Hello and welcome to HCM.
Thanks for putting your query over here.
Chest tightness along with palpitations can have some specific causes and it demands doing certain investigations to know the cause before any medications are started.
If I were your treating doctor,I recommend-
-Blood pressure measurement,advice ECG,stress tests,serum thyroid tests,blood glucose,blood lipids
- Certain medications like
metoprolol are started for controlling
heart rate -Control stress and anxiety by yoga,
meditation,mind
relaxation techniques,listening to soothing music,engaging in some hobby.
-Balanced diet,avoiding exposure to second hand and primary smoke,avoiding excess intake of caffeine.
-Keep weight within control by regular exercising(after ruling out certain heart conditions)
Thanks and regards.
