Heart palpitations feel like your heart is fluttering, pounding, racing, or skipping beats. The sensation can show up in your chest, but many people also feel it in their throat or neck. Most palpitations are brief and harmless, though the feeling can be unsettling, especially if you’ve never noticed it before.
How Palpitations Actually Feel
People describe palpitations in several distinct ways, and the sensation often depends on what your heart is actually doing at that moment. The most common descriptions fall into a few categories:
- Fluttering or quivering: A light, rapid trembling sensation in the chest, almost like a bird flapping its wings. This often corresponds to a brief run of fast heartbeats.
- Skipping or stopping: A sudden pause followed by a hard thump. Your heart didn’t actually stop. What happened is it fired an extra beat slightly early, then paused a fraction of a second longer before the next normal beat. That next beat is stronger than usual because the heart had a moment longer to fill with blood, producing the “thud” you feel.
- Pounding or thumping: A forceful heartbeat you can feel without putting your hand on your chest. Some people notice it while lying in bed at night when the body is otherwise still.
- Racing: A sustained fast heartbeat, sometimes over 100 beats per minute, that starts or stops abruptly. You may feel short of breath or lightheaded alongside it.
These sensations can last anywhere from a single beat to several minutes. Some people experience isolated episodes a few times a year, while others notice them daily for stretches of time.
Why You Feel Them in Your Throat
One of the more surprising aspects of palpitations is that they don’t always feel like they’re coming from your chest. Many people feel a fluttering or pulsing in the throat or neck. This happens because large blood vessels, particularly the jugular veins and carotid arteries, run close to the surface in your neck. When the heart contracts out of its normal rhythm or with extra force, you can feel that pulse wave ripple through those vessels. It doesn’t mean anything different from feeling it in your chest. It’s the same event, just sensed from a different location.
What Causes the Sensation
The “skipped beat” feeling usually comes from premature heartbeats. These are extra beats that originate from somewhere other than the heart’s normal pacemaker. Every heart has specialized tissue that fires electrical signals to keep the rhythm steady, but occasionally other cells in the heart fire on their own, slightly ahead of schedule. This creates a beat that arrives early, followed by a compensatory pause while the heart resets to its regular rhythm. You typically don’t feel the early beat itself. You feel the pause and the stronger-than-normal beat that follows.
Nearly everyone has these premature beats from time to time. They’re extremely common and, in most cases, completely benign.
Common Triggers
Palpitations don’t always have an obvious cause, but several things make them more likely. Caffeine is one of the most frequently reported triggers. Nicotine and stimulant drugs also increase the heart’s excitability. Strong emotions like anxiety, anger, or sudden surprise can set them off, as can physical exhaustion or poor sleep. Low levels of potassium, magnesium, or calcium in the blood can destabilize the heart’s electrical signaling and produce more frequent irregular beats.
Hormonal shifts are another major contributor. Thyroid hormones directly influence how fast and regularly the heart beats. An overactive thyroid can cause a fast, irregular heartbeat along with irritability, trouble sleeping, and difficulty tolerating heat. Pregnancy and menopause both involve significant hormonal changes that can trigger palpitations even in people who’ve never experienced them before.
How Common They Are
Palpitations are one of the most frequent complaints in outpatient medicine. In one study of ambulatory elderly adults, 8.3% reported experiencing palpitations. That number is likely higher across the general population when you include younger adults dealing with stress, caffeine consumption, and hormonal fluctuations. Notably, that same study found no correlation between reported palpitations and dangerous heart rhythms on resting heart tracings, reinforcing that the sensation itself is usually not a sign of something serious.
How Palpitations Are Evaluated
If you bring up palpitations with a doctor, the first step is a standard 12-lead electrocardiogram (EKG), which captures your heart’s electrical activity over about 10 seconds. This is appropriate for every patient who reports palpitations and can reveal rhythm abnormalities if one happens to occur during the recording.
The challenge is that palpitations are often intermittent. If yours happen daily, your doctor may have you wear a portable monitor for 24 to 48 hours that continuously records your heart’s activity. If your episodes are less predictable, a better option is a continuous-loop event recorder worn for about two weeks. This device constantly records but only saves data when you press a button during symptoms, capturing the few minutes before and after you felt something. That two-week window gives a much higher chance of catching what’s actually happening during an episode.
In many cases, the results are reassuring. The monitor confirms premature beats or a brief run of faster rhythm, both of which are typically harmless.
Stopping Palpitations in the Moment
For certain types of rapid palpitations, simple physical techniques called vagal maneuvers can help slow the heart by stimulating the vagus nerve. The most well-known is the Valsalva maneuver: you take a deep breath and bear down as if you’re trying to exhale forcefully through a blocked straw, holding for 10 to 30 seconds. Another approach involves submerging your face in ice-cold water or pressing a cold, wet towel against your face, which triggers a reflex that slows heart rate.
These techniques work best for a specific type of fast rhythm called supraventricular tachycardia, where the heart rate jumps suddenly to 150 or higher. They’re less useful for the occasional skipped beat. It’s worth discussing these maneuvers with your doctor before relying on them so you know whether they’re appropriate for your particular pattern.
Symptoms That Need Urgent Attention
Most palpitations are harmless, but certain combinations of symptoms suggest something more serious. Palpitations accompanied by chest pain, fainting or near-fainting, severe shortness of breath, or prolonged dizziness warrant prompt medical evaluation. A heart rate that stays above 150 beats per minute for more than a few minutes, or palpitations that come with a feeling of pressure or tightness in the chest, also justify getting checked quickly. The palpitation itself is rarely the danger. It’s the context around it that matters.
