A thorough analysis of your heart's electrical activity is called an electrophysiology study (EP study). Electrocardiogram (EKG) tracings and electrical measurements inside your heart are produced using cardiac catheters and computers.

Your cardiologist may safely replicate your aberrant heart rhythm during the test, after which you'll receive various drugs to determine which one best regulates the rhythm.

Your doctor uses the EP study to:

• Learn the cause of your dysrhythmia or arrhythmia, which is an irregular heartbeat.

• Identify the location in your heart where the aberrant heart rhythm starts.

• Choose the best treatment for your irregular heart rhythm.

When other tests, such as a regular EKG, Holter monitor, event recorder, stress test, echo, or angiography, cannot offer enough data to fully analyse your aberrant cardiac rhythm, your doctor may advise an EP study.

The operation is conducted in a clinical setting with strict controls in an electrophysiology lab. Cardiologists and electrophysiology-trained nurses carry out the operation.

In general, an EP study is a highly safe technique. There are hazards, though, just like with any invasive operation. To reduce these dangers, certain safety measures are implemented. Any worries about the procedure's hazards and advantages should be brought up with your doctor.

An electroencephalogram (EEG) test uses tiny metal discs (electrodes) connected to the scalp to assess electrical activity in the brain. Electrical impulses are the primary means of communication among brain cells, which are always active—even while you're asleep. Wavy lines can be seen during this activity on an EEG recording.

One of the primary diagnostic procedures for epilepsy is an EEG. Other brain abnormalities can also be identified using an EEG.

When diagnosing brain illnesses, particularly epilepsy or another seizure disorder, an EEG can identify variations in brain activity. An EEG could be useful for identifying or treating:

• Brain cancer

• Head injury-related brain damage

• Various conditions can lead to brain dysfunction. (encephalopathy)

• Sleep problems

• Inflamed brain tissue (herpes encephalitis)

• Stroke

• Alzheimer's disease

A chronic coma patient's brain death may also be verified using an EEG. For a patient in a coma that has been medically induced, a continuous EEG is utilised to determine the appropriate level of anaesthesia.

An electromyography (EMG) diagnostic test is used to evaluate the condition of the muscles and the nerve cells that govern them. (motor neurons). The results of an EMG can identify difficulties with nerve-to-muscle signal transmission, muscle dysfunction, or both.

Electrical signals sent by motor neurons trigger muscle contractions. An EMG converts these impulses into graphs, noises, or numerical values that are subsequently evaluated by an expert using tiny apparatuses called electrodes.

A needle electrode is placed into a muscle during a needle EMG to record the electrical activity of that muscle.

The nerve conduction study, a component of an EMG, measures the speed and strength of impulses moving between two or more sites using electrode stickers attached to the skin (surface electrodes).

Your doctor might recommend an EMG if you exhibit any indications or symptoms pointing to a nerve or muscle tissue. Such signs might consist of the following:

• Tingling 

• Numbness

• Muscle tremor

• Cramping or aching muscles

• Some forms of limb discomfort

A low-risk procedure, EMG rarely has problems. Where a needle electrode is implanted, there is a slight possibility of bleeding, infection, and nerve damage.

There is a slight chance that air could seep into the space between the lungs and chest wall during a needle electrode examination of the muscles along the chest wall, leading to lung collapse. (pneumothorax).

The BERA hearing test is an electrophysiological test method that aids in locating and analysing the electrical potential produced at various levels of the auditory system, starting from the cochlea to the cortex. BERA is the most accurate and sensitive method for detecting lesions in the brainstem's VIII nerve and auditory pathway, especially in adults. 

Although numerous pure tones and impedance audiometric tests are specifically created to distinguish between cochlear and retrocochlear hearing loss, BERA is the most sensitive method. It is also the most affordable way to diagnose retro cochlear lesions and is non-invasive, simple to record, and unaffected by age, drowsiness, or anaesthesia.

The most affordable way to diagnose retro cochlear abnormalities is non-invasive, easily recordable, unaffected by age, drowsiness, or anaesthesia.

