Lately my heart has been beating exceptionally fast! It's actually quite scary. Even when I'm sitting down, it still goes popop.. popop.. popop.. beating very hard, very rapid..
So I went to check out on what's "a rapid heartbeat". It's defined as a heart rate that is faster than normal. Haha.. Talk about the obvious! But it did indicate that normal range is usually 50 to 100 times per minute in adults & slightly faster in children; & with increased physical activity, stress, or other conditions, however, the heart rate may increase above the normal level.
I wanted to know the symptoms. It seems that sometimes a person with a rapid heartbeat may have no symptoms at all! Then how?? Haiz..
But some symptoms may include:
~ palpitations, or an unusual awareness of the heartbeat
~ excessive sweating
~ fatigue or weakness
~ shortness of breath
~ chest pain
~ lightheadedness or dizziness
~ fainting
Possible causes of a rapid heartbeat are simply too many.. To name a few more relevant ones:
~ exercise, heavy lifting or other activity that requires exertion
~ fear, pain, anxiety, stress, anger, or nervousness
~ hyperthyroidism, which is a level of thyroid hormone in the body that is too high
~ congestive heart failure, a condition in which the heart cannot pump blood effectively
~ irregular heartbeats, known as arrhythmias, such as atrial fibrillation or ventricular tachycardia. These may be caused by salt imbalances, heart attack, and other conditions.
~ low red blood cell count known as anemia
~ low oxygen in the blood, also called hypoxia
Other causes are possible. Sometimes, no cause can be found.
The article says that in the longrun, this condition will have certain long-term effects. If the heart beats too quickly, it may not be able to pump blood well enough to keep a person alive. Most long-term effects are related to the cause. For example, rapid heartbeat due to anxiety or exercise often goes away quickly & has no long-term effects. Rapid heartbeat due to an arrhythmia or sepsis may sometimes result in death.
I wonder what's the cause of my rapid heartbeat. I counted.. my heart rate is around 100-110 now even as I'm sitting down. My doctor actually suspects that because mine is a "sudden awareness" of my heartbeat, it could be due to hormonal imbalance. To her, this could also be a menopausal symptom. I really don't know. I feel that it's weight- & environment-related issue.
So for now will have to wait & see what'll happen next. Perhaps I may jz collapse one fine day lor :)
