What Causes the irregular Heart Beat and Palpitations

heart fluttering

Most people don’t even realize that they are having heart palpitations. It’s one of those conditions that has its own peculiar way of affecting the individual. The most common symptom of heart palpitations is that the individual will experience shortness of breath, which can be very severe especially when it happens right after doing a physical activity.

People with heart fluttering symptoms may feel like they are in a dream state. They may feel as if something is going to happen to them at any second and they just don’t know what. It’s like an out-of-body experience. Whenever they think they’re about to get some sort of workout or they’re physically exercising, they can feel as if their heart is beating a thousand miles per minute and they just can’t seem to slow it down no matter how hard they try.

Caffeine Increases The Levels Of Norepinephrine

Some people experience heart fluttering even though they are already suffering from arrhythmias. It is actually caused by a build-up of caffeine from coffee or tea. Caffeine has been found to stimulate adrenaline production. In this case, the individual will have a racing heart beat. The caffeine also increases the levels of norepinephrine which causes palpitations. If they drink a large amount of coffee, it may turn into something else; it may even lead to caffeine addiction.

People who use energy drinks may also experience heart fluttering because of the stimulant in the drinks. The caffeine in the energy drinks can cause the heart rate to increase in short periods of time and the individual will feel like they need more exercise to get rid of the excess energy. This will increase their heart rate even further and cause an irregular heartbeat. Many people experience arrhythmias caused by caffeine and energy drinks all the time.

Overactive Thyroid

Background pattern

Another factor that can cause heart fluttering is an overactive thyroid. People with an overactive thyroid gland will have palpitations. An underactive thyroid will cause the heart to flutter. Hypothyroidism and hyperthyroidism are the two most common causes of heart palpitations. People who have hyperthyroidism may hear a clicking sound when they have their heart beats.

Sometimes heart fluttering is caused by low blood sugar. The low blood sugar will cause irregular heart beat. This irregular heart beat will disrupt the rhythm of the heart in some instances, causing heart palpitations. This can be very dangerous and if this occurs it is imperative that you consult a physician immediately. Other causes of heart fluttering include the presence of congenital defects, menopause, cardiac stress, anxiety disorders and hypertension.


Medications include beta blockers and diuretics. Medications are needed to keep the atria from collapsing or going into ventricular fibrillation. Some people may experience heart fluttering after receiving cardiac treatments like percussion. Cardiac stress can also cause irregular heartbeat and palpitations. Patients who are undergoing coronary artery bypass surgery or mitral valve repair have been known to experience heart fluttering after the surgical procedure.

It is important to identify the causes of your heart fluttering so that you can be able to determine which of the mentioned causes is the cause of your heart beating irregularly. If it is not the cardiac stress or the medication that is making your heart beat too fast, you will need to consult your physician for proper diagnosis.

Know The Type Of Treatment After Analysing Problem

The treatment that you receive will depend on what is really causing your problem. If you find out that you are suffering from hypertension, you will need to lower your blood cholesterol in order for you to prevent your heart fluttering.

Final Verdict

If you found out that the cause is due to an abnormal congenital heart defect, your doctor will have to perform a heart transplant in order for you to undergo heart bypass surgery.
