Always healthy heart beats over 100,000 times / day, 10 million times / year, beating the average lifetime of 3 billion times. If you do not understand the reality of the heart rate, we are easily fooled. Here are the heartbeat misunderstanding.

Tachycardia = tremendous pressure

High pressure will increase resting heart rate weeks (resting heart rate is normally 70-80 times / minute), sometimes will make your heart rate increase of up to 100 times / per hour, causing the heart to beat too fast.

But the pressure is only one of many causes accelerated heartbeat. Smoking, coffee intake, dehydration, anemia itching and also lead to increased heart rate.

 

 

Erratic heart rate = heart disease

Just not accompanied by chest tightness, chest pain, shortness of breath, sometimes feel heart palpitations or accelerated heart rate is normal phenomenon.

Gordon Masai Professor, School of Medicine Johns Hopkins University, has said, although the majority of heartbeats is not fully constituted dangerous, but if the recent detection of arrhythmias and occur frequently, you should immediately to the doctor.

Slow heartbeat = weak heart

We often said that the heart beats too slowly will increase the risk of cardiac arrest. The reality is quite the opposite. Heart rate like other parts muscle, cardiac muscle through exercise must to strengthen.

As healthy heart muscle, increasing the cardiac output, less the number of times the heart beats, blood can transmit to the whole body. The resting heart rates below 60 beats (bradycardia) certainly very healthy heart. However, some older people have slow heart rate may be due to symptoms of a heart attack.

A healthy heart rate = 60-100 beats / minute

60-100 beats / minute is the normal heart rate range of adults. But most researchers say, even in the normal range, if the heart rate is high and there is great relevance to ischemic heart disease, stroke and sudden death.

A recent study of Norwegian findings, heart rate increased by 10 beats / min, increasing the risk of heart disease, corresponding to 10% and 18%.

 

Normal heartbeat = normal blood pressure

Heart rate and blood pressure are two different things, between two things not simply be equated with each other. People with normal resting heart rate may also have high blood pressure. Some abnormal heart rhythm, but it's perfectly normal blood pressure. Activity tired body will cause rapid heartbeat, changes in blood pressure, but not great.
