Rapid heart beat and pounding

Ok guys im still having this, ive tried mag, calcium, replacing pottasium.

The only thing thats helping slightly is mulungu a really good herb guys for regulating heart rate and helping liver and spleen etc

Anyway even though ive had an ECG, i did hard drugs, still smoke fags which im quitting this week, my veins are all sore blue and raised. Im fatigued all the time. Im short of breathe all the time

Ive really scared myself into thinking its heart disease and have been in a major downer:(.
