Palpitations, chest tightness, what's going on?

Palpitations and chest tightness may be related to psychological factors, environmental factors or disease factors.

1. Psychological factors

When emotions are too excited, angry or anxious, due to sympathetic nerve excitation, the body's oxygen consumption increases, which may cause palpitations and chest tightness.

2. Environmental factors

If you are in a crowded and chaotic environment or the surrounding environment is relatively hot, due to insufficient ventilation, the body may lack oxygen, and palpitations and chest tightness may also occur.

3. Disease factors

Coronary heart disease, angina pectoris, arrhythmia, heart failure and other heart diseases as well as autonomic nerve disorders, emphysema, chronic obstructive pulmonary disease, etc. can cause palpitations and chest tightness.
