Arrhythmia
Arrhythmia is also known as Cardiac dysrhythmia, heart rhythm disorder and irregular heartbeat.
occurs when the electrical impulses that coordinate heartbeats don't work properly, causing the heart to beat too fast, too slow or irregularly in general.
affects the amount of blood pumped by the heart.
May feel like a fluttering or racing heart.
Some arrhythmias, however, especially if they veer too far from a normal heartbeat or result from a weak or damaged heart, may cause troublesome and even potentially fatal symptoms.

Symptoms of the Disorder
Arrhythmias may cause blood flow in your brain and body to decrease, this can lead to heart palpitation, dizziness, fainting, weak, shortness of breath, or even death

There are many types of arrhythmia, some have no symptoms or warning signs, some are not very serious and others may be life threatening

Symptoms of arrhythmia vary depending on how healthy your heart is and the type of arrhythmia you have, how severe it is, how often it happens or how long it lasts
• Even if a patient notices a symptom, it does not mean that it is a serious problem
• Some patients with life-threatening arrhythmias have no symptoms, while others with symptoms may not have a serious problem
• If you have bradycardia, you may feel tired (a slower heartbeat)
• If you have tachycardia, your heartbeat will feel like a strong pulse in your neck (a faster heartbeat)
• If any of these symptoms occur more often, it is recommended to be checked up by a doctor immediately
Impacts on Daily Lives of Patients
• Many types of Arrhythmia- impact on daily life depends on which type you have

• Many types of arrhythmia are harmless and do not effect daily life

• Although it is recommended to keep medication ongoing and to always report side effects of medication to doctors which can disable daily activities such as driving

• It is recommended to always seek assistance when you feel these side effects because it can cause impaired driving

.• Certain restrictions are also placed on daily life for
example to not do any strenuous physical activity that causes your heart beat to speed up or make symptoms worse if you have any
Treatment
Impact on
Family Members



Medication
Antiarrhythmic- reverts abnormal heart rhythm to a normal rhythm
Beta blockers -reduce blood pressure and help blood vessels open up to improve blood flow.
Lifestyle
Eat a healthy diet to support healthy heart function
Increase consumption of fiber, green leafy vegetables, Magnesium (tofu/nuts), and Coenzyme Q10 to improve energy metabolism within the heart and boost blood supply to the heart.
Eliminate salt and saturated fats
Engage in regular physical activity

Implantable devices
Pacemakers- helps control abnormal heart rhythms by emitting electrical impulses that stimulate the heart to beat at a normal rate.

Implantable Cardioverter defibrillators- uses electrical pulses or shocks to help restore a normal heart rhythm.
• Family members should be aware of all side effects of arrhythmia

• They should also be prepared for any sudden side effects such as sudden cardiac death which has recently gone up to 50%---in order to prevent such things from happening family members should make sure that cardiac risk factors are reduced

• Several types of arrhythmia are genetic, so family members should get a check up to see if they have arrhythmia

• Family history plays a large role in determining if you have arrhythmia- if you have a parent with high blood cholesterol, someone who died suddenly, there is a chance that you may have a heart defect such as arrhythmia
