Pacemakers

The pacemaker is a device which delivers an electrical impulse to control your heart rhythm, typically for patients who suffer from bradycardia (an abnormally slow heartbeat).

The sinoatrial node is the natural pacemaker of the heart. It sends action potential to depolarise nodal cells in the heart to create rhythmic contractions. For patients with an irregular heartbeat rhythm, the pacemaker aids and maintains consistent contractions.


They can also be implanted temporarily to treat a slow heartbeat after a heart attack, major surgeries, or drug overdose. Permanent pacemakers are highly recommended for patients with a slow or irregular heartbeat or, in some people, heart failure.

It is implanted in the soft tissue beneath the skin in the chest. It is typically inserted in the chest below the collarbone.

Parkinson's Disease

Parkinson’s disease is a progressive nervous system disorder that affects one’s movements. Parkinson’s disease signs and symptoms are different for every individual and may go unnoticed in the early stage. Symptoms typically start on one side of the body and remain worse on that side even after the symptoms begin appearing in both sides of the body.  Generally, the symptoms of Parkinson’s disease include tremors, slowed movement, rigid muscles, impaired posture and balance, loss of automatic movements such as blinking or swinging of arms when walking, and speech and writing changes.  Parkinson’s disease occurs when neurons in an area of the brain that controls movement becomes impaired or dies. These neurons normally produce dopamine. As more neurons become impaired or die, the amount of dopamine produced in the body is reduced significantly, causing the movement problems associated with Parkinson’s disease.  People with Parkinson’s also lose the nerve endings that produc...

Tinnitus

Tinnitus can also cause other types of noise in your ears such as: buzzing, roaring, clicking, hissing and humming.  The pitch heard from tinnitus can vary from a high squeal to a low roar, this can affect the patient’s ability to detect tinnitus from external sounds Tinnitus can develop gradually over time or occur suddenly. It is often associated with: age-related hearing loss, inner ear damage, earwax build-up and middle ear infection However, one in every three people with tinnitus doesn't have any obvious problem with their ears or hearing.

Pompe Disease

Pompe disease is a rare genetic condition where the body is unable to break down complex sugars. This is due to a deficiency in an enzyme called acid alfa glucosidase (GAA). Mutations in the GAA gene causes this disorder and results in a build up of glycogen in cells.  Pompe disease can appear in patients from within a few months of birth, at about 1 years old and even during the teenage years.  Those with Pompe disease usually inherit the disease from their parents. However, the allele for the disease is recessive, and may not be expressed in the parents. This disease is typically associated with weak muscles, poor muscle tone and an enlarged liver. However, there are many complications with regards to the respiratory system and motor skills which can also develop.  Enzyme replacement treatment is used for all Pompe patients. A drug called aglucosidase alfa is given intravenously, which acts as a replacement for GAA. Sources: https://my.clevelandclinic.org/health/disease...
