Thank you for asking on Chat Doctor! I understand your concern, and would explain that your symptoms may be related to a cardiac arrhythmia. Based on your cardio vascular risk factors hypertension, psoriasis and diabetes, a cardiac check up is necessary. I recommend consulting with your attending physician for a careful physical examination, a resting ECG, a chest x-ray and some blood lab tests : - complete blood count-fasting glucose and HbA1C- PCR, sedimentation rate-kidney and liver function tests-blood electrolytes- thyroid hormone levels, etc. An ambulatory 24 -48 hour ECG monitoring and a cardiac ultrasound are necessary to rule inout a possible cardiac arrhythmia. Hope to have been helpful! Best regards,
