Why Does Your Chest Muscle Keep Twitching?

Some people describe it as a twitch, a flutter or even a spasm they feel deep in their chest. Sometimes so deep the concern could be a heart condition or worse a heart attack.

That thought alone can give a person an anxiety attack, another cause for the sudden sensation of a twitch or flutter felt in the chest.

Until you remember that you weight trained your chest or was lifting heavy objects the day before and think maybe that is the cause?

Chest flutters or twitches are common for people of all ages. However, there are considerations to be made when determining if the sensations you are experiencing are of a serious nature and require medical attention.

The Cause Might Surprise You

The truth is it could be any one of those things (heart issue, anxiety/stress or muscle spasm related to muscle strain) and possibly even more.

The twitch you are feeling might be a simple muscle spasm (although it seems very deep) or it could be something much more serious like a heart condition that requires urgent attention.


Weight Training or Heavy Lifting – Have you been hitting it hard at the gym? Or maybe you helped a friend move yesterday? This could easily be the source of the twitching sensation you are experiencing.

Even though the sensations seem very deep in your chest, it might feel like the twitch is coming from under your pectorals major muscle. There are two muscles under the pectorals major.

They are the pectorals minor and the intercostal muscles. Neither of them really do enough to be the cause of the twitch; however, the twitch could easily be coming from a deeper part of the pectorals major.

Anxiety or Stress – Twitches in the chest can also be a symptom of anxiety or stress. Spasms, flutters or twitches in your chest as a result of an anxiety attack are as unpredictable as an anxiety attack itself.

You may not even have any other symptoms other than the muscle twitches and you might not even be aware that you are having an anxiety attack.

There might be a few twitches or a lot of twitches. They might last a few seconds, a long time or come and go.

People that know they have anxiety are usually aware that chest twitches or flutters are a symptom of anxiety.

People that have not been diagnosed with anxiety can have a very frightening experience if they are encountering both chest twitches and other symptoms of an anxiety attack.

If you think you have experienced an anxiety attack or are having concerns that you are not coping with stress, it is important to have a more detailed conversation with your doctor.

There may be an underlying cause that is adding to your anxiety that is medically treatable.

Symptoms of an Anxiety Attack:

  • Feeling a loss of control
  • Chest pains/flutters/twitches
  • Muscle twitches (including chest area)
  • The Overwhelming sense of doom or fear

Heart Conditions – There are a number of heart conditions that could cause chest twitches.

Here are some things you should know about heart attacks: 

  • The most common symptom is chest pain. Most heart attacks include a pain or discomfort in the center of the chest. The pain can last for an extended period of time or can go away and then come back. The sensation can also feel like a pressure across your chest or a squeezing feeling.
  • You could experience pain in other areas of the body that are indicative of a heart attack. The pain could be in one or even both arms, your neck, jaw, or back.
  • You may also experience a shortness of breath or difficulty with breathing. Difficulty breathing during a heart attack can occur with or without chest pains/twitches/flutters.
  • Other symptoms of a heart attack include; feeling lightheaded, breaking out in a cold sweat and/or nausea.
  • Symptoms of a heart attack last longer than 30 minutes.
  • The heart attack symptoms noted here can also vary between men and women. It is also worth mentioning that women are more likely to experience chest discomfort (including twitches in the chest muscle).
  • If you think you are having a heart attack, the only way to know for sure is to be seen by your physician and have tested.
  • If you already know you have an increased risk of a heart attack, it is important to consult your doctor if experiencing any of these symptoms as described

Chest Muscle Twitching Or Heart

Fasciculation or muscle twitching is what happens when minor local muscles contract.

Twitching could also result if one muscle group that is served by one motor nerve filament or fiber misfires.

This could happen to fibers or bundles of muscles in the pectoralis.

The twitching is usually triggered by a particular muscle that is overused causing it to suffer depletion of its required electrolytes or ions.

Muscle twitching, according to Just Answer.com is often a benign condition. The stimulation of an efferent nerve can also cause muscle twitching.

Other causes of muscle twitching include drinking undue amounts of caffeinated drinks, deficiency of B vitamins, lack of minerals such as magnesium, calcium, and potassium, and the intake of medications such as steroids and diuretics.

What Causes Heart Muscle Spasms?

The cause of heart muscle spasm, according to Healthline.com is the abrupt tightening of arterial muscles of the heart.

When it happens, the arteries will narrow preventing the blood from flowing to the heart.

Thankfully, these spasms only occur very briefly and are only temporary in nature.

But if the cause is not addressed, it may lead to more serious complications such as a heart attack.

Those who have existing heart conditions such as high blood pressure or high cholesterol levels are at higher risks than those who don’t.

Heart muscle spasms are also called contractions of the coronary artery. The common symptoms of this condition are feelings of constriction, chest tightness, pain on the left portion of the chest, angina and chest pain.

You will know if you have spasms in your coronary artery if your chest pains usually happen early in the morning or at night, or if the pains usually last from five minutes or as long as 30 minutes, or if you experience the spams while you are resting.
