[|Human|] I am on a telephone call with a friend traveling in India.  She has just reported waking about 45 minutes ago with palpitations, lightheadedness, and frequent urnination.  She measures her pulse at 130 and perhaps accelerating.  Noting notably abnormal about her diet today; dinner included shrimp.  She had a glass of wine with dinner and is taking the oral anti-malarial drug, but has had no effects from same over the past two weeks.
[|AI|]  Hi, Increased heart rate & palpitations can be because of a lot of causes. It can be normal sinus tachycardia due to anxiety or stress, or it could be abnormal supra ventricular tachycardia. Malaria medication can also cause it to increase. For the diagnosis, you need to do ECG at the time of palpitation & tachycardia. If the duration of palpitations are short enough to reach a nearby hospital, we put a 24hr ECG monitoring (Holder Monitor). You also need to do a 2D Echo & thyroid function test to see for any associated abnormality if any
