From the Guidelines
Irregular heartbeats, also known as arrhythmias, are abnormal heart rhythms that can cause the heart to beat too fast, too slow, or with an uneven pattern, and can be identified on an electrocardiogram (ECG) as an irregular ventricular rate, which suggests atrial fibrillation (AF), multifocal atrial tachycardia (MAT), or atrial flutter with variable AV conduction 1.
Types of Irregular Heartbeats
- Atrial fibrillation (AF): characterized by an irregular and often rapid heart rate, which can increase the risk of stroke, heart failure, and other heart-related complications 1
- Multifocal atrial tachycardia (MAT): a type of arrhythmia that occurs when there are multiple areas of abnormal electrical activity in the atria, leading to an irregular heart rhythm 1
- Atrial flutter: a type of arrhythmia that occurs when there is a problem with the electrical signals in the atria, leading to a rapid and irregular heart rhythm 1
Diagnosis and Treatment
- A 12-lead ECG can help diagnose irregular heartbeats and identify the underlying cause, such as AF, MAT, or atrial flutter 1
- Treatment for irregular heartbeats depends on the type and severity of the condition, and may include lifestyle changes, medications, or procedures such as cardioversion or ablation 1
Importance of Seeking Medical Attention
- If you experience persistent symptoms of irregular heartbeats, such as palpitations, dizziness, shortness of breath, chest pain, or fatigue, you should seek medical attention as some arrhythmias can lead to serious complications if left untreated 1

From the Research
Definition of Irregular Heartbeats
- Irregular heartbeats, also known as cardiac arrhythmias, are characterized by an irregular rhythm of heartbeat, which can be either too slow (<60 beats/min) or too fast (>100 beats/min) 2.
- This condition can occur at any age and may require the use of pacemaker and defibrillators devices, as well as antiarrhythmic medications for treatment 2.
Types of Irregular Heartbeats
- Supraventricular tachycardia (SVT) and Ventricular tachyarrhythmias (VT) are types of arrhythmias that can be treated with beta blockers 3.
- Other types of arrhythmias include Atrial Fibrillation, Long QT syndrome, and arrhythmias associated with congenital heart disease, cardiomyopathies, and post-cardiac surgery 3.
