Will be making a doctors appointment on Monday, quite worried and wondering if anyone else has experiences of this. I'm 29 years old two children and fairly active. I often get tight chested and heart palpitations. My blood pressure is always fine however my pulse is never below 100 even when resting. After doing housework it can be at least 129 and often higher. I don't drink alcohol but I do vape. Often feel lightheaded too. Can this just be normal and the way I am ? Looking for people's experience.
