Is a pulse of 77 normal?

The pulse rate of an adult is usually 70-80 beats per minute, and the pulse frequency is affected by factors such as age and gender. If the pulse is 77, it is within the normal range. It is normal for the pulse to be temporarily abnormal due to the influence of human activities. If your pulse is abnormal and you feel uncomfortable, it is best to go to the hospital to check the specific cause. A pulse that beats too fast or too slow for a long time is unhealthy and can easily cause a variety of diseases, so it should be taken seriously.

Is a pulse of 77 normal?

A normal person's pulse and heartbeat are consistent. The pulse rate is affected by age and gender, 120-140 beats per minute for infants, 90-100 beats per minute for toddlers, 80-90 beats per minute for school-age children, and 70-80 beats per minute for adults. The pulse rate is 77/min, which should be normal. Measure the heart rate if necessary.

Causes of abnormal pulse

Of course, a normal adult's pulse will transiently speed up after exercise, after a meal, after drinking, or when excited, but it will quickly return to normal. The pulse rate of long-term physical exercisers and athletes is slower. When sleeping at night, blood circulation slows down and the pulse is also slower.

The dangers of a fast pulse

If an adult's pulse rate at rest exceeds 80 beats/minute, it means that the heart rate is too fast. If it exceeds 100 beats/minute, it is tachycardia. A too fast heart rate can cause a lot of trouble, such as increasing the burden on the heart and oxygen consumption, and the probability of such people suffering from cardiac arrest and sudden death is higher than normal people, so the heart rate must be lowered.

The dangers of a slow pulse

However, a slow pulse is not a good thing. A pulse of less than 55 beats per minute is considered a slow pulse, which is more common in people who engage in physical labor for a long time and athletes. Some diseases can also cause a slow pulse, such as atrioventricular conduction block, cardiac pacemaker dysfunction, increased intracranial pressure, etc. At this time, you should seek medical attention in time, find out the cause, and treat it symptomatically. Do not turn a blind eye to it, otherwise serious conditions such as cardiac syncope may occur.

Pulse other indications

Irregular pulse rate: that is, the pulse beats at different speeds, which is seen in various heart diseases.

Pulse alternating: The rhythm is normal, with alternating strong and weak pulses, which is the result of the heart's strong and weak contractions. It is common in hypertensive heart disease and coronary artery sclerosis.

Increased pulse and large amplitude: due to large cardiac volume, wide pulse pressure and low peripheral resistance, it is common in diseases such as high fever, hyperthyroidism, aortic valve insufficiency, etc.

Weak pulse and low amplitude: This is caused by low cardiac volume, low pulse pressure and increased peripheral resistance. It is common in diseases such as heart failure, aortic valve stenosis and shock.
