Buna,
Sa stii ca si eu am tahicardie, si persista si zile la rand. Insa nu e un motiv de ingrijorare, pentru ca nu e periculoasa. Inima e cel mai puternic muschi din corpul uman, si e facuta sa reziste la mult mai mult decat crezi.
Mai jos am copiat pasaje legate de tahicardie, dintr-o carte numita "The Anxiety and Phobia Workbook"- Edmund J. Bourne. Daca e greu de inteles in engleza, poti sa pui textul in google translate.
A panic attack cannot cause heart failure or cardiac arrest. Rapid Heartbeat and palpitations during a panic attack can be frightening sensations, but they are not dangerous. Your heart is made up of very strong and dense muscle fibers and can withstand a lot more than you might think. According to Claire Weekes, a healthy heart can beat 200 beats per minute for days even weeks, without sustaining any damage. So if your heart begins to race, just allow it to do so, trusting that no harm can come of it and your heart will eventually calm down.
There is a substantial difference between what goes with your heart during a panic attack and what happens in a heart attack. During a panic attack, your heart may race, pound and at times miss or have extra beats. Some people report chest pains, which pass fairly quickly, in the left upper portion of their chest. None of these symptoms is aggravated by movement or increased physical activity. During a true heart attack, the most common symptom is continuous pain and a pressured, even crushing sensation in the center of your chest. Racing or pounding heart may occur, but this is secondary to the pain. Moreover, the pain and pressure get worse upon exertion and may tend to diminish with rest. This is quite different from a panic attack, where racing and pounding may get worse if you stand still and lessen if you move around.
In the case of heart disease, distinct abnormalities in heart rhythm show up on an electrocardiogram (EKG) reading. It has been demonstrated that during a panic attack there are no EKG abnormalities , only rapid heartbeat. (If you want to be sure you have no heart disease, you may want to have your doctor perform and EKG)
In sum, there is simply no basis for the connection between heart attacks and panic. Panic attacks, are not hazardous to your heart.

There is an important difference between people who have panic attacks and those who do not. Individuals who are prone to panic have a chronic tendency to interpret slightly unusual or uncomfortable bodily sensations in a catastrophic way. For example, heart palpitations are seen as signals of an impending heart attack, chest constriction and shortness of breath are seen as signs of imminent suffocation, etc. People who do not have panic attacks may notice (and not particularly like) having such bodily symptoms, but they do not interpret them as catastrophic or dangerous.
If you have a tendency to interpret unpleasant bodily sensations as something dangerous or catastrophic, you will also tend to constantly monitor your body to see if you are having those sensations. You are probably very tuned in to your internal bodily states and overreact easily if something begins to feel slightly off or unusual. The increased internalisation creates a problem because you will notice and magnify any sudden change in your body that is slightly unusual or unpleasant.
The variety of circumstances that might cause a sudden change in your body's internal physiological state is numerous. Sometimes the cause lies outside of your body. For example, an argument with your spouse, seeing something unpleasant in TV, hearing your alarm clock, being in a hurry to be somewhere can trigger an increase in heart rate, chest constriction, stomach queasiness, or any of a wide range of bodily symptoms associated with anxiety.
At other times, the cause resides in some subtle physiological shift within your body - for example oxygen deprivation due to under-breathing, a spontaneous shift in the neuroendocrine systems of your brain, an increase in muscle tension, or a fall or a spike in your blood sugar level. These are just a few examples and all can cause racing heart and various other symptoms. Other times your thoughts can produce various symptoms.
Whether the initial cause lies primarily outside or within your body, you are usually unaware of these physiological shifts until you feel the resultant symptoms. The above examples illustrate only a few among many possibilities, any of which might constitute the triggering event for an increase in anxiety. Whether or not you actually develop a panic attack depends on how you perceive and respond to the particular increase in body symptoms that occurs.
To sum up, people who panic are likely to experience: 1) increased internalisation and preoccupation with subtle shifts in bodily symptoms or mood and 2) an increased tendency to interpret slight changes in bodily symptoms as dangerous and catastrophic.
Diagram of a panic attack triggered by racing heart:
Phase1. Initiating circumstances (internal or external)
Phase2. Slight increase in unusual or unpleasant bodily symptoms (eg. heart palpitations)
Phase3. Internalisation (increased focus on the symptoms makes them more noticeable and magnifies them)
Phase4. Catastrophic interpretation (telling yourself that it is dangerous symptom: I will have a heart attack, I will die)
Phase5. Panic
The good news is that it is possible to intervene at any point in this sequence. At phase 1 might be generalised stress, anxiety, or other circumstances where you can interfere by for example incorporating regular relaxation, exercise, stress management, etc in your life. Practicing relaxation exercises every day will result in a generalised effects after few weeks, you will find yourself more and more calm and less stressed during the day.
Phase 3 Consists of internalisation, being too focused on your sensations. When you feel these sensations coming and your anxiety increasing, you can use various techniques that reduce and stop panic. Vezi exemple aici:

Perhaps the most important change you can make to defuse panic attacks is to interfere at phase 4. You can learn to stop interpreting unpleasant body sensations as dangerous or potentially catastrophic. Research has shown that eliminating catastrophic interpretations of body sensations is sufficient to relieve panic attacks. If you can learn to tolerate your rapid heartbeat and other sensations without interpreting them as dangerous, you will not have panic attacks anymore.
In order to break the connection between body sensations and catastrophic interpretations you need to replace your false beliefs that you are in danger or having a heart attack with an alternative explanation to your symptoms. Example of explanation to rapid heartbeat.
"An increase in heartbeat and/or heart palpitations is very likely caused by an increased output of adrenaline and sympathetic nervous system that accompany the early stage of an anxiety reaction, Such reactions are part of the body's normal means of handling any perceived threat- they are part of the fight or flight response. They are in no way dangerous, even if they continue for some time. For example a heart can beat rapidly for hours or days without putting you at any risk.
Another method is to use exposure in order to learn that the symptoms are not harmful:
example: walk up and down some stairs rapidly for about ninety seconds or until your heart rate increases. Stop if you start feeling dizzy or very uncomfortable.
