Lately, Ive been noticing that every time I stand up or go for a walk, my heart starts racing to around 130bpm, and it doesnt calm down until I sit or lie down. My chest hurts, and my legs feel weak and shaky during these times too. I did have an iron deficiency last year, but it never made me feel like this, and even though it's still slightly low, my recent results show it's getting better. Ive had an ECG done, and that seemed fine, so I'm wondering if I should be seeing a cardiologist. Could this be something serious?
Yes, given your symptoms of a racing heart rate when standing or walking, chest pain, and weakness in your legs, it would be prudent to visit a cardiologist. These symptoms may indicate a condition called postural orthostatic tachycardia syndrome (POTS) or other cardiovascular issues that require further evaluation. Even though your ECG is fine and your iron levels are improving, it is essential to rule out any underlying heart conditions or dysautonomia. A cardiologist can perform additional tests, such as a Holter monitor, echocardiogram, or tilt table test, to better understand the cause of your symptoms and recommend an appropriate treatment plan.
