Duration is not the factor here.<\/p>\n<p>Rather, frequency plus other accompanying signs decide if the heart palpitations in question are a reason to be concerned. The American Heart Association points out that palpitations lasting minutes up to hours definitely are a call for action, particularly when new symptoms appear alongside them.<\/p>\n<h3><strong>Palpitations That Keep Becoming More Frequent<\/strong><\/h3>\n<p>A change in the pattern of palpitation occurrences may be a useful indicator of a problem rather than being a one-off incident.<\/p>\n<p>If for instance, your old occasional palpitations are turning weekly now or you mostly get heart palpitations when lying down at night, or they are getting more intense every time, this departure from your normal baseline should not be ignored but rather be brought to the attention of a cardiologist.<\/p>\n<p>There are different kinds of situations when your heartbeat seems abnormal. Recognizing these variations is just an initial step but is not the end.<\/p>\n<p>It&#8217;s just as important to understand what a normal test result does and doesn&#8217;t rule out.<\/p>\n<p><a href=\"https:\/\/bigapollospectra.com\/service\/cardiology\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-752 size-full\" src=\"https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2025\/03\/cardiologist-in-patna.webp\" alt=\"cardiologist in patna\" width=\"800\" height=\"200\" srcset=\"https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2025\/03\/cardiologist-in-patna.webp 800w, https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2025\/03\/cardiologist-in-patna-300x75.webp 300w, https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2025\/03\/cardiologist-in-patna-768x192.webp 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Heart_Palpitations_but_Normal_ECG\"><\/span><strong>Heart Palpitations but Normal ECG<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A regular ECG obtained during your check-up may not necessarily indicate that nothing is wrong with the patient&#8217;s heart.<\/p>\n<p>Because of the intermittent nature of arrhythmias, a standard ECG lasting only for a few seconds of time could miss an episode.<\/p>\n<p>If your palpitations are so regular that you are being referred for investigation and your resting ECG is still normal, your cardiologist may suggest doing heart-rhythm monitoring for a longer time period as a way of capturing your abnormal rhythms.<\/p>\n<p>While a single normal ECG gives one relief, one should not be misled if this is the only conclusion and your symptoms don&#8217;t disappear.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Do_Heart_Palpitations_Feel_Like\"><\/span><strong>What Do Heart Palpitations Feel Like?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1644 aligncenter\" src=\"https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2026\/08\/Heart-Palpitation.webp\" alt=\"Heart Palpitation\" width=\"900\" height=\"500\" srcset=\"https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2026\/08\/Heart-Palpitation.webp 900w, https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2026\/08\/Heart-Palpitation-300x167.webp 300w, https:\/\/bigapollospectra.com\/blog\/wp-content\/uploads\/2026\/08\/Heart-Palpitation-768x427.webp 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>Heart palpitation is very well captured by one&#8217;s perception, which, from one person to another, is very much the same.<\/p>\n<p>The feeling one is aware of is a racing heart, a heavy pound, light fluttery sensations, or just a skipped beat or an extra beat.

