Each one feels reasonable in the moment.</p><p><strong>Assuming the worst.</strong> Anxiety is the most common cause of palpitations, and panicking about a flutter feeds the same loop that caused it. Slow breathing, meditation or yoga calms the anxious kind.</p><p><strong>Ignoring them entirely.</strong> The opposite mistake. Brief and rare needs nothing, but frequent, worsening or all-day palpitations deserve a check, because silent AFib is real.</p><p><strong>Stacking stimulants anyway.</strong> Energy drinks, decongestants, nicotine and some supplements pile onto the same racing heart. Cutting the stack is often the whole treatment.</p><div class="acv-plan ac-plan" id="coach-recommendations"><div class="acv-ptitle"><span class="acv-ico">📋</span>Your Coach's Recommendations</div><div class="step"><div class="acv-n">1</div><div><div class="sh">Log the pattern for one week.</div><div class="sd">Write down when palpitations start and stop, what you were doing, and how the beat felt.

They are common, usually brief, and most often triggered by stress, stimulants or exercise. They matter when they come with chest pain, fainting, severe breathlessness or severe dizziness, or when they become frequent and worsening. Those earn medical care.</div></details><details><summary>Why does my heart flutter at night?</summary><div class="acv-a">Night palpitations are usually the same as daytime ones. You notice them more because you are lying quietly with no distractions. Sleeping on your side can also increase pressure in a way some people feel. Log them and mention them at your next visit.</div></details><details><summary>Can anxiety really cause palpitations?</summary><div class="acv-a">Yes, and it is the most common cause. Stress hormones speed the heart and make every beat easier to feel. Calming practices like slow breathing, meditation and yoga reduce them. If anxiety and palpitations keep pairing up, tell your doctor.</div></details><details><summary>How much coffee is too much for my heart?</summary><div class="acv-a">There is no single number. Caffeine is a stimulant, and it is a common palpitation trigger, so the practical test is your own pattern. If flutters follow your coffee, energy drink or pre-workout, cutting back is the first fix to try.</div></details><details><summary>What tests will the doctor run for palpitations?</summary><div class="acv-a">Usually simple ones. Expect a listen with the stethoscope, blood tests, and often an electrocardiogram. If nothing shows up in the office, a Holter monitor or another wearable records your rhythm over a day or longer to catch the moment.</div></details><details><summary>What happens if it turns out to be AFib?</summary><div class="acv-a">AFib is treatable. Options include medicines that control the rhythm or rate, procedures, and treating the conditions that feed it. Managing it matters because untreated AFib raises stroke risk about fivefold, which is why finding it early is a win.</div></details></div><div class="acv-secondary">Wondering where you stand overall? <a href="/#assessment">Take the free 5-minute Healthspan Snapshot</a> and see your strongest and weakest of six dimensions.</div></div>
