Frequent rapid heartbeat, chest tightness and chest pain all the time, are these heart diseases?
The heart is the main organ in the body, beating all the time, powering the flow of blood and transporting it to all parts of the body, but it is the most susceptible to pathology. The dangers of heart disease are widely known, but the symptoms are not well understood and often mistaken for heart disease because of chest tightness and pain, sudden panic attacks or a rapid heart rate that makes it difficult to sleep and eat.
