Well let me start off by saying im a 29 year old woman, overweight and not fit. I have been working on losing weight lately but its happening slowly. All of my life I've had tachycardia. Meaning my resting heart rate stays on the high end... between 85-100. I also have panic disorder and during panic attacks it can go up to 150? or more. Anyways, i had a heart check up a few years back to check on this and everything was clear but I havent been able to go back as I can no longer afford insurance. A couple days ago I noticed I've been feeling foggy headed maybe slightly dizzy so I took my HR. Since then I've been monitoring and it's been as low as 60 resting and even panicking only around 85. I KNOW these are normal ranges for anyone else. But given how I've always had tachycardia and monitored that off and on, I'm pretty scared that mine has suddenly went low out of the blue. It's not normal for me... I tried looking online to see if I should be concerned but most articles focus on suddenly increasing HR, not decreasing. I'm not sure what to think. Any insight or similar experience?
