<s>[INST] My son Joshua is 35 years old. He has hydrocephalus. He has a shunt that has been checked out at University hospital with no presure problems. Joshua has developed a problem with his pulse dropping to 40 beats per minuite and his blood preasure getting as high as 160 over 110. We took him to a Dr of Neurology and she put him on blood preasure medicine and Topiramate. After a week on blood preasure med he started to pass out. I took him off, and to hospital. MRI,CT,EEG,EKG,and ultrsound of heart look good. We left with no answers and my son still has terrible headaches. 5-6 a day... any suggestions...Jack Slaasted [/INST] Hi, Increased intracranial pressure can cause a variety of ECG disturbances ranging from low to the high heartbeat and abnormal arrhythmia. Echo in these cases will be absolutely normal. The treatment is just to lower the intracranial pressure. So there is nothing cardiologist will do about it, and you should see your neurologist again. Hope I have answered your query. Let me know if I can assist you further.  </s>
