What is ILR implantation?

An implantable loop recorder(ILR), also known as an insertable cardiac monitor, is a small device that is implanted under the skin of the chest for cardiac monitoring, to record the heart's electrical activity for an extended period. This device acts as an electrocardiogram (ECG), continuously recording electrical signals from the heart. This helps find arrhythmias that can cause various problems such as fainting.


A special group of cells usually initiates an electrical signal to initiate a heartbeat. These cells are located in the sinus node (SA). This nodule is located in the right atrium, the upper right chamber of the heart. The signal travels rapidly through the heart's conduction system to the ventricles. These are the two lower chambers of your heart. When it moves, the signal causes nearby parts of the heart to contract. This helps the heart to pump blood in a coordinated manner.



Disturbances in this signaling pathway can lead to cardiac arrhythmias. These can cause many problems such as B. Fainting and palpitations. An arrhythmia (arrhythmia) prevents the heart from pumping as much blood as it needs. A temporary reduction in blood flow to the brain causes fainting. When the rhythm returns to normal, people usually regain consciousness.


If you have fainting spells or heart palpitations and other tests are still unanswered, you may need a loop recorder. Repeated fainting spells can negatively affect physical and mental health. Also, certain types of fainting greatly increase the chance of sudden death. These fainting spells should be diagnosed and treated as soon as possible.


Older people with unexplained falls may also need a loop recorder. Healthcare providers may use it in people who are thought to have epilepsy and do not respond to medication. In either case, the recorder can determine if abnormal rhythms are a problem.


The procedure takes about 10 to 15 minutes.

Subcutaneous implantable cardioverter-defibrillator

Image
  A subcutaneous implantable cardioverter-defibrillator (S-ICD) is a type of defibrillator that is implanted under the skin on the chest. Unlike traditional implantable cardioverter-defibrillators (ICDs), which are implanted in the chest with wires inserted into the heart, the S-ICD system is implanted under the skin and does not require any wires to be inserted into the heart. The S-ICD system includes a pulse generator that is implanted under the skin on the left side of the chest, and a lead that is placed under the skin and runs along the left side of the breastbone. The lead senses the heart's electrical activity and delivers a shock to the heart if it detects a life-threatening rhythm. S-ICD s are typically used in patients who are at risk for sudden cardiac death due to a high risk of ventricular arrhythmias, but who do not have a need for pacing therapy. S-ICDs are an alternative to traditional ICDs and can be useful in patients who are unable to tolerate a trans venous IC...

Permanent Pacemaker

Image
  Pacemakers can be defined as devices that are placed in your body by surgery to support the electrical system in your heart. It is generally used to stabilize abnormal heart rhythms and prevent life dangering or disrupting chances. Single-chamber pacemakers use a single wire attached to one chamber of your heart, whereas Dual-chamber pacemakers use two wires.  A pulse generator is a small metal case that contains an electronic circuit with a small computer and battery that regulates the pulses sent to the heart. A lead is an insulated wire that connects to the pulse generator at one end and is placed in one of the heart chambers at the other end. Leads are most often placed through large veins in the chest that lead directly to the heart. An electrode at the tip of the lead contacts the heart wall. The leads send electrical impulses to the heart. It also senses the heart's electrical activity and sends that information back to the pulse generator. Pacing leads are placed in...

HEAD AND NECK CANCER

Image
  Head and Neck Cancer  is begin with the squamous cells which line the mucosal surface of the Head and Neck area. Likewise inside the mouth, voice box, throat, and other parts of the salivary gland, sinuses, muscles, and nerves in the head and neck. Cancers like the brain, thyroid gland, eyes, and skin of the head and neck area are not considered Head and Neck Cancer. If the squamous cells of carcinoma of the head and neck area are spreading, it can harm the crucial part of the head and neck part. The cancerous cells in lymph nodes are found in the upper neck when such evidence of cancer is not found in other parts of the area because the actual primary tumor is comparatively small. SYMPTOMS A lump in the neck, a sore that won’t go away and may hurt, a sore throat that won’t go away, trouble swallowing, a change in voice quality, or hoarseness are all possible signs of head and neck cancer. Other, less serious illnesses may also be at blame for these symptoms. Any of these sy...
