I have a bad cold that just came on and I can't stop coughing.The part I'm worried about being affected by this is the tilt table.My appt. is this Tuesday,the next available is June 29,so that's not long considering I've waited 3 months for the June 15 slot.I want this test to be very accurate of course and don't want my heart rate and bp to be elevated from me hacking up a lung on the table.What do you think?
