Anxiety around Heart. Way forward. thx.

Hello Doc, I'm on sugar & cholesterol medication since last 4-5 years. (Voage 10 & Lipvas 20) Few days back i had little uncomfortness near my heart area. Yesterday morning at 11 am i was doing yoga & my pulse dropped to 30-40 for 30-40 secs and i was feeling light headed and full of anxiety (ghabrahat). I check my bp which was 120 by 81. I consumed lemon water with black salt and felt much better I went to see Doc where he checked my pulse and it was fluctuating a little on higher side (90-110) he called me again in the evening to check again. In evening pulse was 110 but not fluctuating. At home pulse was between 60-100. Doc gave me a pill to control my pulse and suggested to go have fun and not think much. But today too there is still some ghabrahat around heart. No pain in left arm or chest. Just some uneasiness. Got a blood test done today attaching full report. Platelets are less. Rdw,pdw,mpv are more. Albumin is little higher. Rest all ok. Kindly suggest the way forward. Thx.
