Arrhythmias are very common in older adults. Atrial fibrillation (a common type of arrhythmia that can cause problems) affects millions of people, and the number is rising.
Most serious arrhythmias affect people older than 60. This is because older adults are more likely to have heart disease and other health problems that can lead to arrhythmias.
Older adults also tend to be more sensitive to the side effects of medicines, some of which can cause arrhythmias. Some medicines used to treat arrhythmias can even cause arrhythmias as a side effect.
Some types of arrhythmia happen more often in children and young adults. Paroxysmal supraventricular tachycardia (PSVT), including Wolff-Parkinson-White syndrome, is more common in young people. PSVT is a fast heart rate that begins and ends suddenly.
Arrhythmias are more common in people who have diseases or conditions that weaken the heart, such as:
Other conditions also can raise the risk for arrhythmias, such as:
Several other risk factors also can raise your risk for arrhythmias. Examples include heart surgery, certain drugs (such as cocaine or amphetamines), or an imbalance of chemicals or other substances (such as potassium) in the bloodstream.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Arrhythmia, visit www.clinicaltrials.gov.
