why is my pulse so high at rest
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. What should you know about your heart rate? Even if you re not an athlete, knowledge about your heart rate can help you monitor your fitness level and it might even help you spot developing health problems.
Your heart rate, or pulse, is the number of times your heart beats per minute. Normal heart rate varies from person to person. Knowing yours can be an important heart-health gauge. As you age, changes in the rate and regularity of your pulse can change and may signify a or other condition that needs to be addressed. Where is it and what is a normal heart rate? To get the most accurate reading, put your finger over your pulse and count the number of beats in 60 seconds. Your resting heart rate is the heart pumping the lowest amount of blood you need because you re not exercising. If you re sitting or lying and you re calm, relaxed and aren t ill, your heart rate is normally between 60 (beats per minute) and 100 (beats per minute). But a heart rate lower than 60 doesn t necessarily signal a medical problem. It could be the result of taking a drug such as a. A lower heart rate is also common for people who get a lot of physical activity or are very athletic. Active people often have lower heart rates because their heart muscle is in better condition and doesn t need to work as hard to maintain a steady beat. Moderate physical activity doesn t usually change the resting pulse much. If you re very fit, it could change to 40. A less active person might have a heart rate between 60 and 100. That s because the heart muscle has to work harder to maintain bodily functions, making it higher. Air temperature: When temperatures (and the humidity) soar, the heart pumps a little more blood, so your pulse rate may increase, but usually no more than five to 10 beats a minute.
Body position: Resting, sitting or standing, your pulse is usually the same. Sometimes as you stand for the first 15 to 20 seconds, your pulse may go up a little bit, but after a couple of minutes it should settle down. Emotions: If you re stressed, anxious or extraordinarily happy or sad your emotions can raise your pulse. Body size: Body size usually doesn t change pulse. If you re very obese, you might see a higher resting pulse than normal, but usually not more than 100. Medication use: Meds that block your adrenaline (beta blockers) tend to slow your pulse, while too much thyroid medication or too high of a dosage will raise it. If you re on a beta blocker to decrease your heart rate (and ) or to control an abnormal rhythm ( ), your doctor may ask you to monitor and log your heart rate. Keeping tabs on your heart rate can help your doctor determine whether to change the dosage or switch to a different medication. If your pulse is very low or if you have frequent episodes of unexplained fast heart rates, especially if they cause you to feel weak or dizzy or faint, tell your doctor, who can decide if it s an emergency. Your pulse is one tool to help get a picture of your health. (abnormal heart rhythms) This content was last reviewed July 2015.