So, in layman terms, arrhythmia is just irregular heartbeats.<\/p>\n<p>However, if these signals are delayed, premature, or out of sequence, your heart may feel as though fluttering, pounding, or skipping a beat.<\/p>\n<p>Atrial fibrillation is an example of a common type of arrhythmia that may cause palpitations, but the reality is palpitations can be caused by a myriad of other things besides that.<\/p>\n<p>Moreover, just having an episode of palpitations should not be considered strong enough evidence for someone to be diagnosed with AFib or another type of arrhythmia.<\/p>\n<p>If you are curious about how anxiety is able to produce symptoms similar to this condition, our blog on <span style=\"text-decoration: underline;\"><a href=\"https:\/\/bigapollospectra.com\/blog\/can-anxiety-cause-atrial-fibrillation-symptoms\/\" target=\"_blank\" rel=\"noopener\">anxiety and atrial fibrillation symptoms<\/a><\/span> talks in further detail about these similarities.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Can_You_Do_When_Heart_Palpitations_Occur\"><\/span><strong>What Can You Do When Heart Palpitations Occur?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you start having a palpitation, a few simple steps may be taken so you can handle it safely.<\/p>\n<p>Cease intense exercise when symptoms appear during workout &#8211; sit down and try to remain calm.<\/p>\n<p><strong>Then, if possible:<\/strong><\/p>\n<ul>\n<li aria-level=\"1\">Record when the palpitation started and its duration<\/li>\n<li aria-level=\"1\">Note your activity just before the event<\/li>\n<li aria-level=\"1\">Keep track of caffeine intake, medication use, level of stress, amount of sleep, and dehydration<\/li>\n<li aria-level=\"1\">Go to emergency department for care right away if signs are of the life-threatening nature<\/li>\n<\/ul>\n<p>Keeping a symptoms journal to track patterns over time can allow you to prepare better information for the cardiology consult.<\/p>\n<p>However, if you are searching for a way to stop heart palpitations due to anxiety immediately, taking deep breaths at a slower pace tends to ease the sensation but should not be taken as a means of diagnosis or treatment in case recurring episodes continue to happen.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span><strong>Frequently Asked Questions<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Following are some of the common queries answered regarding heart palpitations, their complications, and the available diagnostic methods.<\/p>\n<h3><strong>1. When should I get worried about heart palpitations?\u00a0<\/strong><\/h3>\n<p>Worry when they come with chest pain, breathlessness, dizziness, or fainting, or when they&#8217;re new and worsening.<\/p>\n<h3><strong>2. What are 5 signs your heart is in danger?<\/strong><\/h3>\n<p>Chest pain, severe breathlessness, fainting, cold sweats, and prolonged palpitations together suggest urgent evaluation is needed.<\/p>\n<h3><strong>3. How long is it bad for heart palpitations?<\/strong><\/h3>\n<p>There&#8217;s no fixed cutoff, but episodes lasting minutes to hours, especially with other symptoms, should be evaluated promptly.<\/p>\n<h3><strong>4. Are heart palpitations dangerous?\u00a0<\/strong><\/h3>\n<p>Most are harmless and trigger-related, but palpitations with chest pain, dizziness, or fainting can signal a serious condition.<\/p>\n<h3><strong>5. What do dangerous heart palpitations feel like?\u00a0<\/strong><\/h3>\n<p>They often feel intense or prolonged, occurring alongside chest pressure, breathlessness, dizziness, or faintness.<\/p>\n<h3><strong>6. Can anxiety cause heart palpitations?\u00a0<\/strong><\/h3>\n<p>Yes, anxiety is one of the most common triggers, usually through increased adrenaline and a faster heart rate.<\/p>\n<h3><strong>7. Can heart palpitations be a sign of a heart attack?\u00a0<\/strong><\/h3>\n<p>Yes, especially with chest pain, pressure, sweating, or shortness of breath, which needs emergency evaluation.<\/p>\n<h3><strong>8. Can heart palpitations be a sign of atrial fibrillation?\u00a0<\/strong><\/h3>\n<p>Yes, AFib can cause palpitations, though symptoms alone can&#8217;t confirm it. An ECG or rhythm monitor is needed.<\/p>\n<h3><strong>9. What tests are done for frequent heart palpitations?\u00a0<\/strong><\/h3>\n<p>Common tests include an ECG, Holter monitoring, echocardiography, and blood tests for thyroid (<span style=\"text-decoration: underline;\"><a href=\"https:\/\/bigapollospectra.com\/blog\/how-is-thyroid-related-to-heart-problems\/\" target=\"_blank\" rel=\"noopener\">heart disease and thyroid connection<\/a><\/span>), or electrolyte issues.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Take_Your_Heart_Palpitations_Seriously_Without_Panicking\"><\/span><strong>Take Your Heart Palpitations Seriously, Without Panicking<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It is common for occasional palpitations to affect individuals but are generally nothing to worry about.
