Sudden palpitations. What's going on?

Sudden palpitations are considered to be caused by emotional excitement, drinking strong tea, coffee or arrhythmia.

1. Emotional excitement

can lead to increased sympathetic excitability, releasing excitatory neurotransmitters. When these neurotransmitters act on the heart, they will cause palpitations.

2. Drinking strong tea, coffee, strong tea

contains tea polyphenols, coffee contains caffeine, both of which are substances that are easy to cause excitement. A large intake may cause mental excitement, resulting in palpitations.

3. Arrhythmia

may lead to insufficient blood supply to the heart, resulting in compensatory acceleration of heart rate, resulting in palpitations.
