I feel a fast heart and shortness of breath, what can it be?

Expert answer:

Accelerated heart and shortness of breath, for no apparent reason, may be symptoms of heart diseases or respiratory, such as arrhythmia, heart failure, bronchitis, asthma, among others. In such cases, the heart can trigger even when the person is at rest, without internal or external stimuli.

However, increased heart rate and shortness of breath can have several causes and do not always indicate the presence of any disease or health problem.

The heart can beat faster due to stress, anxiety, strong emotions, use of medications, consumption of alcoholic beverages or stimulants, smoking, dehydration, physical exercise, among other situations.

Already the lack of air can be due to anxiety, anguish, panic syndrome, lack of physical conditioning or even muscular weakness.

However, there are several diseases and conditions that can cause heart rate (tachycardia), such as arrhythmias, genetic factors, dehydration, lack of blood sugar (hypoglycemia), fever, anemia, hyperthyroidism, infections, among others.

If it is not related to emotional factors or physical effort, shortness of breath can be a symptom of heart or respiratory disease, such as heart failure, influenza, bronchitis, asthma, emphysema, rhinitis, sinusitis.

Therefore, to feel short of breath and the beating heart can be a normal reaction of the body to certain stimuli. However, it is important to note if shortness of breath and increased heart rate occur at rest, in the absence of stimuli, or are accompanied by other symptoms.
