![]() “If heart palpitations happen every time you do, like walk half a mile or lift something, that’s not a random event and you should be evaluated,” Dr. ![]() That said, experiencing them regularly is not. One-off heart palpitations that just last a few seconds are a normal part of having a heart. You may be wondering when to worry about heart palpitations, especially when most of the time, they’re NBD. All told, here’s when you should go see your doctor. You may also experience heart palpitations if you have a physical abnormality like a weaker or larger heart than usual, which you typically wouldn’t know about unless it showed up during some kind of medical exam. This can lead to a rapid or irregular heartbeat, along with symptoms like an increased appetite and sudden weight loss. If your thyroid is on overdrive (aka, you have hyperthyroidism), it will generate too much thyroxine, which kicks up your body’s metabolism. Your thyroid produces hormones like thyroxine and triiodothyronine, which influence many of your body’s systems, according to the Mayo Clinic. Other times, heart palpitations can be a sign that something’s up with a different organ, like your thyroid gland. If you think you’re experiencing any strange symptoms along with your heart palpitations, seek medical attention immediately. Only a doctor can tell you for sure, but any symptoms besides the strange heart sensations are typically a clue that your arrhythmia may be more serious, says the NHLBI.

You may or may not develop other symptoms at the same time. That’s why experiencing palpitations during or after a tough workout isn’t immediately a reason to worry. Heart palpitations are heartbeats that can become noticeable. Things that make your heart work harder can also cause palpitations, Dr. Your heart has receptors that pick up on heightened adrenaline, so any surges of this hormone can cause it to act differently. That includes stress, panic attacks, caffeine, having a cold or flu, being sleep-deprived, and taking medications that contain stimulants. If your SA node starts sending wonky electrical impulses, you might experience heart palpitations.Īnything that increases the adrenaline in your body can affect these electrical impulses, Dr. ![]() These cells are housed in your heart’s right chamber, also known as its right atrium. Typically, your heart knows when to squeeze based on electrical impulses from a group of cells known as your sinoatrial (SA) node, according to the National Heart, Lung, and Blood Institute (NHLBI). ![]()
