I read your question carefully and I understand your concern.

Judging from your description the drop in blood pressure occurred after vomiting. In that case if you have no other issue which might indicate a heart issue (such as chest pain, abnormal heart beats) then perhaps the drop of the blood pressure was simply due to vomiting. Loss of water and electrolytes may lead to a drop in blood pressure. Afterwards your cardiovascular system reacted by adapting the work of the heart and the tension in your blood vessels in order to bring blood pressure back to 110/58 which is close to your normal values. So for the moment I would advise only to stay hydrated.

I hope to have been of help.
