Heart Rhythm Society Health Policy Initiative advocates for evidence-based, guidelines-driven, quality health care and fair reimbursement to healthcare providers, advance the development and implementation of performance measures that lead to improved health outcomes for patients with heart rhythm disorders, and collaborate with the American Medical Association, medical specialty societies, regulatory agencies, and manufacturers to improve access to treatments and appropriate specialty and sub-specialty care. More than 14 million Americans are currently living with heart rhythm disorders, the primary cause of heart disease-related disability and death.
The Heart Rhythm Society HRS is the preeminent organization for promoting research to end death and suffering from heart rhythm disorders. The Patient Resources section is intended to provide accurate and clear information about cardiac rhythm disorders. A block can also occur along other pathways to each ventricle. Depending on the location and type of block, the impulses between the upper and lower halves of your heart may be slowed or blocked. If the signal is completely blocked, certain cells in the AV node or ventricles can make a steady, although usually slower, heartbeat.
Although it often feels like a skipped heartbeat, a premature heartbeat is actually an extra beat.

Even though you may feel an occasional premature beat, it seldom means you have a more serious problem. Still, a premature beat can trigger a longer lasting arrhythmia — especially in people with heart disease.
Premature heartbeats are commonly caused by stress, strenuous exercise or stimulants, such as caffeine or nicotine. When your heart quivers, it's unable to pump blood effectively, which can cause blood to pool. This can cause blood clots to form.

If a clot breaks loose, it can travel from your heart to your brain. There it might block blood flow, causing a stroke. Certain medications, such as blood thinners, can greatly lower your risk of stroke or damage to other organs caused by blood clots. Your doctor will determine if a blood-thinning medication is appropriate for you, depending on your type of arrhythmia and your risk of blood clots.
To prevent heart arrhythmia, it's important to live a heart-healthy lifestyle to reduce your risk of heart disease. A heart-healthy lifestyle may include:. Heart arrhythmia care at Mayo Clinic.

Recent years have seen the publication of many textbooks on cardiac arrhythmias, some of which concentrate on one particular aspect such as drug management, electrocardiographic appearances, electrophysiological evaluation etc; and others of which are the collated reports of symposia, often dealing with detailed con- siderations of highly specialised problems.
