An arrhythmia is defined as any change in rhythm to the heartbeat (irregular heartbeat).

Tachycardia is any condition in which the heart beats too quickly; bradycardia, in contrast, occurs when the heart beats too slowly or in an irregular pattern.

One of the most common types arrhythmia is atrial fibrillation, a fast, irregular heart rhythm that can sometimes lead to stroke or heart failure.

Symptoms of arrhythmia

• Shortness of breath
• Fast or slow heart rate
• Chest discomfort
• Sweating
• Lightheadedness or dizziness

Causes of arrhythmia

• Congenital heart problems

• Electrolyte imbalances (such as sodium or potassium) 
• High blood pressure

Care for arrhythmias includes cardioversions, ablations, or pacemaker/ICD (implantable cardiac device)/ Loop recorders device implants.
