“I have had patients whose palpitations turned out to be panic, and others whose anxiety was actually atrial fibrillation or a blocked artery. Try breathing in for four, holding for seven, and exhaling for eight; if your heart rate does not slow, call your doctor and get checked.”

“I once listened to my own heart during a med-school exercise, heard three beats, and spiraled into sheer terror as my chest went bam-bam-bam so hard the clinic couldn't get a clean EKG. That's why I always tell people: get the cardiac workup first to rule out anything physical, then we can treat what your nervous system is doing with that information.”

“I spent twenty-five years as a cardiologist, and the honest answer is: you cannot tell from the feeling alone. Anxiety can raise your heart rate and mimic cardiac symptoms, but so can arrhythmias, ischemia, and other cardiac problems, so I would get checked before assuming it is just stress.”

“I’ve had patients sit across from me swearing it was anxiety, and the ECG showed atrial fibrillation; others were sure it was their heart, and it was panic. The two feel nearly identical, so I tell people to get checked once, properly, and then you can call the rest anxiety with confidence.”

“If your heart is racing with chest pressure, fainting, or it started during exertion, treat it as cardiac first and get checked now. Anxiety is real and common, but I have seen too many people dismissed as anxious when the rhythm or plaque was the actual problem.”

“I hear that racing heart, and I want to be straight with you: I can't tell you from here whether it's anxiety or a cardiac issue, and neither can a screen. If this is new, severe, or you have chest pain, dizziness, or shortness of breath, please call your doctor or go to urgent care to rule out anything physical first.”

“I had a clean bill of health one month before my massive heart attack in 2009, and I learned that anxiety, fatigue, or a racing heart can be subtle warnings, not just stress. If your heart is racing and something feels off, get checked now, because waiting to be sure is the gamble I almost didn't survive.”

“I tell my patients to trust their gut: if something feels wrong, call 911 and let the emergency team sort out whether it is anxiety, an arrhythmia, or your heart. Time is heart, and I'd rather you be evaluated and told it is panic than wait and have it be something else.”

“I can't tell you which it is from here, but I can tell you that palpitations are one of the symptoms I take seriously enough to evaluate. In my practice, we use a monitor to catch the rhythm when it's actually happening, because anxiety and arrhythmia can feel identical and the stakes of missing a real rhythm problem are too high.”
