<s>[INST] Hello doctor,The patient suddenly feels chills all over the body after taking a beta blocker, calcium channel blocker, Clopidogrel, Aspirin, and Atorvastatin. She is unable to stand, walk or move. The BP monitor shows e3/e4 error, not showing any BP value. When checked in sphygmomanometer there is Korotkoff sound at any point (no pulse). Also, the patient feels severe vomiting. What is the problem? Is it a shock or heart failure or cardiac arrhythmia or heart attack? [/INST] Hello. I have reviewed your query and can understand you are worried about a patient who is feeling a bunch of symptoms. Thanks for adding the detailed medications she is taking. From her overall scenario, based on the information provided, it seems she may be having issues due to medication dosage. There is a possibility that, as she takes the medications like calcium channel blocker and a beta blocker, her blood pressure falls to the extent that she feels pulseless, chills all over the body, vomiting, and weakness. You need to consult her treating physician in order to go for some tests like thyroid function test, EKG and/or others he feels appropriate. Also, discuss with him if there is a need for change in medications or dosage of medications. Adjustment of dose usually suffices. Hope it helps. Please feel free to ask more if you need further assistance. I would be happy to help. For more information consult a cardiologist online --> </s>
