Upright: A Cardiologist's Guide to Living with POTS and Other Dysautonomias

Your tests are normal. You are not imagining this.

Millions of people are told their racing heart, dizziness, brain fog, and bone-deep fatigue are just anxiety. They are not. They have dysautonomia, a disorder of the body's automatic controls, and it can be understood, explained, and managed.

In Upright , cardiac electrophysiologist Dr. Peem Lorvidhaya hands you the exact framework he uses in clinic. No vague reassurance, no dismissive shrug. Just a clear explanation of what is happening inside your body and a practical plan to get your life back.

Inside, you'll learn:

What POTS, vasovagal syncope, inappropriate sinus tachycardia, and orthostatic hypotension actually are, and why they happen
The small, practical levers that restore function: salt, fluids, compression, conditioning, and carefully matched medication
How to recognize the conditions that often travel with dysautonomia, including hypermobility and hEDS, MCAS, and long COVID
How to pace, recondition, and avoid the push-crash cycle
How to navigate work, school, pregnancy, and finding a doctor who actually listens

Mechanism-first, deeply practical, and genuinely human, Upright turns everything looks fine into a plan you can actually follow.

For patients, caregivers, and the clinicians who care for them.