Additionally, pure tone audiometric examinations on children are frequently impractical, but BERA offers a quick and effective technique to check for deafness in newborns. As one of the most crucial objective techniques for assessing the peripheral auditory system in neonates, infants, sedated and comatose patients, as well as other non-linguistic individuals, this hearing test is the most precise and sensitive test for brain stem pathology.

When it comes to several things, healthy hearing is crucial. However, normal hearing comprises the auditory nerve, which can quickly send sound impulses from the ear to the brain. Under the right guidance of our specialists, this BERA test at our Asha Speech and Hearing clinics can reveal if nerves transmit sound impulses to the brain and whether the pace of sound delivery is within normal bounds.

The kind of defect (conductive or sensorimotor), severity (hearing threshold), and location of the child's hearing loss (inner ear or other regions) can all be identified by the specialists using the results of this hearing test.

The electrical signal that your visual cortex, a part of your brain, produces in response to visual stimulus is measured by a Visual Evoked Potential (VEP) test. It is also known as a visual evoked response test. (VER).

A VEP test precisely evaluates the performance of your visual pathway, which comprises your:

• Eyes.

• Eye nerves.

• Ocular chiasm (the place in your brain where some of the optic nerve fibres coming from one eye cross optic nerve fibres from the other eye).

• Optic nerve (the pathway between the optic chiasm and your brain).

• Optical radiance (the part of your visual pathway that transmits visual input coming from your retina, optic nerve and optic tract).

• Brain cortex.

Any issue that impacts your brain's visual cortex or pathways may appear abnormal on the VEP test.

Tests for visually evoked potentials can be used to identify or help diagnose the following conditions:

• Multiple Sclerosis

• Glioma

• Brain Trauma

• Hydrocephalus

• Toxic Optic Neuropathy

• Other types of Optic Neuropathy

• Infection-related problems with the visual system, such as meningeal TB.

Nerve dysfunction and injury are evaluated using a Nerve Conduction Velocity (NCV) test. The test, sometimes called a nerve conduction study, gauges the speed at which electrical signals pass through your peripheral nerves.

Where the nerve root emerges from the spinal cord is where your peripheral nerves begin. You can move your muscles and use your senses thanks to these nerves. Electrical signals are sent more swiftly and forcefully by healthy nerves than by damaged nerves.

Your doctor can distinguish between damage to the myelin sheath, the nerve's protective coating, and damage to the nerve fibre with the aid of the NCV test. Additionally, it can assist your doctor in determining if a condition is caused by a nerve injury that has impacted the muscles or a disorder of the nerves.

For a proper diagnosis and choosing your treatment plan, it's crucial to make these distinctions.

Numerous muscle and neuromuscular conditions, including the following, can be identified using an NCV test:

• The syndrome of Guillain-Barré

• Palmar-plantar syndrome

• Cuneiform tunnel syndrome

• The illness Charcot-Marie-Tooth (CMT)

• A disease of the herniated disc

• Neuropathy and chronic inflammatory polyneuropathy

• Issues with the sciatic nerve

• Damage to peripheral nerves

• Musculoskeletal injuries

Your doctor might advise an NCV test if they think you have a pinched nerve.

Along with an NCV test, an electromyography (EMG) test is frequently conducted. The electrical signals passing through your muscles are captured during an EMG exam. This aids in determining the existence, location, and severity of any illness that may harm the muscles and nerves.

Heritage Hospitals should be your first choice if you or someone close is advised for an NCV test in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

When you have symptoms of muscle exhaustion, an RNST test is administered. It frequently identifies neuromuscular junction illnesses, including Lambert-Eaton Myasthenic Syndrome (LEMS) and Myasthenia Gravis (MG).

An electrode for recording will be put on the tested muscle to capture the nerve response to repeated electrical shocks. Between each round of electrical stimulation, you can be asked to exercise the muscle being evaluated for a few seconds to several minutes. Depending on your symptoms, several muscles and nerves may be checked.

The RNS (Repetitive Nerve Stimulation) Test is used to diagnose and assess symptoms, including-

• Insufficiency & Fatigability

• Ptosis (Drooping of eyelids)

• Diplopia (Double vision)

• Dysphagia (Difficulty in swallowing)

• Dysarthria (Slurred speech)
