Yes lybrate-user,
you are suffering from phobic anxiety. It is panic attack which you translate it as nearing heart attack. Panic is panic it never will turn into heart attack you must have noticed panic attack last for few minutes and then subsides.
Anxiety is fear. It's the activation of the fight or flight system, which is the system that your body uses to react to fear responses. Anxiety disorders occur because the body is activating that response when no danger is present. But in addition to being fear, anxiety also causes other fears. That's one of the reasons that anxiety can be hard to treat without help. One of the fears it causes is a fear of cardiovascular problems (poor heart health), and often those fears end up contributing to further anxiety.
It would be disingenuous to say you do not have a heart condition, because there is no way to know until you talk to your doctor. But let's assume that you're like most people - your doctor is going to tell you that nothing is wrong with your heart. So then why are these cardiovascular problems occurring? the answer is likely to be hyperventilation. Hyperventilation is also known as" over-breathing, and contrary to popular belief, it's not caused by getting too little air. It's actually caused by breathing out too much carbon dioxide. Your body needs the right balance of carbon dioxide to function. When you breathe too quickly (or breathe in more oxygen than your body needs), your cells are drained of their carbon dioxide and your entire body is forced to work much harder in order to function. Your blood vessels constrict, your brain gets less oxygen, and your heart has to beat extra fast because your blood is slowing down. This what causes the vast majority of the symptoms of a panic attack. And what makes it worse is that hyperventilation makes it feel like you're not getting enough oxygen, even though the reality is that you've taken in too much. Because of that feeling, most people continue to hyperventilate even more in order to try to get a" full breath" only to hyperventilate even further and experience a worsening of the symptoms. When you combine these symptoms with anxiety, you get a constant feeling that your heart is in poor health.
The first thing you need to do is practice better breathing. Since hyperventilation causes most of the symptoms, it's important to start breathing more efficiently. Take slow, controlled breaths, and fight the urge to yawn or expand your chest. The moment you start to feel as though a panic attack is coming on, try the following: breathe in slowly, taking at least 5 seconds. Hold for two seconds. Breathe out as though whistling for 7 seconds. Never rush the air out of your body, and try to give yourself time to regain your carbon dioxide level. Don't hold your breath for too long though since holding your breath can cause similar symptoms and may exacerbate your anxiety. Controlling your breathing won't stop your panic attacks, but they should reduce the severity, and for many that alone can help reduce the frequency of panic attacks in the future. Once you've controlled your breathing it's time to combat your overall anxiety, which in turn will decrease your cardiovascular health fears.
