3 myths how the heart should work

Heart myths

Heart myths

While human affairs, food is made daily activities and sleep, his heart constantly and seamlessly works. It beats with a frequency of 100,000 beats per day, 37 million per year and around 3 billion impact in the life. His work is not always steady. It is likely that sometimes the pulse to be amplified for no apparent reason. You might occasionally feel palpitations or how your heart jumps. When this happens, ask yourself: Is it Normal? At first glance this question seems elementary, but actually is not so, especially if you are not aware of at least the most important facts about heart rate and rhythm. Below are five common and widespread misconceptions and the truth about them.
Myth № 1: irregularly heartbeat means that going through a heart attack
It almost never is. Even if sometimes it is quite normal to feel how your heart skips beats or irregular. If the heart rhythm track of every person long enough you will notice that his heart sometimes skips or reduced further. In the absence of accompanying symptoms (of pain behind the sternum or shortness of breath), these phenomena do not mean anything, much less attack. If the feeling of palpitations or jumping is new to you or is often lately, this may indicate the presence of irregularly heartbeat (arrhythmia). Most of arrhythmia are relatively harmless. This does not mean, however, that should be ignored completely. Some types of irregularly heartbeat can put you at increased risk of heart attack, cardiac arrest and sudden death. It is important to tell your family doctor about your heart irregularly, especially if it is new or frequent relapses. Irregular heartbeat atrial of the heart are more common and fortunately with a better prognosis, while the cameras are more dangerous. The most common arrhythmia, atrial fibrillation are at increased likelihood that the occurrence of further heart attack. Atrial fibrillation to be able to prove the conduct of electrocardiogram (ECG).
Myth № 2: fast heartbeat means that you have a lot of pressure
Stress can really often your pulse, sometimes forcing the heart to beat more than 100 times per minute – a condition called tachycardia. But smoking or consuming caffeine can also cause rapid heartbeat and dehydration, fever, anemia and thyroid diseases. Anyone experiencing tachycardia for no particular reason, should consult a doctor. Even values of heart rate around the upper limit of normal may be disturbing. Practice has shown that heart rate above 85 beats per minute in calm condition may be a symptom of more serious health condition. Furthermore, the cause of tachycardia is often irregular heart activity. In some cases, heart to increase to 200 beats per minute, then cause symptoms such as shortness of breath, chest pain, dizziness and pale. When the heart rate rises above 130 beats per minute for a long time, pumping function of the heart weakens. The good news is that losing weight is suspended after the normalization of the pulse. This is usually achieved with drug therapy or procedures in which the heart reaches the brief high voltage. Some patients even require the destruction of small areas of cardiac tissue where it originated irregular heartbeat.
Myth № 3: healthy heart at rest beats at a frequency of 60 to 100 beats per minute
Right, this is normal heart rate for adults. But the upper frequency range that may present an increased risk of serious health problems.
A large number of studies have demonstrated that increased heart rate constant (even at the upper limit of normal) increases the risk for the following diseases:
• ischemic heart disease;
• heart attack;
• sudden cardiac death.
Recently a group of Norwegian scientists have found that any increase in heart rate with a 10 minute beats and increased risk of heart attack – women 18% and for men – 10 percent. In addition, a recent Japanese study suggests that pulse higher than 80 beats per minute at rest is associated with higher risk of obesity and heart disease in the future. On the other hand, diabetes and obesity are risk factors for heart.
These studies have not shown that high resting pulse causes a heart attack, obesity or diabetes, but in combination with other risk factors it may lead to a predisposition.
However, the optimal values of heart rate and when it risks to our health? None yet reached consensus on the answers, but most doctors agree with the fact that heart rate above 90 beats per minute is unsafe.
To determine your heart rate at rest, worried forefinger and middle finger of one hand on the bottom of the wrist under the thumb of the other. Press gently so as to feel a pulse. Count strokes per minute or 30 seconds, then multiply by two. To be at rest, provide their full 10 minute break prior to measurement.
