Family history is of much importance regarding heart disease
as they usually run in families but the description you have provided seems to be less likely of heart problem. It seems to be more likely due to nerve

The second cause can be depressive illness which causes neurotransmitter
imbalance and subsequently causing these sensations.
complex is effective in such conditions and also the correction of cause is important.
