old child may be caused by physiological factors, such as physiological sinus arrhythmia, etc. It may also be caused by pathological factors, such as premature beats and atrial fibrillation.
1. Physiological sinus arrhythmia: heart rate is affected by autonomic nerves (including sympathetic and vagus nerves), sympathetic nerve excitation can make the heart rate faster, vagus nerve excitation can make the heart rate slower, the autonomic function of teenagers is unstable, which can easily cause sinus arrhythmia, and thus irregular heartbeat occurs. For example, adolescents often have a heart rate that accelerates with inhalation and slows down with exhalation.
2. Premature beats: including atrial premature beats, ventricular premature beats, etc. It refers to the premature contraction of the heart due to the premature impulse from an ectopic pacing point, which can lead to irregular heartbeats.
3. Atrial fibrillation: atrial fibrillation can also occur in teenagers, and when it occurs, it manifests itself in the form of varying heart tones and absolute arrhythmia, which can lead to irregular heartbeats.
If a 16-year-old child has frequent irregular heartbeats, it is best to go to a regular hospital in time to improve the relevant examinations, standardized treatment under the guidance of a professional doctor to avoid delays in the condition.
