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
- Lightheadedness or dizziness
Causes of arrhythmia
- Congenital heart problems
- Coronary artery disease
- 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.
