why does my heart beat so fast even when resting

A of more than 100 beats per minute (BPM) in adults is called tachycardia. What's too fast for you may depend on your age and physical condition. Atrial or Supraventricular tachycardia (SVT) Atrial or Supraventricular tachycardia (SVT) is a fast heart rate that starts in the upper chambers of the heart. Some forms are called paroxysmal atrial tachycardia (PAT) or paroxysmal supraventricular tachycardia (PSVT). How it happens Electrical signals in the heart's upper chambers fire abnormally, which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart's natural pacemaker. A series of early beats in the atria speeds up the heart rate. The rapid heartbeat does not allow enough time for the heart to fill before it contracts so blood flow to the rest of the body is compromised. Who is likely to have Atrial or SVT? More common in women, but may occur in either sex
People who drink large amounts of coffee (or caffeinated substances). Serious Symptoms and Complications of Atrial or SVT Angina (chest pain), pressure or tightness In extreme cases, atrial or SVT may cause: Treatment for Atrial or SVT Many people don't need medical therapy. Treatment is considered if episodes are prolonged or occur often. Your doctor may recommend or try: Carotid sinus massage: gentle pressure on the neck, where the carotid artery splits into two branches. Must be performed by a healthcare professional to minimize risk of stroke, heart or lung injury from blood clots. Pressing gently on the eyeballs with eyes closed. But this maneuver should be guided by your doctor. Valsalva maneuver: holding your nostrils closed while blowing air through your nose. Dive reflex: the body's response to sudden immersion in water, especially cold water. Sedation. Cutting down on coffee or other caffeinated substances. Cutting down on alcohol. Quitting tobacco use. Getting more rest. In patients with Wolfe-Parkinson-White syndrome, medications or ablation may be needed to control PSVT. Sinus tachycardia Ventricular tachycardia Ventricular tachycardia is a fast heart rate that starts in the heart's lower chambers (ventricles).


It often occurs in life-threatening situations that dictate rapid diagnosis and treatment. How it happens Electrical signals in the ventricles fire abnormally, which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart's natural pacemaker. The rapid heartbeat does not allow enough time for the heart to fill before it contracts so blood flow to the rest of the body is compromised Causes of Ventricular Tachycardia Usually associated with disorders of the heart which interfere with the normal conduction system of the heart. These disorders may include: Symptoms of Ventricular Tachycardia Consequences of Ventricular Tachycardia This type of arrhythmia may be either well-tolerated or may be life-threatening. The seriousness depends largely on whether other cardiac dysfunction is present, and on the rate of VT. Treatment of Ventricular Tachycardia The type and length of treatment depends on what's causing the problem. If required, treatment may include: Causes of tachycardia Under certain conditions, the automatic firing rate of secondary pacemaker tissue may become too fast. If such an abnormal focus fires faster than the sinus node, it may take over control of the heart rhythm and cause tachycardia. In another type of abnormal conduction, impulses get caught in a merry-go-round-like sequence. This process, called reentry, is a common cause of tachycardia. Symptoms of tachycardia Rhythm may be fast and regular or fast and irregular. Treatments for tachycardia Sudden ventricular tachycardia and ventricular fibrillation are life-threatening. With rapid detection they can be converted into a normal rhythm with electrical shock from a defibrillator.


Rapid heart beating can be controlled over time with medications and by identifying or destroying the focus of rhythm disturbances. One effective way of correcting these life-threatening rhythms is by using an electronic device called an This content was last reviewed September 2016. Fast Heart Rate в When To Worry? By: Experiencing a fast heart rate can be a worrisome occurrence, especially if you are not aware of why it is taking place. Let s take a brief look at some of the basic questions surrounding a fast heart rate, as well as when to take further action. What Is Considered A Fast Heart Rate? The definition of a fast heart rate differs depending on the age of the person experiencing it. Typically, it is defined as have a resting heart rate faster than 100 beats per minute for adults. A fast heart rate is one that is unexpected for a certain level of physical activity. Usually, most adult s resting heart rate usually lies in the range of 60-80 beats per minute, with some heart rates approaching 100 beats per minute. Is A Fast Heart Rate Always A Cause for Concern? There are several different possible causes of an elevated heart rate. While some causes are more worrisome to cardiologists, there are other causes that can be addressed by making lifestyle changes. Some of these include excitement (which stirs up adrenaline), dehydration, and even the consumption of nicotine or energy drinks. There are times that having an elevated heart rate makes sense. For instance, if you are fighting a fever or getting over the flu, or are in the process of recovering form a surgery, a fast heart rate is your body s way of saying it is working. It s important to monitor your heart rate during these times, but do not become immediately alarmed. Fast Heart Rate And Age Concern regarding a fast heart rate is going to differ based on the patient s age and health.


As a general rule, the younger you are, the lower your resting heart rate. As you get older, your resting heart rate increases. Interestingly, however, there are some patients who experience faster and slower heart rates at the same time. This phenomenon can be seen across many age groups. Thus, cause for concern is not 100% definable by age. When To See A Doctor A person experiencing a fast heart rate should take special note of whether or not he is experiencing additional symptoms. Are there are other things going on that could be making someone feel lousy? For example, a person who is experiencing shortness of breath, activity intolerance, palpitations, or extreme fatigue should see a doctor immediately. It s important to note that many people who are experiencing an elevated heart rate don t feel it or associate it with other issues. In other words, it can often take a bit of an investigation to discover the cause. What Is My Role In Checking Out My Fast Heart Rate? If you are concerned about an elevated heart rate, make sure you aren t currently dehydrated, and that you are being treated properly for any related medical condition. If you ve accounted for common causes of an elevated heart rate including reducing or eliminating caffeine and are still experiencing symptoms, make sure to see a doctor as soon as possible. What Are Common Tests/Treatments For A Fast Heart Rate? Common tests and treatments for a fast heart rate include blood pressure measurements, EKGs, and ultrasounds of the heart. A doctor may check to see if your elevated heart rate occurs only with a change in position (i. e. standing up). If so, there could be an imbalance of heart rate and blood pressure control in the body. Treatment for a fast heart rate will vary greatly based on its cause. If you are concerned about an elevated heart rate or have additional questions on the topic, I encourage you to.
