Reposting from general health. DD2 (young adult) has had an ECG after she mentioned to the practice nurse during an appointment she gets occasional palpitations and tachycardia. She has ASD so she/we always put it down to anxiety and the stress of masking.
The ECG showed QRS depression and a prolonged QT segment. The GP has requested bloods and 24hour monitoring before another appointment. What can causes this? Do I need to be as worried as google has made me?
