I am a 45y/o WM who resumed working out today (x1 hr, resistance & 35min cardio) after hiatus since 2/13. I finished my workout 1hr ago and after running some errands returned home to rest. I have been seated on my couch since that time. I have slight nauseous and, according to my wrist-worn cardiometer, my pulse rate has stayed around 102-106.I have no angina, dizziness, sweatiness or SOB. I do have a Hx of CAD (1 reason for the cardiometer)w/last MI being in 2010. Please advise.
