In general, a resting adult heart beats between 60 and 100 times per minute. When an individual has tachycardia, the upper or lower chambers of the heart beat significantly faster. When the heart beats too rapidly, it pumps less efficiently and blood flow to the rest of the body, including the heart itself, is reduced.

When to see a doctor You should visit your doctor if your heart rate is consistently above 100 beats per minute or below 60 beats per minute (and you're not an athlete). In addition to a heart rate, you should look out for other symptoms such as: being short of breath. fainting.

When heart rate or rhythm changes are minor Your heart rate or rhythm can change when you are under stress or having pain. Your heart may beat faster when you have an illness or a fever. Hard physical exercise usually increases your heart rate, which can sometimes cause changes in your heart rhythm.

Generally, for adults, a heart rate of more than 100 beats per minute (tachycardia) is considered as high.

Tachycardia refers to a fast resting heart rate, usually over 100 beats per minute. Tachycardia can be dangerous, depending on its underlying cause and on how hard the heart has to work. Some people with tachycardia may have no symptoms or complications.

Weight plays a part. Weighing too much or too little can elevate a person's resting heart rate. Body size doesn't have a huge impact on pulse overall, but if a person is obese, they might see a higher resting pulse than normal, but usually not more than 100.

Prolonged mental and emotional stress can also cause your resting heart rate to creep up over time. If “fight-or-flight” mode becomes your norm, the associated increase in your resting heart rate can produce a higher risk of heart attacks, strokes, and much more.

Heart rate and blood pressure do not necessarily increase at the same rate. A rising heart rate does not cause your blood pressure to increase at the same rate. Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily.

The hormone adrenaline floods into your bloodstream, putting your body on high alert. Your heartbeat quickens, which sends more blood to your muscles. Your breathing becomes fast and shallow, so you can take in more oxygen. Your blood sugar spikes.

When you walk fast or run, your heart rate increases as it pumps more blood to power your muscles. More blood pumping through your vascular system means more pressure on the walls of your blood vessels. That causes your blood pressure to temporarily rise, says Dr.

When blood pressure rises too high, baroreceptors fire at a higher rate and trigger parasympathetic stimulation of the heart. As a result, cardiac output falls. Sympathetic stimulation of the peripheral arterioles will also decrease, resulting in vasodilation. Combined, these activities cause blood pressure to fall.

The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. As the heart pushes blood through the arteries, the arteries expand and contract with the flow of the blood. Taking a pulse not only measures the heart rate, but also can indicate the following: Heart rhythm.

Tachycardia is a heart condition where one's heart is beating too fast, more than 100 beats per minute when at rest. In general, normal resting heart rate is between 60 and 100 beats per minute while with tachycardia, the heart's chambers are working too hard and beating faster than is considered healthy.

The disruption of the normal electrical impulses that regulate the heart rate and pumping rhythm get out of sync and the cause the heart to beat faster. There might be several underlying causes why this might happen including reaction to certain medication, birth defects, alcohol use, hypertension and many others.

This extra blood results in a heart rate that's about 25 percent faster than usual. A faster heart rate can result in occasional heart palpitations. These feel like your heart is fluttering or beating extremely fast. Heart palpitations can be normal and nonharmful during pregnancy.

Numerous studies have shown that higher resting heart rate is associated with increased risk of cardiovascular events and death in men and women, Fonarow said. However, whether higher heart rate is a marker of poor physical fitness or heart disease isn't clear, he added.

When you walk fast or run, your heart rate increases as it pumps more blood to power your muscles. More blood pumping through your vascular system means more pressure on the walls of your blood vessels. That causes your blood pressure to temporarily rise, says Dr. Kaplan.
