It means that the heart's natural pacemaker isn't working right or that the electrical pathways of the heart are disrupted. Sometimes, the heart beats so slowly that it doesn't pump enough blood to meet the body's needs. This can cause symptoms, such as feeling dizzy or weak. In some cases, it can be life-threatening.

If your heart is beating more than 90 times per minute, it may be struggling. You could be having a panic attack, but shortness of breath plus a rapid heart rate may be a sign of almost any significant heart or lung disease.

If the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs. One troublesome arrhythmia that MVP can cause is atrial fibrillation (AF).
65187
A heart rate that's too slow can cause insufficient blood flow to the brain. Symptoms of bradycardia include: Fatigue or feeling weak. Dizziness or lightheadedness.

Heart disease: Some types of heart disease, such as high blood pressure, are risk factors for AFib, which is a type of arrhythmia. Scarring or abnormal tissue deposits can also cause bradycardia (slow heart rate) or tachycardia (rapid heart rate) by interfering with the heart's electrical system.

Other causes of low blood pressure include medicines, bleeding, aging, and conditions such as dehydration, pregnancy, diabetes, and heart problems. Older adults have a higher risk for symptoms of low blood pressure, such as falling, fainting, or dizziness upon standing up or after a meal.

CAUSES. Bradycardia can occur for several reasons. Common causes of bradycardia include: Congenital heart disease (i.e., condition you were born with)
226829
Causes. Causes of tachycardia include: Heart-related conditions such as high blood pressure (hypertension) Poor blood supply to the heart muscle due to coronary artery disease (atherosclerosis), heart valve disease, heart failure, heart muscle disease (cardiomyopathy), tumors, or infections.

Even emotions, temperature, and humidity outside can affect your pulse rate. A lower resting heart rate is better when it comes to your health. It's a sign your heart is working well. When it's lower, your heart pumps more blood with each contraction and easily keeps a regular beat.

Having bradycardia (say "bray-dee-KAR-dee-uh") means that your heart beats very slowly. For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy.

Your heart might beat faster, slower or differently than usual for a few reasons. Rapid, fast heartbeat at rest could be caused by stress, caffeine, alcohol, tobacco, thyroid pills, cold medication, asthma drugs or diet pills.

A lack of sleep may also cause a person to feel that their heart rate is higher than usual. Sleep disturbances or not getting enough sleep may cause a number of health issues. The next day, the person may also feel that their heartbeat is slightly faster.
22442
In these cases, you faint because of: The vasovagal reflex, which causes the heart rate to slow and the blood vessels to widen, or dilate. This reflex can be triggered by many things, including stress, pain, fear, coughing, holding your breath, and urinating.

The most common causes for a weak or absent pulse are cardiac arrest and shock. Cardiac arrest occurs when someone's heart stops beating. Shock happens when blood flow is reduced to vital organs. This causes a weak pulse, rapid heartbeat, shallow breathing, and unconsciousness.

Medical conditions such as thyroid disease, low blood sugar, anemia, and low blood pressure also may cause palpitations. Heart palpitations may be a sign or symptom of arrhythmia, an irregular heartbeat, or other heart conditions such as heart attack, heart failure, heart valve disease, or cardiomyopathy.
