I did an ecg about six months ago and everything was fine. yesterday i suddenly felt like fainting, increased heart rate, low pressure when i was sat. should i do another ecg? or should my heart be fine cause its only been 6 months?

Ecg : You should establish with a cardiologist that based on reviewing all medical details would be able to set up a plan. An ecg only reflects heart changes at the time is done and has no predictive ability. You need a test that will be able to register your heart activity at the time you have your symptoms and there are now heart monitors that can do that.
