Treadmill Test (TMT) is done to find the stress on the heart. On the machine the patient walks and the readings are taken. Treadmill Test machines our hospital has are of the latest models.
Electrocardiography (ECG or EKG) is the recording of the electrical activity of the heart over time via skin electrodes.
An ECG displays the voltage between pairs of these electrodes, and the muscle activity that they measure, from different directions, also understood as vectors. This display indicates the overall rhythm of the heart and weaknesses in different parts of the heart muscle. It is the best way to measure and diagnose abnormal rhythms of the heart, particularly abnormal rhythms caused by damage to the conductive tissue that carries electrical signals, or abnormal rhythms caused by levels of dissolved salts (electrolytes), such as potassium, that are too high or low. In myocardial infarction (MI), the ECG can identify damaged heart muscle. But it can only identify damage to muscle in certain areas, so it can't rule out damage in other areas. The ECG cannot reliably measure the pumping ability of the heart; for which ultrasound-based (echocardiography) or nuclear medicine tests are used.
ECG is done with 12 channels and report is generated automatically by computer. We provide the most accurate diagnosis using ECG to facilitate the doctor from taking the further steps towards treating the patients.
EEG
EEG can determine changes in your brain activity which may be useful in diagnosing brain disorders, especially epilepsy. An EEG may be helpful to confirm, rule out or provide information the helps with management of the disorders such as:
Sleep Studies:
A sleep study generates several records of activity during several hours of sleep, usually about six. Generally, these records include an electroencephalogram, or EEG, measuring brain waves; an electroculogram, or EOG, measuring eye and chin movements that signal the different stages of sleep; an electrocardiogram, EKG, measuring heart rate and rhythm; chest bands that measure respiration; and additional monitors that sense oxygen and carbon dioxide levels in the blood and record leg movement. None of the devices is painful and there are no needles involved. The testing procedure as a whole is known formally as “polysomnography,” and the technician who supervises it is usually a “registered polysomnographic technologist,” or RPT. Usually the bedroom where the test is conducted is more like a comfortable hotel room than a hospital room.
Our doctors here might prescribe a “split-night study,” in which the first hours are devoted to sleep apnea diagnosis. If obstructive sleep apnea is found, the patient is awakened and fitted with a positive airway pressure device. The remainder of the patient‘s slumber is then devoted to determining how well he or she responds to PAP therapy
A substantial amount of data is generated by a sleep study, but the most crucial is the apnea-hypopnea index, or AHI. An apnea is a complete cessation of breathing for 10 seconds or longer. A hypopnea is a constricted breath (more than one-fourth, less than three-fourths) that lasts 10 seconds or longer. The index number is the number of apneas and hypopneas the sleeper experiences each hour. An AHI of 5 to15 is classified as mild obstructive sleep apnea; 15 to 30 is moderate OSA; 30 or more is severe OSA. Here is more information about understanding the results of your sleep study. If you are diagnosed with OSA, its severity is one of the factors you and your sleep specialist will weigh as you explore your treatment options.
