why does my heart beat irregularly sometimes

Electrophysiology study -- This test records your heart's electrical activities and pathways. It can help find out what's causing heart rhythm problems and find the best treatment for you. During the test, your doctor will safely reproduce your abnormal heart rhythm and then may give you different medications to see which controls it best, or to see what procedure or device you need to treat it. Head-up tilt table test -- Doctors use this test to find out what's causing fainting spells. It measures the difference in heart rate and blood pressure when you're standing up or lying down. You'll get this test in a lab. You'll lie on a stretcher, tilted at different angles while you're getting an EKG and specialists are checking your blood pressure and oxygen level. This shows if symptoms of passing out are due to the electrical system, the nervous system, or the vascular system. What Is Electrical Cardioversion? If drugs can't control a persistent irregular heart rhythm (such as atrial fibrillation), you might need. For this, doctors, give you a short-acting anesthesia, then deliver an electrical shock to your chest wall to allow the normal rhythm to restart.

What Is a Pacemaker? This device sends small electrical impulses to the heart muscle to keep a safe heart rate. The pacemaker has a pulse generator (which houses the battery and a tiny computer) and wires that send impulses from the pulse generator to the heart muscle. What Is an Implantable Cardioverter Defibrillator (ICD)? Doctors mainly use ICDs to treat ventricular tachycardia and ventricular fibrillation, two life-threatening heart rhythms. The ICD constantly tracks the heart rhythm. When it detects a very fast, abnormal heart rhythm, it delivers an electric shock to the heart muscle to cause the heart to beat in a normal rhythm again. There are several ways the ICD can be used to restore normal heart rhythm. They include:
Anti-tachycardia pacing (ATP). When the heart beats too fast, you get a series of small electrical impulses to the heart muscle to restore a normal heart rate and rhythm.

Cardioversion. You may get a low-energy shock at the same time as the heart beats to restore normal heart rhythm. Defibrillation. When the heart is beating dangerously fast or irregularly, the heart muscle gets a higher-energy shock to restore a normal rhythm. Anti-bradycardia pacing. Many ICDs provide back-up pacing to maintain heart rhythm if it slows too much. In rare cases, palpitations can be a sign of a more serious condition. So, if you have heart palpitations, see your doctor. Get immediate medical attention if they come with: After your doctor takes your medical history and looks you over, he may order tests to find the cause.

Vigorous, nicotine, or illegal such as and Medical conditions, including disease, a level, and Hormonal changes during, or just before menopause.

Sometimes, palpitations during pregnancy are signs of. , including, and some drugs used to prevent arrhythmias (a serious heart rhythm problem) or treat an underactive Some herbal and nutritional Some people have palpitations after heavy meals rich in carbohydrates, or fat. Sometimes, eating foods with a lot of monosodium glutamate (MSG), nitrates, or sodium can bring them on, too. If you have heart palpitations after eating certain foods, it could be due to food sensitivity. Keeping a food diary can help you figure out which foods to avoid. They can also be related to. When they are, theyБre more likely to represent.
