I have tachycardia every now and then along with shortness of breath; it happens for no reason. I'm scared I won't be able to breathe one day. Why does this happen? Should I see a doctor?

Dr. Rania Mousa General Medicine
A number of conditions can cause a rapid heart rate and tachycardia symptoms. It's important to get a prompt, accurate diagnosis and appropriate care.Proper diagnosis is very important,since the severity of tachycardia ranges greatly,the cause may be as simple as having caffeine sensitivity leading to tachycardia and may be more severe and complicated associated with heart problems or lung problems,the causes vary and depends on the onset,how long this had been and other symptoms ,the doctor can determine the cause and the proper diagnosis through physical examination ,blood tests and other investigations
A healthy adult heart normally beats 60 to 100 times a minute when a person is at rest. Tachycardia is an abnormally rapid beating of the heart, defined as a resting heart rate of over 100 beats per minute.
Since the heart and lungs work together in a close relationship, a problem with one of these organs almost always affects the other.tachycardia and SOB(shortness of breath)are strongly related
Many things can cause or contribute to problems with the heart's electrical system. These factors include:
-Damage to heart tissues from heart disease
-Abnormal electrical pathways in the heart present at birth (congenital)
-Disease or congenital abnormality of the heart
-High blood pressure
-Smoking
-Fever
-Drinking too much alcohol
-Drinking too many caffeinated beverages
-A side effect of medications
-Abuse of recreational drugs, such as cocaine
-Imbalance of electrolytes, mineral-related substances necessary for conducting electrical impulses
-Overactive thyroid (hyperthyroidism)
and there are several types of tachycardia ,you need to be seen by a cardiologist
