Hello I'm a 34 yr old male, I have been having lightheaded, nausea, atypical chest pains lately. One thing I have noticed is that any sort of emotions like laughing, will tend to make things worse or bring on an episode of palpitations..... or the symptoms also get worse and better on their own...... What does this tell you? Emotions in particular laughing or other excitement really make me feel weak in the heart and cause palpitations, what does this tell you?
