It's got a lot worse though the last few months, I used tom just get heart palpitations every now and then and chest pains sometimes. Now I get weird heartbeats etc 
Last few months I am not surprised. Same as me, I have been having panic attacks lately.
As to the weird heartbeats (arrhythmia?), it could be low potasium. My mum had low potassium levels and her heart started beating irregularly. It is something to do with the electricals in the heart. Anyway, now she takes potassium pills and is fine. 
So yes, off to the doctor with you. I bet you haven't told your mum about this yet either. 
When I was in my thirties, I was trying to find out what was different about/wrong with me (mainly due to influence from my live-in girlfriend at the time) and went for many tests. I was diagnosed with food allergies. Along with their treatments they discovered that certain minerals and elements in my system were totally out of whack, with impossible concentrations of some and impossible shortages of others, including potassium.
It took a while, but I eventually saw it as a wake-up call to be more aware of what I put into my system. I have not always kept up good habits, but I try to.
It could be something this easy to fix, without adding even more meds to your system.
