My husband has been in 3 different hositals in 3 dif states coming back from our vacation . He is 75, a heart patient (quadruple bypass), cancer survivor of 8 yrs, diabetic. He started getting dizzy spells, angina, headaches that turned to loss of vision. He passed out completely the mid of April, hospitalized and released saying same as all others, it is not his heart. Last two episodes he has been hollering out loud like he is in a nightmare. I am afraid he is having strokes. What do you think. He has had head scan and EEG, chest scan, stress test, MRI, Check of carotid artery, dye test for other possible clots, each time all negative
Please be careful travelling with these conditions may be too much and may be resulting in fatigue. With these conditions he may be taking a few meds which may cause postural hypotension and dizziness. Also he may be having arrhythmiaswhich should be checked by long term monitor. Make sure he is optimally HY Chat Doctor.  Also try to check for low sugar. Except some pain pericarditis does not cause any dizziness. But if it does then it is very serious and should be checked with echocardiogram
