what does it mean when your heart rate is elevated?

In tachycardia, an abnormal electrical impulse starting in the upper or lower chambers of the heart causes the heart to beat faster. Tachycardia is the medical term for a heart rate over 100 beats per minute. There are many heart rhythm disorders (arrhythmias) that can cause tachycardia.

People who exercise regularly often have lower resting heart rates. In some situations, such as periods of acute stress or danger, blood pressure and heart rate may both increase at the same time, but that's not always the case. Your heart rate can increase without any change occurring in your blood pressure.

After exercise, the body's adrenaline level remains high for a period of time while the heart rate decreases back to normal. Due to the higher adrenaline level in this time period, the palpitations can occur at an increased rate or frequency.

Prolonged stress can also cause resting heart rate to creep up, and the associated increase can result in a higher risk of heart attacks and stroke.

Elevated heart rate is associated with elevated blood pressure, increased risk for hypertension, and, among hypertensives, increased risk for cardiovascular disease. Despite these important relationships, heart rate is generally not a major consideration in choosing antihypertensive medications.

A heart rate is the number of times your heart beats in the span of a minute. A pulse rate is the number of times your arteries create a noticeable “pulse” due to increase in blood pressure as a result of your heart contracting.

Within the first ten minutes your heart rate increases meaning there is an increased supply of blood to the brain, making you more alert, blocking pain signals and then the body will use different energy systems depending on the duration and intensity of the exercise.

Hard exercise, anxiety, certain drugs, or a fever can spark it. When it happens for no clear reason, it's called inappropriate sinus tachycardia (IST). Your heart rate might shoot up with just a little movement or stress. Or it might be high when you're doing nothing.

Other factors that affect your resting heart rate are: air temperature (high temps and humidity can increase pulse), body position (BPMs can go up right when you stand up), and medication, such as beta blockers that block adrenaline and can slow the pulse.

“Pounding” in Your Chest or Ears If you have a sensation of pulsing or pounding in your ears or in your chest when you haven't been exercising vigorously, this could indicate an elevated blood pressure. It could also be related to drinking too much caffeine, so try cutting back on the coffee and soda.

When heart rate is too high Going higher than your maximum heart rate for long periods of time could be dangerous for your health. That's especially true if you're new to exercise.

Tachycardia refers to a heart rate that's too fast. How that's defined may depend on your age and physical condition. Generally speaking, for adults, a heart rate of more than 100 beats per minute (BPM) is considered too fast. View an animation of tachycardia.

During a hot summer day, if you notice a temporary increase in your resting heart rate, your body might simply be trying to cool down. However, it could also mean you're dehydrated—especially if you're thirstier than usual, your mouth is dry, and your pee is more yellow than normal.

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.

Many people experience palpitations before and after exercise, but not during exercise. When most people start to exercise, their own heart rate increases and the palpitations, or extra beats, disappear at this higher heart rate.

A common cause of a rising heart rate during sleep is a lack of oxygen, which is often brought on by obstructive sleep apnea. This is a condition where a person's normal breathing frequency is reduced or sometimes flat-out stopped during sleep.

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. When you exercise, your heart speeds up so more blood can reach your muscles.
