Palpitation may be a sign of cardiac arrhythmia
The heart beats about 80 times in a minute and no one notices. When the rhythm becomes irregular - too fast or too slow - one often feels something different in the chest. The most common report is palpitations. Sometimes the chest "accelerates", sometimes slows down. Sometimes he jumps. Sometimes it feels like there's someone blowing air bubbles inside a glass on my chest. Sometimes it makes you dizzy or fainting.
Heart rate variation causes some beating to push more blood, some less. This variation in the amount of blood is perceived by the person as if the heart is beating irregularly - because most of the time it is. Imagine an open faucet in a continuous flow filling a bucket. With every full hour you go there and empty the bucket. The amount of water in each empty bucket will be the same, right? Now imagine if a person comes in the middle of the process and empties the bucket - an early beat, also called extra systole. This person tells you, "It's empty, you do not have to come here now." In this way, this bucket fills with the liquid of an entire round, plus the much that was not emptied previously, being therefore with much more liquid. This variation is noticed in the person's body (each bucket is pumped from the heart, right?).
In some situations, palpitation is normal, such as immediately after intense physical exertion. And why do we notice then? Because when we are running the body needs very fast beats to take oxygen and remove carbon dioxide. Immediately after the effort the body no longer needs it. And your heart rate is inadequately elevated. That's why we noticed. So we concluded that we also notice when the heart rate is too high for the little effort we are making (or too slow to take oxygen when we need it.)
This may mean the presence of a cardiac arrhythmia. In some cases, too slow or too rapid a frequency can lead to clots in the heart or lead to poor cerebral perfusion, acute myocardial infarction, and death. Therefore when looking for palpitations in inappropriate situations it is very important to see a cardiologist or an arrhythmologist (cardiac arrhythmia specialist) to evaluate the risk and the best treatment.
High blood pressure is recognized as a risk factor for injury to important organs in our body, such as the kidneys, eyes, brain and heart. On certain occasions, such as hypertension, when blood pressure is high for a long period or when there is delay in diagnosis and treatment, there is a greater risk for cardiac injury.
All cancers are genetic, but less than 10% of all cancers are hereditary, that is, transmitted from parents to their children. Cancer is a disease that depends heavily on environmental factors and lifestyle habits, and is not really hereditary in the strict sense of the word. Heredity means you definitely get a familiar trait like eye color or a genetic disease.
