World Heart Rhythm Week

World Heart Rhythm Week, observed annually from June 3rd to June 9th, is a global initiative aimed at raising awareness about heart rhythm disorders and promoting cardiovascular health

Arrhythmias include many conditions such as bradycardias and tachycardias. Additional heart rhythm disorders are:

Adams-Stokes Disease

Adams-Stokes Disease, also called Stokes-Adams disease, refers to a heart block or other arrhythmia that can slow the heart rate considerably, causing fainting (syncope) or convulsions. It’s caused when the heart’s electrical signals are interrupted as they pass from the upper (atria) to the lower (ventricles) chambers.

Atrial flutter

Atrial flutter occurs when rapidly firing electrical signals cause the muscles in the heart’s upper chambers (atria) to contract at a very rapid rate (250 to 350 times per minute). This leads to an overly fast heartbeat, which can have either a regular or irregular rhythm.

Atrial flutter is much less common than atrial fibrillation (AFib or AF), but its causes and consequences are similar. Patients with atrial flutter can also have periods of atrial fibrillation.

Symptoms of atrial flutter

Atrial flutter may present with a heartbeat that’s overly fast, irregular or with heart palpitations (feeling a hard, fast or irregular heartbeat in the chest). Other symptoms include:

If you experience these symptoms and think you may have atrial flutter, contact your health care professional immediately.

Comorbidities and Risk Factors

Atrial flutter is often associated with other conditions such as:

Sick sinus syndrome

When the sinus node (also called the sinoatrial or SA node) doesn’t produce its electrical signals properly, the heart rate slows down, pauses or speeds up. This is referred to as sick sinus syndrome.

In this condition, the heart rate can fluctuate between an overly slow rate (bradycardia) and an overly fast rate (tachycardia).

Sinus arrhythmia

Common in children, this type of irregular heart rhythm refers to changes in the heart rate during breathing. The heart rate speeds up for a few beats during inhalation and slows down during exhalation. Sinus arrhythmia is normal.

Wolff-Parkinson-White Syndrome (WPW)

In this disorder, the electrical pathways between the heart’s upper (atria) and lower (ventricles) chambers malfunction. This allows electrical signals to reach the ventricles too early. Those electrical impulses can then be “bounced back” to the atria.

This can produce overly fast heart rates. Other people with WPW Syndrome may not experience any overt symptoms, but still face serious risk.

Some people with WPW also have atrial fibrillation.

Diagnosis and treatment

Your health care professional can detect WPW Syndrome through an electrocardiogram (EKG or ECG). This non-invasive test can reveal irregularities in your heart rhythm.

Your treatment plan will depend on several factors, including your risk of future arrhythmias as well as the frequency and severity of your symptoms. People who don’t experience symptoms may not require treatment.

Possible treatment options for WPW Syndrome may include:

Ablation is the most common treatment for WPW Syndrome. It has a high success rate and a low risk of complications.
