Panic Breathing: What is Hyperventilation Syndrome?

With sudden breathing, every heartbeat sounds like a thunderclap, and sweating becomes more intense. Many people mistake these symptoms for a heart attack. If this is a regular occurrence, it is most likely hyperventilation syndrome. In most cases, hyperventilation (rapid and shallow breathing) goes hand in hand with anxiety or panic disorder. It occurs more often in women than in men. This condition does not threaten your life, but it significantly affects the quality of life.
