Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: transient ekg changes?I am a 24F, 5'3, 160 pounds. Location on body: heart duration of complaint: since December 8th, 2022. Symptoms, nearly fainting randomly, sharp chest pains that come and go, lightheadedness that gets worse at times, also knuckles, knees, and hands go pale or purple randomly. Concerned about poor circulation. Meds: none, medical problems: sjogrens syndrome, mild anemia, rheumatology suspects dysautonomia, asthma, sleep apnea (use CPAP), The ER did an EKG last night and in the notes it said the t wave depression was consistent with incomplete right bundle branch block. Yet I went to urgent care today for the same chest discomfort, lightheadedness and near fainting episodes (with seeing colors) (didn't want to go to the ER again) and they showed a normal EKG. Can these changes be trainsient and induced by stress, or lack of sleep? I am also concerned my body is shutting down because my body temperature is lower then it usually is. It's usually 98.5 but it's been between 95-97F these past few days let it can't regulate itsself.. ### Response: They can be transient. They can also be due to improper lead placement.
